Text mesh (font material) renders on top of everything, any way to change that?

Question

I have these objects with some text on them floating in my space (labeling things as it were). My problem is that apparently, text is drawn last, so it is visible always, even if it should be occluded by intervening solid objects. Is there a way to fix that? Do I have to muck with the shader on it?

Yes, you have to use a different shader. Here's one to start with:

The link is now broken. Can someone post here the shader? Thank you very much.

The shader has been moved here: http://wiki.unity3d.com/index.php?title=3DText

     Shader "GUI/3D Text Shader" { 
     Properties { 
        _MainTex ("Font Texture", 2D) = "white" {} 
        _Color ("Text Color", Color) = (1,1,1,1) 
     } 
     
     SubShader { 
        Tags { "Queue"="Transparent" "IgnoreProjector"="True" "RenderType"="Transparent" } 
        Lighting Off Cull Off ZWrite Off Fog { Mode Off } 
        Blend SrcAlpha OneMinusSrcAlpha 
        Pass { 
           Color [_Color] 
           SetTexture [_MainTex] { 
              combine primary, texture * primary 
           } 
        } 
     } 
 }

This one won't use the color set with TextMesh though.

Worked perfectly for me. As you said, the shader "disables" the color of Text$$anonymous$$esh, but you can set the color with the Shader ins$$anonymous$$d of the Text$$anonymous$$esh, so it's pretty much the same result. I attached a pic for future readers. alt text

@Eldoir Is it possible to do this for GUI elements such as Buttons as well? Fleshed out detailed question post link here. Unsure how this solution translates to Buttons as they allow for a variety of color options based on how they are interacted with (i.e.: Normal, Highlighted, Pressed, Disabled)

But where is the font texture?

I just got this working in my most recent project. That link someone else posted has instructions how to use it and you can set the colour too! (Link: http://wiki.unity3d.com/index.php?title=3DText)

Code

 Shader "GUI/3D Text Shader" { 
     Properties {
         _MainTex ("Font Texture", 2D) = "white" {}
         _Color ("Text Color", Color) = (1,1,1,1)
     }
  
     SubShader {
         Tags { "Queue"="Transparent" "IgnoreProjector"="True" "RenderType"="Transparent" }
         Lighting Off Cull Off ZWrite Off Fog { Mode Off }
         Blend SrcAlpha OneMinusSrcAlpha
         Pass {
             Color [_Color]
             SetTexture [_MainTex] {
                 combine primary, texture * primary
             }
         }
     }
 }

This is very old and may not be relevant any more, but in case someone still has this issue I just found out a super-easy solution to this problem: just set everything else's material's Rendering Mode to "transparent". In that way the right order of drawing is preserved.

You are a godsend. That worked perfectly.

Wouldn't that remove all those materials' support for deferred rendering though?

Uhm, this is a very bad idea. Rendering trasparent things is much more performance intensive, among other things that it will mess up

I don't know, but I haven't checked in a year, so maybe somebody has done it somewhere. $$anonymous$$eep looking. Good luck! And don't forget to post it here once you found a way, it may help someone.
