Shader Forge - A visual, node-based shader editor

I have opened yet another new project, uninstalled Unity and reinstalled the latest version, downloaded and installed SF and still the same problem.
I feel like I now have a series of shaders I have made and a completely useless project now as I can't really do anything now.

 

Maybe @Acegikmo has some idea. Might be a bug, but it seems pretty isolated to something on your machine/version of SF or something, no one else has mentioned similar problems and I can't reproduce it. Sorry

 

@RogueCode See my post about post effects on the SF forum - http://neatcorporation.com/forums/viewtopic.php?f=6&t=383

You have to open up your shader code and manually delete the "Meta" block of code. Someone mentioned adding the EnableCameraDepthInForward.cs component to your camera might fix it, but I haven't actually tried that yet.

Deleting the meta block fixes the black screen though. You'll have to do this after every change you make in SF.

 

@PeteLaChatte Yep that's totally doable. Not sure if there's any tutorials out there though, but it should be easy enough by just modulating the vertex positions with some noise/waves.

 

@DMeville Thanks so much for the quick reply! That indeed fixes it
Is the default post-effect meant to be upside down or have I done something else wrong?

 

@RogueCode I don't think it should, but you should be able to flip it. Try this: Plug the UV Coord.v -> One Minus. Plug the UV.u and One Minus into an Append and plug that Append into the Remap.

Not sure if having the post effect upside down will cause issues later though, not sure why it would do that.

 

Could I use shader forge to do stereographic projection (https://en.wikipedia.org/wiki/Stereographic_projection)? Trying to achieve a tiny planet style effect. Im messing around right now but its currently just rotating the UV's in an odd way.

 

Can you share nodes tree?

 

@DMeville

About ShaderForge, I think that a new version it's necessary (last version was released 3 months ago), but @Acegikmo must still release something

 

Thank you, that worked
Still have no idea why it happens, but it works for now.
EDIT: Just found something interesting. Only the _MainTex is flipped, a second texture is fine. So I just flipped the UV's of the texture input node.

I was getting sick of having to remove the meta pass from the shader on every modification so I made a quick editor script that you might find useful too.
It will add a menu in Tool > Remove meta pass from shader and you just need to hit go each time you want to remove the pass from your shader.
(hacked together and not well tested btw)

Code (CSharp):

1. using System;
2. using UnityEngine;
3. using System.IO;
4. using UnityEditor;
5.  
6. public class RemoveMetaPassFromShader : EditorWindow
7. {
8.   Shader _selectedShader;
9.  
10.   [MenuItem("Tools/Remove Meta Pass from shader")]
11.   private static void ShowWindow()
12.   {
13.     GetWindow(typeof(RemoveMetaPassFromShader));
14.   }
15.  
16.   void OnGUI()
17.   {
18.     _selectedShader = EditorGUILayout.ObjectField(_selectedShader, typeof(Shader), true) as Shader;
19.  
20.     if (GUILayout.Button("Go"))
21.     {
22.       var path = AssetDatabase.GetAssetPath(_selectedShader);
23.       var shaderText = File.ReadAllText(path);
24.       var lastPass = shaderText.LastIndexOf("Pass {");
25.       if (!shaderText.Substring(lastPass).Contains("Name \"Meta\""))
26.       {
27.         Debug.Log("Looks like there is already no meta pass.");
28.         return;
29.       }
30.       var openBrackets = 1;
31.       for (var c = lastPass + 6; c < shaderText.Length; c++)
32.       {
33.         if (shaderText[c] == '{')
34.         {
35.           openBrackets++;
36.         }
37.         else if (shaderText[c] == '}')
38.         {
39.           openBrackets--;
40.  
41.           if (openBrackets == 0)
42.           {
43.             var metaPass = shaderText.Substring(lastPass, c - lastPass + 1);
44.             shaderText = shaderText.Replace(metaPass, String.Empty);
45.             File.WriteAllText(path, shaderText);
46.             break;
47.           }
48.         }
49.       }
50.       AssetDatabase.Refresh();
51.       Debug.Log("Removed meta pass successfully.");
52.     }
53.   }
54. }
55.  

 

I guess this should be kinda simple but.... how to make something like this?

 

@daville check out the toon shader in the example scene. that should give you a start

 

Here's a demo of the fuzzball where you can play around with the colors and alpha. I used the free Color Picker UI asset for the color selection. If the color picker gets glitchy, play with the sliders and click apply.

Sorry to jump back to this again, but is there any way of attaching something like this to the camera with transparency?

 

I have a seat for version 1.08 however, I can't update to the latest. After the switch to support unity 5 do I need purchase a new licence?

 

You may need to install a newer version of Unity. Not all plugins will be available in their latest updated form on older versions of Unity.

 

how to use both uvtile node and rotate node for atlas ?
may be there are some bug when use uvtile and then rotate ,the result is wrong.
any help?
Would anyone know how to do both rotating and then offsetting the UV's? I'd be much appreciative of anyone's help!

 

Does anyone know how to use the Post Effects shader preset, what do I do with the shader to get it on the camera?

GUYz pls help me..........
i need make the crystal glow inside the glass spear using shader forge

 

Does SF come with translucency support (seeing light through leaves for example, or light through quartz)?
If so, does anyone have an example of this working with sub-surface artifacts?

 

Hi, how i can control shader forge slider parameter over life time in shuriken particle system. In UDK there was something like dynamic parameter module for doing this. How can i do this in unity ?

 

@elizeusz Scripting. The specifics i don't quite know though you'll have to look at the particle scripting docs to hook up things like this. http://docs.unity3d.com/ScriptReference/ParticleSystem.Particle.html something like lifetime might help you here

 

If you don't need vertex colours on the particles, read one of the vertex colours in SF and use that to power your slider. Then in the shuriken particle editor edit the "colour over lifetime" gradient to however you want the slider to animate

 

Thank You i will try both and see which one is the best

 

Using the triplanar example (First Image), is it possible to cover each tile over a 2-unit area instead of 1?

My this I mean have the texture spread over 2 units per tile instead of 1?

Also, the texture stays where it is when the object is moved? Is there any way to remove this?

 

@Labyrith Studios http://neatcorporation.com/forums/viewtopic.php?f=6&t=8

It sounds like you also want to scale up your texture. On the material inspector on the texture there's a "tiling" param. By default it's set to (1,1), if you want the textures to be twice as big change it to (0.5, 0.5)

 

Start with a custom lighting graph. Mess with Light Attenuation; remap it from (0-0.05) to (0-1) and clamp that. That'll get you black and white solid lighting (no falloff).

The other thing you want to look into is the Unity post effect called Edge detection. Make a copy of it you can mess with. Maybe instead of black lines on a white background multiplied over the view, you want white lines over black, added to the view?

You can choose a rotate-around-this-point input for the rotator. You will need to adjust this based on what tile you're using.

You'd want to to the atlasing first, then clamp to that tile (important here, so you don't get bits of the neighbouring tiles when you rotate).

Then find the center of that tile in UV position (for a 2x2 tile sheet, the top left would be 0.25, 0.75), then rotate around that maybe.

You guys are both looking for sorta the same thing here I think.

The best bet would be to use a custom lighting model, and to turn double-sided on.
There's some Light Wrapping and other lighting options, check the shader forge (what does this node do) website; just right click on a node in SF in Unity and you'll find it. The examples are right at the top. Also check the first page of this thread.

Other things you can do are to (again, using a custom lighting model), change from the default Normal(dot)LightDirection. You can do that, and negate(Normal)(dot)LightDirection, and that will get you backface lighting.

Other things to consider are not doing any Normal-based lighting at all. If you replace N.L in a SF node graph with a value of 1, and rely solely on light attenuation and color, you get what sorta looks like fog or smoke or a very fine or hazy jelly. Go on youtube and look for SF Custom Lighting tutorials, you'll know it when you see it.

More advanced things, like rendering an inside-out ambient occlusion map (invert normals, bake AO), will get you basically a jello-thickness map; where the black areas will transmit the most light 'through', and white areas will get only lit from the side you're viewing it from because it's too thick to see any light on the other side.

If possible, try to maintain some semblance of physically based, good-looking-in-all-conditions rendering, and you'll likely have to work the specifics of that out yourselves.

The easiest way to do this is if you have a particle that fades in for the first 10% of it's life, then fades out over the last 10%. That way, you can animate alpha over lifetime to be (0) at birth and (1) at death, and, in shader forge, you can grab vertex alpha, then remap Vertex.Alpha from (0 to 0.1 into 0 to 1), and (0.9 to 1 into 1 to 0), lerp between those by Vertex.Alpha, and clamp the result. Send that into the transparency input. That's fairly easy, and by getting Vertex.Alpha anywhere else in the shader, you have the particle's age (from 0-1).

 

Divide worldposition (presumably all of it, but you can do individually XYZ if you want) by 2.

If you want the texture to 'move' with the object, instead of using world position, use object position.

Please help.

 

I have no idea what you're asking for. My guess that's why no one else has answered, as well.

Be more specific about what you want to do.

 

Hi,

I was hoping that someone would set me on the right track to translate this dome/barrell/fisheye shaders. Somewhere my translation and graphs aren't resolving:

http://www.geeks3d.com/20140213/gls...nd-barrel-distortion-post-processing-filters/

or

http://adrianboeing.blogspot.com.au/2011/02/sphere-effect-in-webgl.html

 

@bigSky http://eat3d.com/free/ue4-shader-fx-cubic-lens-distortion this might help you. though some node may have different names

 

Sorry to bother you, but I tried to attach this to my main scene to test with my character controller, and my player walks right through it, not passing through it as a portal would but passing physically through the face.
I also have an issue with movement, where the border of the portal being rendered in the frame (the red frame if looking through the blue for example), jitters when moving as if it isn't being updated as often as the camera.

 

Is ShaderForge supposed to be compatible with 5.4 beta maybe? I am running on 5.4.0b6 and it doesn't work with any project (including an empty new one). Sometimes it will crash right after the shader has been loaded, and sometimes it doesn't crash but no mesh is displayed in the preview window (skybox does get displayed, but none of the meshes, including sf_meshes. I know 5.4 is beta and no plugin is expected to support beta versions of Unity , just checking out if anyone else has this problem, and if there is a fix to this...

 

I got a interesting Shader for UE4. Below is the Shader tree. I want to convert it to unity is it possible?

and the link to the post is here

Stuck with Mask(B), Object Bounds and Param(0.5) nodes.

Edit: it fakes fluid in a container

 

@Eideren Hi, I've found your version of a parallax shader for shader forge on page 50 of this thread.
It works very well, though I have to invert my heightmap for it to show correctly.
Is there a way to adjust your code block so I could avoid inverting my heightmap?
Currently lighter values go inwards and darker values go outwards, it would be amazing if this would be vice versa.
Hope you can help me out. Thanks.
B0kkie

 

Well, how would you go about changing values from 0=>1 to 1=>0 ? You would do a simple 1-value, right ?
Well, you can do the same thing here, for both lines starting with "float tex = tex2D(..." you can change it to "float tex = 1.0f-tex2D(..."

 

Thanks, that made perfect sense. Working like a charm!

 

Anyone know how to actually attach a "Post Effect" shader to a camera?

 

@Labyrith Studios http://neatcorporation.com/forums/viewtopic.php?f=6&t=383

 

I think Param is just a Value node, Mask would be Component Mask and I think you'd have to bring in Object Bounds yourself.

 

Thanks Obsurveyor
here is the node tree but not able to connect clamp to opacity.

 

@dMobiLab You missed the Component Mask (B) on your World Pos - Object Pos!

The reason you can't connect is because you're trying to plug in a three channel output into a one channel input (opacity), and it doesn't work. You can see how many channels you're using per connection by the number of lines between the nodes. What the component mask does is it allows you to extract one (or more) channels individually. In this case both the channel masks in the UE4 Graph are masking out the B channel, so if you click the - beside the R on the bottom of the component mask you can choose the B channel and use that. You can also right click on any of the nodes and click "What does <node> do?" to bring up the docs for that specific node!

 

Thankyou @DMeville
Able to create the Shader (still buggy but works fine for our project)

Shader Tree

 

Hi, don't own shader forge and i was wondering if it has moved to GGX shading model?

 

Hi,

I have some problems replicating the fog shader to ShaderForge from here:
http://www.iquilezles.org/www/articles/fog/fog.htm

namely this one:

Code (CSharp):

1. vec3 applyFog( in vec3  rgb,      // original color of the pixel
2.                in float distance, // camera to point distance
3.                in vec3  rayDir,   // camera to point vector
4.                in vec3  sunDir )  // sun light direction
5. {
6.     float fogAmount = 1.0 - exp( -distance*b );
7.     float sunAmount = max( dot( rayDir, sunDir ), 0.0 );
8.     vec3  fogColor  = mix( vec3(0.5,0.6,0.7), // bluish
9.                            vec3(1.0,0.9,0.7), // yellowish
10.                            pow(sunAmount,8.0) );
11.     return mix( rgb, fogColor, fogAmount );
12. }

Here is my node tree and SF settings:

Spoiler: nodes

This is my scene, and as you can see the effect stays blue even when I'm looking at sun:

Here is a reference of how it should look like:

Any help appreciated!

 

Anyone know of a way to setup a random picking system?
I want to have a grid system of 2 units to a tile (instead of the default 1 unit) and set a random set of textures to each grid place.

An example of this would be Portal 2, where the walls were textured using random grids that used a series of textures and placed them randomly around the grid depending on it's size.

 

This is easy enough.

There's a noise function in SF, which can be used for this. Take your worldspace coordinates like you would for any other triplanar mapping shader, and, use the FLOOR node on each X, Y and Z, append two of them at a time (XY and plug that into the NOISE node. Lerp between XY, XZ and YZ like you would any other triplanar shader, and output that to emissive.

You should see solid-colored grayscale squares on the walls, floor, etc. You can scale these like you would scale the textures on a triplanar shader divide worldspace by 'texture size in meters'.

The final step is to take an atlas of tiles (say 4x4) and work out a way to select between them using that noise. Look into the UV atlas node. Remember, the grayscale noise is from 0-1, so if you need 1-16 (in a 4x4 sheet) just multiply the noise by 16.

Bonus points if you alter the UVs of some tiles as well, by mirroring them left-to-right for the walls, or rotating them for the floor tiles, also based on the noise.

 

I have managed to set this up relatively well.

I have the noise set up correctly (I think), and have worked out how to "atlas" textures (a lot of trial and error), but I cannot work out for the life of me how to get the last bit working, where the textures are selected by the noise.

I am hoping @Acegikmo or someone else may have an idea on how this can be done.

P.S. My atlas is also a few pixels out (I can see small lines of the other tiles but I think this is just the texture not being perfect).
