Strumpy Shader Editor [Now Open Source]

I am trying to make a simple snow shader based on world normal direction, I got the easy part (worldnormal -> Split node's Y to arg3 of lerp node) but I have no idea how to make the snow falloff more random, it is only straight line which does not look very good to me.

If some one could give me some hints I would appreciate that a lot.

 

Thanks for reading my post. I'll explain in more detail, but please be aware the bulk of my shader knowledge come from Mental Ray, so I apologise if I've misunderstood something.

I'm trying to make a very simple shader, I only want surface shading, not diffuse shading. Partly because of the look, largely for performance.

So I plug a Zero constant into diffuse. Would be nice if diffuse could just be turned off.

Now as soon as I plug my maintex into emission, my lightmaps fail to render. I understand that maintex is supposed to be in diffuse, and then the lightmaps work automatically as you've said. I just don't want any diffuse shading.

So I take my maintex, add it to my rim shading, and plug it into emissive. Except for not being able to multiply it with my lightmaps, it looks perfect.

So guess it comes down down to being able to disable channels (for performance), and have access to the lightmap textures in the event that your overriding what Unity attempts to do automatically. Incidentally, trying to access them from an input seems impossible at the moment because they're labelled unity_Lightmap, thus don't start with the underscore that SSE forces.

At the moment, the only workaround I've got working is using the diffuse channel for my textures, and putting all of my geometry in a layer and masking it from all of my lights. This works, but is a bit of a pain, makes baking lighting annoying, and still seems to take about 10% longer to render, than my custom shading graph that seems to ignore the lightmaps.

I know I've rambled a lot, but I feel these additions would be great for a variety of mobile based shaders.

 

Dangermouse, doesn't unity come with a mobile-optimized Unlit light-mapped shader?

Pretty sure I've seen one in one of the example packages before, it was just a simple fixed-function shader with all lighting disabled. Pretty sure one of the demos unity has on the apppstore even uses it.

Trying to roll your own using the emission channel in SSE seems like a strange path to take on a quest for performance.

 

You misunderstand. I'm not trying to just make a lightmapped shader. I have one already that I made myself, and still use a lot of the time. It has lighting turned off, and just returns unity_Lightmap*_Maintex and nothing else

What I'm working on though is a rimshader that also takes vertex colour into account, and a few other shennanigans, for special objects in my gameworld. For that I've used SSE because I have NO idea how I'd do it myself. But currently SSE is forcing diffuse shading, and if I plug a constant into the diffuse channel, it breaks my lightmaps. I have to unlink all my lights to get it to even look right.

Is there someething I'm misunderstanding? I apologise if there is.

 

Hello ,

I would like to add a new node to SSE to minimise my shader network. I saw an old post by Stramit saying that this is possible by implementing the 'Node" interface etc :

Anyone know where the API docs are? I could not find any them anywhere in the package, strumpy.net or in this thread . Right now all the code for the nodes seems compiled into the "StrumpyShaderEditor.dll". I had a look at this assembly in the Monodevelop, however before stepping in to develop my own nodes, I would like to know if anyone knows if there are API somewhere docs or atleast one node implementation so i get the field markup right.

cheers!

 

I think that's for the next version if i'm not mistaken

 

Wow, that's surprising. I found the first comment on the API on the first page of this thread. I read somewhere on this thread of a possible 'major rewrite' of the SSE, perhaps the API is changing as well.

The docs would be welcome whenever they arrive. I must say though SSE is proving to be a lot of fun to play around with! Thanks for the good work Stramit Texel!

 

Yeah last time i heard it's being rewritten from scratch, So I guess we just wait for the next version since it could be different from the current version. I think...

 

Truing to make fake SSS shader or something.

Attempt with sss mask and ramp (in lighting graph), so it works in penumbra but not working in shadow.


Is there any chance to get lighting ramp for full model, not only lighted part?


Is it possible to see or get camera lighting (or shadow) pass?

 

hello everywhere

I tried to archieve a correct hair shader (not satisfied with the transparent or cutout built in shader)
I have got for now a correct transparency but no normal or specular effect

my shader

transparent bumped specular

and my graph


thanks for viewing

 

I am seeing the world position data coming in as several colors, so I tried adjusting the data and applying it as a mask. Then lerp the two textures together using that mask but the results are not what I expected.

Is there any way I can debug the output of some of these nodes? And is there a way to break a node's connection without having to delete it?



Another attempt. I inverted the position coming back from world data to make it a negative value. Then added the base height amount before the blending should begin and then took the absolute value of that.

Example: If I wanted to blend at y = 100 or higher and Vertex y position is at 128.
Abs(-128 + 100) = 28

Then I passed this information to a Mask node and tell the Lerp function to blend based off that mask?



Any help is appreciated.

Did you forget the download link or am I just missing it?

 

Still working on it and I added the sgraph to the post for anyone interested in taking a look at it. Basically I am trying to make a terrain shader that will take several maps and blend them together based off of the Y value of the vertex. Right now just trying to get familiar with the shader editor and just get two of these textures blending.

If you are curious why I am trying to do this, it is because I am working on a game that is using imported Mesh's for the terrain rather than Unity's terrain system.



Thanks for all the help stramit!

Thanks for the update Stramit. It would be great to see more graph setups (examples) included in future releases. Or perhaps, maybe user contributed ones (if people are interested in sharing).

 

That's awesome Stramit , thanks. Looking at the nodes at first glance I think that's all that I need. To share my shader graphs, I think I can always attach an additional archive/unitypackage containing my node classes along with the sgraph. That 'should' work out, Even if it doesn't it beats hand-editing shaders to call my code after an SSE session.

 

Oh, this is nice. Thanks stramit.

Well i guess now you can create a custom node then . Good Luck.

 

thanks for the update ,great work

 

Damn... this won't work in 3.4 ... and I really don't want to use a beta 3.5 of Unity

 

Damn... this won't work in 3.4 ... and I really don't want to use a beta 3.5 of Unity... I am getting an error that says failed to import package...

 

This may have been asked or answered already, but is it possible to edit already created shaders?

I found a shader with some really cool effects, but I'd like to do a smooth transition between it and a normal defuse shader.

Is this possible?

Thanks.

 

@Dreamcube017 : What SSE produces is just regular CG code , so yes u can edit them by manually editing the resultant ".shader" file. However blending between 2 shaders is difficult to do without involving some ugly state management in script . You haven't mentioned what this "shader with some really cool effects" does or if you have the .sgraph of this shader. So the question is a bit vague.

In general the effect you're looking for maybe possible using the following approach:
Assuming you have the shader network (sgraph) for your "really cool effects shader", you may very easily add a few nodes and create "normal diffuse" behavior in the same shader. All you need to do then is to Linear Interpolate ( lerp )/ smooth step between the two. Expose the Lerp amount as a shader parameter ( a float between 0.0 -1.0 ) .

Have a look at the lerpcube.sgraph in strumpy shader examples . Instead of two cube maps you need to lerp between your exotic shader and diffuse.

You can also make the transition effect time based. have a look at the time node in SSE or have a Unityscript/c# script set the lerp value of the shader from an update function.


Hope this helps.

 

Has anyone had any luck getting the new version of SSE working in 3.4.2? I am trying to check this out and I can't even install it

 

@Neptune_Imaging: If you want to use SSE with Unity 3.4.2 please use the previous version of SSE version. It's version 4.0a i think . The link should be posted in the forum somewhere.

This last released version of SSE is a Unity 3.5 Preview patch. The only thing that it adds (according to the release notes) is support for directional light maps. If you're on 3.4.2 you wouldn't be able to use directional lightmaps anyways . So why upgrade?
Stramit's being thorough in releasing the entire package instead of an small patch.

As far as I see, that is all. Good luck sir!

FYI: SSE Beta-4.0b seems to work correctly with Unity 3.5 beta.

 

Hey. I'm currently trying to build a lava shader for a small indie game/uni project and got all the other shaders we needed working with this amazing toolkit so far - thanks a lot.

For the lava shader I wanted to get Flowmaps working, a technique that Alex Vlachos of Valve Software showed in his Siggraph paper (here: http://www.valvesoftware.com/publications/2010/siggraph2010_vlachos_waterflow.pdf).

Now I'm running into a bit of trouble: My current setup looks like this:

(Attached is my sgraph).

Now, there's one thing I was wondering about logically and one issue I have technically:
Logically:
On the Assemble Node for the final UV field I'm trying to put in the input on the Y-Axis. But in the Assemble Node I had to set the Y Component to be X as well to work properly?

But that's not an issue that stops me working right now.
More of a problem is the Technical issue: Whenever I have a change of gradient in my flow texture I get a solid color outline that almost looks like a bad jpg compression around the area.

Notice the border around the bars.
I can't seem to get rid of them and since it happens with any kind of texture I think I can assume it's not any compression ugliness.
Am I missing some shader logic here or is that just an issue I'll have to live with? I know this is not so much about the Shader Editor it self than more about general Shader logic but I hope some one knows a good answer to this or maybe even tried to do the same thing before.

Thanks in advance!

 

Thanks I'll give that a shot. Is there a way to cross between three or more textures? (With one of the textures being an animated png or gif)

Also a request.

Would it be possible to have the node description appear in a small window or make it so that it doesn't go away when the mouse is moved?
I know that most people may not have a problem with this, but I use Windows Magnifire and the mouse has to be near the text in order to see it and if I move the mouse near the description, it goes away. It'd be cool to be able to at least hold a certain key down to make the description hang there and on releasing the key, it'd vanish.

I tried just using the PDF, but the editor has a lot more nodes than are listed in the documentation.
Again I know that most people probably don't need that, but I don't think it would be something hard to do.

Thanks again.

 

Alright, I've successfully created my multitexture shader. That lerp example really helped me out.

Now the question is this. Is it possible to have a slider that changes multiple material channels at once? For example the deffuse and normal and specular? or do I have to make a slider for each channel?

Here's my setup?


Now see how just for the deffuse UI have two sliders. one slider from deffuse to deffuse2, and another for Deffuse2 to Deffuse3. Is it possible to create one slider that goes from 0 to 2 where 0 is 1, 1 is texture 2, and 2 is texture 3?

Thanks.

EDIT:
Is it possible to do something like this with a shader?

http://screencast.com/t/sEbyJGaSv1v

Maybe not as detailed, but at least something where it sort of looks like the buildings are rising up?

Is there some kind of clip object I can use to totally hid the buildings from view? Thanks.

ONE LAST EDIT I PROMISE!

Earlier I was asking not if I could use the nodes and make them normal ShaderLab code, but if I could take normal code and turn them into nodes.

I found a particle shader that had a really nice glowing effect on some objects I had, and I'd like to transition from that glowing effect to a solid object.

It was of some buildings with lights on them. With the particle shader, the lights were seen, but the rest was transparent. I think it had to do with how bright the image was. brighter parts were more visible. This made for a really cool effect, but I'd like to transition from that to the normal deffuse texture. If this shader could be turned into nodes, I could probably edit it.

 

et viola :

Not sure how to affect this in SSE. There is a clip example in SSE examples, might be a good starting point. I remember that I saw someone post a rather nifty cutaway shader in the Unity Forum that uses a clipping plane and fills in interior edges. He had not done it in SSE however. For the life of me I can't seem to find out the said post

Sorry I don't think I get you there. In such cases please post the relevant shader so that people have a clear idea of what you wish to achieve using SSE.

There is no 'magic button' that translates shader code --> SSE nodes. Have a look at the logic and do the math using SSE. That's all there is to it. For now I'd suggest more experiments at your end with SSE. Good luck.

ps : It's Diffuse, not Deffuse

 

Cool grills! I've got the nodes working so that one slider controls everything including normal Diffuse, and specular maps. Another one for Gloss. Thanks a lot!

Wow that clip shader is pretty cool. Trying to figure out how to get some different effects in it. I'll keep messing around with it a bit more before I ask about it. I'll see if I can figure it out. These examples are really helpful.

Also just thought of where Node Descriptiosn could go. Instead of just having a comment and settings options in the Node tab, why not have the description there too. As I satated, it is a bit hard to read with the Magnifire on and even though it's a request not everyone really cares about, I think it would be kind of useful and not TOO hard to manage.

Thanks Stramit again for the great Editor. This really opens up some doors for me.

 

Hey guys. I've gotten a nice clip shader that will work. The particle shader I'm wanting to use for effects is this one.

Code (csharp):

1.  
2. Shader "Mobile/Particles/Additive Culled" {
3. Properties {
4.     _TintColor ("Tint Color", Color) = (0.5,0.5,0.5,0.5)
5.     _MainTex ("Particle Texture", 2D) = "white" {}
6. }
7.  
8. Category {
9.     Tags { "Queue"="Transparent" "IgnoreProjector"="True" "RenderType"="Transparent" }
10.     Blend SrcAlpha One
11.     AlphaTest Greater .01
12.     ColorMask RGB
13.     Cull Back Lighting Off ZWrite Off Fog { Mode Off }
14.     BindChannels {
15.         Bind "Color", color
16.         Bind "Vertex", vertex
17.         Bind "TexCoord", texcoord
18.     }
19.    
20.     // ---- Dual texture cards
21.     SubShader {
22.         Pass {
23.             SetTexture [_MainTex] {
24.                 constantColor [_TintColor]
25.                 combine constant * primary
26.             }
27.             SetTexture [_MainTex] {
28.                 combine texture * previous DOUBLE
29.             }
30.         }
31.     }
32.    
33.     // ---- Single texture cards (does not do color tint)
34.     SubShader {
35.         Pass {
36.             SetTexture [_MainTex] {
37.                 combine texture * primary
38.             }
39.         }
40.     }
41. }
42. }
43.  

When placed on objects, it gives a transparent (or semitransprent) effect on objects. I'd like to lerp between that and a solid material. I'm looking on the shader about how to do this, but I'm still figuring things out.

Also, I have a shader that can hold a maximum of nine textures,has some clipping effects (from the clip example) and I want to add the effect this particle shader gives. Would this on a multiple of objects be heavy for the game engine to handle? I mean it might work on my computer, but would others have problems with this? Thanks.

Also how would you create a contrast slider?

I'm guessing it has something to do with subtracting the dark colors while adding the lighter colors or something?

I'm sorry for asking all th questions. Thanks again.

 

So Im trying to create a shader that has wind effects that I can use on my trees and bushes

I have created a float 4 for wind vector and speed and a float for wind strength

is there a way to get world vertex postion and add to that and is there a way to use vertex color to control the wind effect

and I guess a advance question would be is there a way to use the unity wind node to effect the shader

btw the way as an artist awesome thanx so much for this tool

 

Hey, this might be a stupid question that has been covered to death already in this thread, but I couldn't find it so here we go:

I'm trying to make a shader with a custom lighting graph, and honestly the results were a lot simpler then I expected. I was able to implement everything I wanted with the diffuse pass, and the results were great. However, as soon as I added specular information, things got hairy.To do my custom lighting stuff, I multiplied the lighting stuff with the albedo, which worked.


(For this example, I just plugged in the lightcolornode for simplicity. In actuality, that is more complicated).

However, when I try to add specular information to my shader (typical layout of shininess = range and specular = main texture alpha * color) this happens:



I don't want to do anything fancy with the specular, I just want it to act like it would on a default unity shader. How would I go about doing this?

 

Did you solve your lighting issue? I just started diving into this too just to learn... thought about doing a shader similar to MvC3

 

I've figured it out partially. Seems like the preview is wrong somehow because when I export it doesn't look weird like it does in my second image. The only problem is that specularity doesn't appear at all (like the bumped diffuse shader). The specular stuff in the pixel graph is still being calculated because I am multiplying it by my reflection and that aspect works, but the actual specularity itself doesn't. I'm assuming I have to calculate the specularity myself in the lighting graph.

 

Strumpy, if you are reading this, or anybody else that knows the answer to the following questions... please help me =]

Basically I have a cubemap. It works fine for hard/smooth, highly reflective materials like metals, plastics and what not. Now I want to use the exact same cubemap/textures but a lower mipmap level for a more blurry look for the "reflection" so it can be like fake GI on softer/rougher surfaces like skin or cloth. Is there anyway to do this with the current SSE or planned for SSE 2.0?

I did search a bit but I think there is no way to force a certain mipmap level with Unity right now. Is this the case?

If it is not possible, it isnt a huge problem as I can make an extra "blurred" cubemap for the softer materials. But it would have been nice to simply control it with the shader.

So this might be user error, but I can't get this to work in the trial pro version of 3.5b6. When I import it and open the window I get:


ReflectionTypeLoadException: The classes in the module cannot be loaded.
System.Reflection.Assembly.GetTypes ()
StrumpyShaderEditor.NodeEditor.<NodeEditor>m__3B (System.Reflection.Assembly s)
System.Linq.Enumerable+<CreateSelectManyIterator>c__Iterator12`2[System.Reflection.Assembly,System.Type].MoveNext ()
StrumpyShaderEditor.NodeEditor..ctor ()
NodeEditorWindow..ctor ()
UnityEditor.EditorWindow:GetWindow(Type)
NodeEditorWindow:Init() (at Assets/StrumpyShaderEditor/Editor/Scripts/NodeEditorWindow.cs:9)


Am I missing something? It's pro, under windows, but it's also a trial. I didn't think the trial disabled any aspects of the tool though.

 

I figured out the solution to my problem (this is mostly directed at Neptune_Imaging who asked me about this).

There is a preset shader graph called "default lighting" that displays how the typical lighting setup works. I'm thinking that if you want to do custom lighting stuff you should use that as a base and add stuff onto it. Also I would check out the RampLighting preset shader graph and merge it with the default lighting graph if you want a stylized approach like MvC3.

For reference I took a screenshot of the default lighting graph, perhaps someone else will find it useful too.

 

This is good...I've been needing to play around in the lighting graph... and I will definitely play around and see what kind of effect I can get with this...

EDIT: S***...now I have to play around with the default lighting stuff just to get this to work

 

4.5b pinked all of the shaders in my game, most of which I made in Strumpy Shader editor. Is there a compatibility update?

Update- Sorry, incompatible shaders was my first impression but turns out not to be the case. Unity 4.5b's project import is the problem. It nuked every single reference on every script on every object in my project- materials, prefabs, everything.

 

What version of Unity3d are you running?

 

Hey stramit, I have a question for you... I was playing around with the Unity Pro demo and I was wondering if there is a way to get my models to reflect the environment in real time, such as in a render to texture... I just realized that I may end up having to code my models to load up cube maps for the level they are going to fight in, and I have masks in my Gloss textures that tell Unity where to allow the reflections to be... Isn't there a render texture node in SSE? Thanks a bunch :thumbs up:

 

You can just use a regular texture node, and put the render texture into the input just like you would a regular texture.
