Hey all,

I'm trying to work on some procedural textures from COPs, but my path sourcing doesn't seem to be working.
I'm replicating others demonstrations (the example files do work for me) but something in my personal scene doesn't like it.

Should just be black on red noise, but I'm getting pink shader errors obviously.

Can anyone take a look and find my mistake?

Thanks,

I don't think so, but thanks for trying.

It looks like you don't have C plane in your outputs. “op:cop_path” is expecting C plane (at least I didn't find a way to reference arbitrary plane)

So just make sure that OUT_RED has C plane. You can just copy C.r to C in channelcopy, that way you'll have grayscale image
