Standard shader with vertex colors

I tested this one but normal maps not working? or that just me?

 

Hi,

I tried version 0.92 and while I get it working on 5.5 using workarounds mentioned before, there are new problem in 5.6b4.

Error I get is:

Shader error in 'Standard (Vertex Color)': invalid subscript 'tangentToWorldAndPackedData' at Assets/UnityVC/UnityVC.cginc(149) (on d3d11)

Compiling Vertex program with DIRECTIONAL _VERTEXCOLOR_OFF
Platform defines: UNITY_ENABLE_REFLECTION_BUFFERS UNITY_USE_DITHER_MASK_FOR_ALPHABLENDED_SHADOWS UNITY_PBS_USE_BRDF1 UNITY_SPECCUBE_BOX_PROJECTION UNITY_SPECCUBE_BLENDING UNITY_ENABLE_DETAIL_NORMALMAP SHADER_API_DESKTOP

 

Okay, I fixed it and got it working for versions for 5.5 and 5.6b (or at least it seems to be working)

If someone needs them. I can post them here or somewhere

 

Thanks Masolnar, that would be great if you could post things when you get them working!

I can't test it myself yet. I've still been on 5.3.5f1 because I just need to get more code written, I don't think the newer versions add much I need and Unity keeps breaking the shader.

I do download the latest for use in the future, I do expect to move up my version eventually.

Thanks!

 

Both files can be found in https://gist.github.com/H-man/d5cc76afd930f90dc18b06e69cd9f503

For 5.6 version I had to change:
half4 tangentToWorldAndParallax[3] : TEXCOORD2; --> half4 tangentToWorldAndPackedData[3] : TEXCOORD2;

and also needed to add float4 posWorld : TEXCOORD8; in VertexOutputForwardAdd_VC struct

 

Thanks!

 

I can't make it work on 5.5. several hours in. Had anybody any luck? The shader above doesn't compile, and I cant fix it.

 

Can you post the error message and shader code? Maybe I can help..

 

Just to follow up on @Tzan's point that @Coredumping is using the standard shader with a couple of small mods - this is currently working for me on 5.5.

Code (CSharp):

1.  
2.  Shader"Custom/VertexColor" {
3. Properties {
4.  _Color ("Color", Color) = (1,1,1,1)
5.  _MainTex ("Albedo(RGB)", 2D) = "white" {}
6.  _Glossiness ("Smoothness", Range(0,1)) = 0.5
7.  _Metallic ("Metallic", Range(0,1)) = 0.0
8.  }
9. SubShader {
10. Tags { "RenderType"="Opaque" }
11.  LOD 200
12.  
13. CGPROGRAM
14. //PhysicallybasedStandardlightingmodel,andenableshadowsonalllight types
15. #pragmasurfacesurfStandardfullforwardshadows
16.  
17. //Useshadermodel3.0target,togetnicerlooking lighting
18. #pragmatarget3.0
19.  
20. sampler2D _MainTex;
21.  
22. struct Input {
23. float2 uv_MainTex;
24. float4color : COLOR;
25.  };
26.  
27. half _Glossiness;
28. half _Metallic;
29. fixed4 _Color;
30.  
31. void surf (Input IN, inout SurfaceOutputStandard o) {
32. //Albedocomesfromatexturetintedby color
33. fixed4 cc = IN.color;
34. fixed4 c = tex2D (_MainTex, IN.uv_MainTex) * cc * _Color;
35.  
36.  o.Albedo = c.rgb;
37. //Metallicandsmoothnesscomefromslider variables
38.  o.Metallic = _Metallic;
39.  o.Smoothness = _Glossiness;
40.  o.Alpha = c.a;
41.  }
42. ENDCG
43.  }
44. FallBack"Diffuse"
45. }
46.  

 

Thank you!

There is an error:

I'v imported 0.92 version and replaced UnitiVC with one from your github link (5.5 one)

 

Strange. I think it must be some of those #ifdef:s around lines 263 - 288 that are defined different in your project.

I attached my test project that works on my machine at least.

 

Thank you! I managed to get it working by changing 299 line from

Code (CSharp):

1. #if UNITY_SPECCUBE_BOX_PROJECTION

to

Code (CSharp):

1. #if UNITY_SPECCUBE_BOX_PROJECTION || UNITY_LIGHT_PROBE_PROXY_VOLUME

But new problem arrived. I need that shader to fade away over time ejected gun shells particles. And they really do become transparent.
But in fade (and transparent) mode meshes loose their ability to recieve shadows, so they shine in a shadow.
I have no experience in shaders, so question might be plain dumb, but - Can it be helped?

 

Hi, defaxer,
Thanks for the great shader first However, when I was importing it to Unity 5.5.0f3, it reports such error:"Shader error in 'Standard (Vertex Color)': 'MainLight': no matching 1 parameter function at Assets/Shaders/UnityVC/UnityVC.cginc(125) (on d3d11)"

Since I am new to Unity, do you know why it report this error?

Thanks

 

Hi! Look for an attachment from couple posts above by @MasoInar . It fixes that error. And you could apply my one-line patch from above too if something won't work..

 

Hi, thanks for the suggestions. I have used UnityVC.cgnic in https://gist.github.com/H-man/d5cc7...f503/bff05d6dc6f671799c750c45b4e9b8032aa77a0d
However, it still reports this error "Shader error in 'Standard (Vertex Color)': invalid subscript 'posWorld' at Assets/UnityVC/UnityVC.cginc(299) (on d3d11)" :-(

 

2 posts above is the solution that solved that error for me.

 

i have unity 5.5.1f1 and i get this error

Shader error in 'Standard Specular (Vertex Color)': invalid subscript 'posWorld' at Assets/UnityVC/UnityVC.cginc(299) (on glcore)

Compiling Vertex program with DIRECTIONAL SHADOWS_SCREEN
Platform defines: UNITY_NO_SCREENSPACE_SHADOWS UNITY_ENABLE_REFLECTION_BUFFERS UNITY_PBS_USE_BRDF2 SHADER_API_DESKTOP UNITY_HARDWARE_TIER3 UNITY_COLORSPACE_GAMMA

i have import version 0.92 and replaced UnitiVC with one from github link 5.5!

UnitiVC already has #if UNITY_SPECCUBE_BOX_PROJECTION || UNITY_LIGHT_PROBE_PROXY_VOLUME

at line 298

 

Worked perfectly. Thanks

 

Hi
I am trying to make a simple project just to get an understanding how to color the surface on a mesh in unity.
I work as a developer and have been doing C# development for 8 years and want to learn how to work with 3D graphics.
I have been trying to just make a project where I can use vertex coloring to set different colors on the sides of a cube, but haven't had any success. I have tried all the file and projects in this thread, and anything else I can find online, but haven't been able to get any of them to work in Unity 5.5.
Except for unityVC_test_550f3 which worked until I tried to move the shader and material to be able to use it on my cube, then I got a bunch of errors I have no idea what they means.
I have been trying to get my head around how this works for months now, but still haven't really made any progress.

Could someone please point me in the direction of a good sample project or tutorial if you know of one?
Or could someone that understands this stuff, please make a really simple project for me with a cube with a color array that sets the vertex's to give different sides of the cube different colors.

 

on UnityVC.cginc remove this || UNITY_LIGHT_PROBE_PROXY_VOLUME from line 298
also comment all the block / function from lines 363 to 411

 

Hi, I made super simple unity project with two simple vertex color shaders (lit and unlit) and script that allows you to set different colors to top, bottom and sides of the cube at runtime. It might be too simple for your needs, but hopefully you get the basic idea of setting vertex colors

https://github.com/H-man/SimpleVertexColors

 

It does not work in 5.5.

 

Anybody figure out how to get this building on Android or iPhone. Everything works fine on the PC, but when I build to test on my android phone, materials turn pink. Please feel free to point me to the solution if I missed a comment on this thread. Thanks Masolnar.

 

Hi, I got it working on Android (tested on editor and actual device) and made a github repo for you, but it's for unity 5.6.0f2. I Hope it helps. I don't currently have any IOS device, so I can't test with that.

Hey I'm using Unity 5.5.3f1 and getting this error

invalid subscript 'posWorld' 'FragmentSetup': no matching 5 parameter function
Compiling Vertex program with DIRECTIONAL
Platform defines: UNITY_ENABLE_REFLECTION_BUFFERS UNITY_PBS_USE_BRDF1 UNITY_SPECCUBE_BOX_PROJECTION UNITY_SPECCUBE_BLENDING SHADER_API_DESKTOP UNITY_COLORSPACE_GAMMA

I did all the changes to the code on this post, but since I started to use shaders this week I don't know how to fix this error.
Thanks for the help

 

I could Kiss you! But I'll just thank you immensely!!!!

 

Thanks !

 

Hi guys. This looks pretty cool but I couldn't use it in Unity 5.5.1. It says:

Shader error in 'Standard (Vertex Color)': 'MainLight': no matching 1 parameter function at Assets/Shaders/UnityVC/UnityVC.cginc(154) (on d3d11)

I am not sure how to resolve this problem

 

So I started using
Unity 5.5.2f1
StandardVC.shader v.91
UnityVC.cginc v.92.1

Not using a Metalic texture works fine.
When I add texture, the R channel interacts with the normal map wrong, highlights are hitting in wrong ways.
The Alpha channel seems to be ignored entirely.

I could provide images if someone was interested.

I tested my texture with the Unity Standard shader + cube, alpha is there and works fine.

 

Works like a charm for me. Thank you so much everybody who made this possible!!!

 

nothing works in latest unity

 

Hi, just upgraded and tested with unity 2017.1.0f1 version and seems to work fine (at least on mac). If you want to test it, here's the repo: https://github.com/H-man/UnityVertexColors/tree/unity2017

 

Great job! i just tested it i was also using 2017.1.0f1, and working on a webgl 2.0 port of my android game. and it works in chrome!

 

incase you wanted to see Masolnar's updated shader in action, http://realdefinition.net/play/

 

While this does work nicely, the colors are incorrect when working in linear space. I'm no expert but changing the vertex shader outputs from o.color = v.color to something like

Code (CSharp):

1. #ifdef UNITY_COLORSPACE_GAMMA
2.     o.color = v.color;
3. #else
4.     o.color.rgb = GammaToLinearSpace(v.color.rgb);
5.     o.color.a = v.color.a;
6. #endif

should handle it?

 

Thanks guys, this is the only Shader i ever needed. If i make some money from my game I will Donate some money. Thanks again

 

I got a problem with this shader. Im assigning it at runtime and its vertex properties wown't work unless i expand the material in editor. now i found this in script ref https://docs.unity3d.com/Manual/MaterialsAccessingViaScript.html
and i have enabled everythining i could but i can't find how to enable vertex. Anyone knows how to enable it?

 

if you add the vertex colored to your model in either c# code, or in the modeling program, it will give your 3d model vertex coloring.

I do both. I set some things in my 3d program to be a certain vertex color per object.

And in the case of that link i gave, i use code to assign house colors, and even in the map editor i low editing users to color the house. All using vertex color.

 

Hi,

I am on Unity 5.5 and get this error message:

Code (CSharp):

1.  
2. Shader error in 'Standard (Vertex Color)': invalid subscript 'posWorld' at Assets/Shaders/UnityVC/UnityVC.cginc(299) (on d3d11)
3.  
4. Compiling Vertex program with DIRECTIONAL _VERTEXCOLOR_OFF
5. Platform defines: UNITY_ENABLE_REFLECTION_BUFFERS UNITY_PBS_USE_BRDF1 UNITY_SPECCUBE_BOX_PROJECTION UNITY_SPECCUBE_BLENDING SHADER_API_DESKTOP UNITY_COLORSPACE_GAMMA
6.  

I replaced UnityVC.cginc code by the one from Github by MasoInar...

Can anyone help?

 

Same for me on Unity 5.6.2f1 anyone have ideas ?

 

These generally only work in the version it says it works with.
There is no guarantee it works on any other version.
I'm still on 5.5.2 because the version I'm using sort of works but not fully.
Read my post from June.

 

Quick update, I just updated to latest stable unity (2017.1.1f1) and tested vertex colors shaders. Everyhting seems to work fine and without any errors.

If you want to check it out, I also updated the codes to github and moved everything to master branch. I made unity5.6 branch for backup, but I can't currently test or fix problems with that version.. Sorry about that.

Edit: link to git: https://github.com/H-man/UnityVertexColors

 

The link above to the GIT is broken.
But I found it anyway

If you made changes to the important files you should probably update the comment notes at the top to mention the version its been adjusted for and/or currently supports.
I'm not sure if the current comments are accurate.
.shader
.cginc

Thanks for the support!

 

Just updated VC shaders so GPU instancing can now be enabled like in default standard shader. Also tried to find and update those comments in .shader and .cginc files

 

Why do vertex coloured shaders look washed out in linear colour space, I really need the vertex colour one for my particle system but have to use gamma colour space which looks terrible

 

Just a shout out to Masolnar for the top work keeping this asset alive. Thanks mate!

 

Hi, I tested those shaders with linear and gamma mode and yes, the results look different. It might be the different blending that causes this (see: https://docs.unity3d.com/Manual/LinearRendering-LinearOrGammaWorkflow.html)

Anyways I updated and tested the shaders with Unity 2017.2.0f3 and all seems to work fine. I also attached the screen shot where you can see that in linear color space the colors are not so bright and vibrant, but maybe you can 'correct' those with post processing?

 

Hello everybody, sorry for the noob question but how am I supposed to use this latest version?

The first version came as an unity package, the one available on github is a unity project, Ive tried to import the shaders and it asked for the UnityVC file, I`ve imported it and now its asking for the editor file, pretty sure it will ask for something else after this. How can I import the necessary assets to another project?

thanks in advance, and Masolnar, thanks for sharing this content, Its really helping me out

 

Could you just copy the UnityVC folder in your project's asset folder? You can delete that example scene, fbx and textures if you want.

 

Hi.

@Masolnar I've downloaded your 2017.2.0 version and the shaders give me "Can't find UnityVC.cginc" and "UnityVCShadow.cginc" errors, even after importing the CGIncs first. The shaders can't find them. What can I do?

Thanks.

EDIT: Never mind, I imported it wrong: I copied the UnityVC folder into Assets then moved everything to the folders I made, worked great. Sorry for the bother!
