Transparency sorting issues and Blend DstColor Zero.

I am trying to have multiple sets quads rendering black values and multiply that with the rest of the rendered frame. The only way I have found to have the quads blend together is turning ZWrite Off, introducing a new issue of objects sorting in front of it. If ZWrite is on, no blend occurs, and the whole quad occludes.

Code (csharp):

1.      Tags {"Queue"="Transparent" "IgnoreProjector"="True" "RenderType"="Transparent"}
2.      Blend DstColor Zero
3.      ZWrite Off

 

Sounds like the material custom queue issue to me. Since Unity 5.0 if you set a shader on a material then change that shader's queue, the material ignores those changes. This is because the default behavior for Unity is now to set the material's custom queue to something which then overrides changes to the shader. To fix this you can change the shader on your material to something else and back, or you can right click on the inspector tab, select debug, and set the custom queue to -1, the default value prior to 5.0 that means "use the shader's queue".

Thank you, works like a charm, I was not aware of that change.
