Sorry to bump the thread with a semi-OT question, but is there a thread discussing the issues occuring when using Blend materials? As far as I've seen they work just fine here but I may have overlooked something?
Hi,
for the most part, they should work. But some features don't... you can not mix emitters (CoronaLightMTL), displacement doesn't work on blended material..., blended refractive materials sometimes produce odd results, and things like that...
But as long as everything works the way it should, you should not be concerned... there's nothing bad happening under the hood... Of course... blended materials will never be as fast as base ones... but that is to be expected with most renderers which are not build around layered shading system...
