That’s a precomputed shader. Unity no longer supports using precomputed shaders as shader assets, and has not for several years.

At the same time I’m not really sure what the purpose of this shader is. It is literally invisible and will write nothing. Ignoring what’s in the vertex and fragment shaders, which appears to do the basic transform of the vertex positions into clip space and output the vertex color, it’s using ColorMask 0 and ZWrite Off.

ColorMask 0 means it won’t output to any color channels, only to the depth & stencil. ZWrite Off means it won’t write to the depth buffer. And the shader has no Stencil settings so it won’t write to the stencil buffer either.

So, basically it’s a shader that wastes GPU cycles to do absolutely nothing.
