These do contain gamma compensation, though, and they contain colors that are supposed to be factors which will change when render GC is enabled. Unlike my more recent materials where I actually use gamma "correction", this is not so easy to change to remove the in-built compensations.

Remember the example of the Daz skin shaders - they do not contain gamma "correction", but the do contain "compensation" and they are unusable with render GC unless they are significantly re-parameterized. The same goes with this shader.

Basically this shader was designed around a non-linear color space and only works right with relatively narrow lighting conditions.

I'll take a look at updating this.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
