I’m just learning how a shader works. So, I just copied from the built-in sprite effect file to mine. Now, back to the issue, I think, only “cc_matWorld” is used from #include <builtin/uniforms/cc-local> If I commented both of these lines, there were no error. But, everything stopped working as intended.

Hello, so my issue is such, I have made a shader that causes a UV distortion in the fragment shader, to simulate “flame-like” effects at the edges. There are two variants of these shaders, one where the distortion is dependent on cc_time[0] i.e the time elapsed in seconds when a game is running. 1.0 - newUV.x), min(newUV.y,
