How to debug a shader?
Is there a way to debug a CGPROGRAM shader by setting breakpoints and seeing variables in a watch window? I couldn't get it to work (the red breakpoint symbol turns to a hollow ring - I'm assuming that means it's disabled).
There doesn't seem to be any info in the docs regarding the debugging of shader code.
Any help would be appreciated. I'm using Unity Pro if that makes any difference.
You can now debug shaders in Visual Studio. See this guide: http://forum.unity3d.com/threads/debugging-shaders-in-visual-studio.322186/
there's no way to debug shader using unity3d
shader is a special program that executes by GPU and can't be interacted.
you shoud use some third-party solution that emulates shader and try to run compiled shader there.
in unity the one easy way to debug what happened is to output values you want to check as color for geometry.
for example, simple row
return frac(IN.texcoord);
instead of return color can return a UV mapping info in color placed on geometry.
