What shaders would you guys want?

@Darkmonk,
I'm not the author of that shader but I can give it a go if needed. Can you please post more information about the surface you are using it? Like the mesh in wireframe, texture, etc. Remember this is a vertex blending. If you need more precise controls, you may wanna go with an RGBA mask instead of vertex-based colors for blending.

[EDIT] Looks like Daniel found it. If still not working reply to my post.

 

AWESOME, That fixed it

Thank you so much guys this is exactly what i was after.
also want to say thanks for the offer tatoforever but its ok as its working now

going to give it a good test on one of my models that is already set up just for a proper final test though.
thanks
john

 

Glad it helped!

 

im back lol.

That last shader is working well although now i have found out something i did not think to specify at the start sorry
There is a problem when i try to change the tiling parameter of the indavidual textures, If i change the Black tiling parameter then all the textures tile and when i change the red,green and blue tiling parameters nothing happens I had wanted to be able to tile them independently of each other if possible.
is it possible to have them tile independently of each other with this setup ??

 

Thanks once again dude, your a star got it working perfectly now
you make it seem so easy lol, i need to start learning some basic shader code so i can recognise how to fix these little issues.

thanks

 

Don't have unity pro yet. Still experimenting to see if unity is suitable for my purposes.

 

ripple effect request? or/and splash water effect similar effect when very heavy items throw into water

and i have ask - your custom shadowmap work with free vesion unity tatoforever ?

 

I'll try to extend the current Unity water shaders and add the ripple effect. Gimme few days, I have a hellish amount of work to do in my job (finish our game). ^^

My shadowmapping wont work in the free version as it needs RTs which is only for the Pro version. But I'm working out a nice planar shadows with stencil filtering to give ultra fast realistic and detailed shadows both for the free and pro version of Unity. Coming soon!

 

hi all,
have another little shader request, I would love to have a shader that allows me to paint a dirtmap over my main diffuse texture based on the vertex alpha that ive painted onto my model, but i would like the other colour channels to be kept for vertex colours if that makes sense.

ill try and clarify exactly what im after.
1.Vertex colour information
2.Diffuse texture slot
3.Dirt texture slot (this texture will be multiplied over the diffuse vertex colours and only visible where i have painted some vertex alpha)
if i paint only 50% alpha i would expect the dirt to only be 50% as strong

Will a shader like this work with the beast lightmap or do you need to add something extra to get it to work ? if so it would need it to work with beast as well please.

any assistance with this shader would be awesome,
thanks
john

 

Any luck you might find time to create such thing? It would really help me and my team out, since none of us knows shading.
If you were to spend time on this and you need more info, tell me.

 

Fur/hair shader like they advertise in unity4's videos and dont put it in the assets :S

 

http://forum.unity3d.com/threads/4581-Fur-Shader

 

If i got it right, you need to show vertex colors? May I ask why (just curious)?
Plus diffuse texture and use the alpha channel (of your vertex color) to show a dirt map?
I'm giving it a go.
PS: Yes, it would be compatible with lights, cast shadows and lightmaps.

 

@Darkmonk,
The vertex rgb colors are being blended with the main diffuse colors and vertex alpha defines where the dirt appears. Also, I've added two opacity factors for each textures and a global color for better flexibility/outputs.
I've made a blind guess for the vertex color as i don't have any mesh with vertex color data to try out, so let me know if it works for you.
PS: I would like to see some results on your part (keeps us motivated to work free for the community).
[EDIT] See my next post with the updated shader.

 

I posted a thread about Physically Based Shading that would be cool to try out. Technique used by CoD Black Ops 2.
http://forum.unity3d.com/threads/178933-Physically-Based-Shading

 

Hi Tatoforever,
sorry for the dely in my reply but i was not on my computer much over the weekend so only got a chance to test it this morning.
I think my description was not very good I do not need to see the vertex colours on there own i just need them multiplied into the diffuse texture and then have the dirt texture multiplied onto of the combined vertex colour and diffuse only in the areas where i paint vertex alpha onto my model.
I have made a couple of images and also created what i want in strumpy shader editor as an example although with the strumpy shaders i cant get them to work with the beast lightmaps and im not sure how efficient stumpy shaders are so i only use strumpy for example shaders.

attached is a basic scene with an example object and texture to show the rough idea of what i need it to do, ive also included an image of the strumpy graph so you can see what i did.

Hope this helps.

Yeah ill post any cool images of work ive done that use these shaders as i do really apprieciate the help from you guys to make these shaders for free

View attachment $DirtBlendScene.unitypackage

 

Alright, I'll give it a go.

 

Here: View attachment $Detail-Diffuse-Vertex-Colors.shader
Works with lightmaps, lights and even shadows.

 

Dude, your a star this is exactly what i was after
Thank you and ill try and post some images of how i use it once i get some levels built using it

 

Looking forward to your images!

 

Hey,

I'd like to have an Unlit Shader with a blurred outline. It's kind of like the shader in Highlight System but not visible behind other object and not affected by lights. For properties it would be nice to have MainTex, Range and Outline Color!

Thank you so much if you can do this!!

 

Such effect can't be done in a single shader. It's an entire post-effect and requires Unity Pro because of the use of RTs.
HighlightSystem doesn't do any sort of lighting, it just write to the depth buffer (selectively) and blur it out in an extra pass.
Re-writing such system myself will take lot of time, if you can buy it i can modify it and customize it to your needs.

 

Hey, thanks for the reply! I already bought it and I think I can modify it myself to achieve what I was talking about, but I find it kind of a big system only to do that. That's why I asked you to make it in a shader, but looks it can't be done that way

Another question, what do you think about the strumpy generated shaders? do you think it's good enough to use as a final shader in a game or should it be rewritten clean?

 

Yeah, post-process effects that requires that uses/does depth stuff, RTs, etc are in most part a little big. Most of the time they have multiple shaders and scripts. But still, I can give it a look (send them privatelly) and I'll make the changes for your needs.

As for the Strumpy Shader Editor: It's a bit outdated (last version dates back of March 24th 2011). Though I don't work with but have taken a look at what it generates and it add lots of unneeded stuff to the shader. Shaders needs to be cleaned a bit. I can't tell you if you can used for final production products but at least prototype stuff should be fine i guess.
I write such effects by hand (in Cg programs or CgFX shader language) maybe someone with real experience of the strumpy editor will answer that question better than myself. Perhaps Tim (strumpy shader editor's author) is near and can help you with that question?

 

HBAO!

 

Hi is it possible using a shader to convert a texture that looks like this



and make it look like this

 

Yes. Sample the texture from a few different points around the current one and if the range of colors is significantly different, make it black. Otherwise make it white.

 

As 747823 said, this is relatively easy to make.

 

http://forum.unity3d.com/threads/70585-Skydome-for-unity3D-3-x

hi again

u can improve realistic this day/night scattering shader when u have free time? (version 2.1 and request for improve sunset and sunshine quality majority) if no i think i realse improved this package (majority enh is change&simplify code c#) soon

i will added random cloud so u haven't to improve cloud

 

I don't see any problem with this package, I've adjusted few things in the scene to make it working fine.
Here: http://www.fileconvoy.com/dfl.php?id=gcaa93731e4a9abfd999280445815d0966877ae47a

 

747823 and tatoforever, thanks for the giving me some hope.

I have not attempted any shader coding before. I did find a binary shader in the wiki - but it will not run on Unity 4 so I cannot tell if it will do the job or could be used as a starting point.

http://wiki.unity3d.com/index.php/Binary

Any takers on porting that up to Unity 4 or writing something from scratch?

Thanks

iByte

 

Hello iByte,
I'm giving a look at the shader you've want it to work on Unity4. Do you need lighting calculation on it?

 

Hi tatoforever,
My first inclination would be to say no (not for the images I am initially going to be supplying ) ... but after watching the utube video it looks like lighting support might give better results in some cases, If I was to use the shader on a player supplied artwork/photo for example

Thanks

iByte.

 

Here: View attachment $binary.shader

Changes: Complete re-write of lighting functions, works with Unity 3.5/4.x
If isn't much to ask I would like to see some results on your end with the shaders we provide.

 

Hi, Tatoforever,

Here is a link to some samples. I have not tried any lighting yet other then a single directional light. Would it be possible to thicken the resulting lines?

 

Ok, tomorrow at the office I'll give it an other quick spin. Have you tried tweaking the properties? Btw it works with any sort of light (not just directional) and It's vertex based.

 

Hi tatoforver, I experimented with some of the settings and was able to get a heavier outline by doubling the modulus number. I think a small improvement would also be to change any white pixels to black if pixels on both sides of the white pixel were black?

https://dl.dropboxusercontent.com/u/2238318/Unity/SavedScreen 1.png

One other request, for a final pass can all the white pixels be made transparent?

Thank you very much for the work you have put in so far!

iByte

 

The second pass is when there's no light affecting that mesh (otherwise the mesh will look entirelly black). But I can make a secondary version with transparent pixels on the white colors (color1) in the second pass. Is that what you want?

 

Hi tatoforever,


I think so

This is an example of what I am trying to get as close to as possible.

tatoforever,

I was wondering if you could show us how to create a transparent shader which renders the depth of an object by subtracting the distance from the camera to its rear surfaces and the distance from the camera to its front surfaces? This would be a great starting point for a volume shader, however I just can't really figure out how to set up a Multi Pass/Replacement shader like this.

Any help would be really appreciated. I just need to get started so I can understand these kinds of shaders, then it opens a whole new world for me...

Thanks.

 

@ sgoodrow and the rest of guys requesting help:
I was quite busy the last days but I'll take some time this weekend to answer and complete your requests!
Sorry for the inconvenience!

PS: If you really need to poke me out for something ultra-urgent, please write me an email directly to:
tatoforever [at] psychozinteractive [dot] com

 

Yeah I was wondering about / hoping for one like that too.

 

Hello, link is dead, can reload it? Thanks

 

I was wondering, whether it's possible to make a shader that would generate on run a texture looking much like this:
http://libnoise.sourceforge.net/tutorials/images/newheightmap.jpg
from this tutorial:
http://libnoise.sourceforge.net/tutorials/tutorial3.html
I've got it working on CPU, but it's way too slow for my needs - so I was thinking about rewriting it for shaders, but, sadly, I know nothing about writing them
I'd be very grateful if you'd push me in the right direction of writing this, even if you could not find spare time to write it yourself.

 

Hey guys, I didn't read all the posts so forgive me if this was answered but -> was the water shader ever started/completed?

 

I have a quite simple request (i hope : p):
A fast billboard shader that renders a specific texture as a billboard and with alpha blend?

 

Hey guys,
I'm trying to get some free time this week (again) to workout your requests.
Thanks for being patient.

 

I'll throw this one out there and see if anyone has anything.

I'm looking for a shader which I can apply to a mesh, which will make the mesh into a volumetric fog zone.

The idea is to create foggy areas around the level.

 

I was actually thinking about doing this already, but I don't think it can be done with shaders alone...

The way this is done is that you first render the depthmap of everything plus the backface of your volume. In the next pass you then sample this depthmap to figure out how deep the fog is at that pixel.
