lighttracing disables reflections on disney

Post by lacilaci » Thu Aug 15, 2019 11:25 am

when using disney material and lighttracing material reflections gets disabled when using glossiness bellow 0.05

to best illustrate the problem I've put metallic slider on disney to max but the problem is present even without it

disney at glossiness 0.05

disney at glossiness on anything bellow 0.05

this is not happening on glossy2 and metal material which work the same even when using lighttracing

the problem is not present when lighttracing is disabled

I think that what you're observing, are light rays that don't get to the eye. And if IIRC, it's already mentioned couple of times.
Take notes & simply don't go under/over the threshold. ;)

Not sure what you mean, and also why the different behavior between disney and others...

Yes, it works now.

BTW, while we're dealing with Disney's reflections - where's its Fresnel/IOR setting?

It is part of additional features introduced at SIGGRAPH 2015, we have only SIGGRAPH 2012 features at the moment.
