Hi,

I'm working on a leaf shader inside Houdini 16 and I came across strange problem.
I set up a dual shading model for PBR Diffue using ‘isfrontface’ condition, so for the front face I'm using Diffue and for back face Translucency and I get the result I wanted. But then when I plug in PBR Reflection after that, render gets stuck at 0.0% and nothing happens. Rendering without isfrontface condition with PBR Reflection layer works fine for both diffuse and translucency, but as soon as I add this condition Mantra is not respoding.

Any ideas why this is happening?

Attached shader network.

Thanks a lot,
Wojciech

I used the condition to mix between two BSDFs rather than two Diffuse Models and that seems to work fine!
