glass shader with objects inside

Hi!

Yes the Faux caustic seems to help but in reality caustic is a completely different phenomena and it will cause the entire refraction to be exposed (Capture 3). But I found the actual solution under the Mantra Rop in shading setting allowable paths to ALL PATHS!!! I don't understand why on earth this is not so by default! This do raytrace the glass properly.

 

Updated to latest build and now I have problems with the refraction again even after applying all paths will fill for a bug report.

I think SideFX is about to rework their glass shader.

Yes, it seems there are a lot of redundancies and errors going on there, probably because of the change to PBR rendering...but my story i think is quite particular as...somewhere between build 607 and 673 they change the way faux Caustic works and the problem with over exposure doesn't exist anymore. but the ALL path solution suddenly doesn't work!

The result is the same now and finally I have proper behavior on glass.
I was about to start to build a proper library of materials in mantra....this first step did not make it easy :/

To be honest I am suprised this didn't come up early....
