Title: CoronaSkinMtl and RaySwitchMtl BUG!
Post by: Azamat Gasimov on 2017-10-06, 19:26:34

Hello! CoronaSkinMtl material and CoronaRaySwitchMtl don't work together! SkinMtl becomes black after loading into the any RaySwitchMtl slot!

Hi,
I quickly tried to reproduce it, but failed, can you post a simple scene of your setup?

Any, even the most simple scene produces the same result.

I use last build - rc7.

Same happens if plug Corona material in SSS mode. Turning SSS amount down to 0 in both materials, gradually makes them to render normally in conjunction with rayswitcher.
Scene attached.

Off-topic: What's up with the shadow terminator in the pic above? Shouldn't this look way better now or did you disable it?

I don't know, probably SSS doesn't play well with terminator. As soon as SSS is turned off in both CoronaMtl and CoronaSkinMtl, terminator is smooth again.
