Question by Toxast · May 05, 2014 at 08:09 AM · shadercullingkeywords

Shaders: Turn culling on/off by keyword

It seems that #pragma multi_compile together with keywords can be used only in CGPROGRAM ENDCG block.

What i need is just to turn on/off culling in runtime. like that:

           SubShader { 
                 Tags { "RenderType"="Opaque" }
                 LOD 100
     #if defined (CULLING_OFF)
                 Cull Off
     #endif
         
                 CGPROGRAM
                //sufrace shader ...
 


but i get a syntax error there.

I'd like to know what the ideal solution to this is as well so we don't need to have different shaders entirely for different cull modes.
