Hi all,

This is driving me crazy, I'm hoping that it's something silly that I've missed.

No matter what I set the "At Distance" value to (very small to very large)in the Principled Shader, I can't get the color to show up in the transparent geo.



I have a polygonal sphere, radius of 1, Transmission Color 1,0,0, and like I said, I've tried very small(.0001)and very large (1000) values in the "At Distance" parm, no change. I get the red in the caustics though, which is baffling to me.



Renderer is vanilla mantra, PBR.

What am I missing?

Hi. There's a toggle for "Enable Absorption and Nested Dielectrics" under Rendering->Shading tab in mantra ROP which needs to be enabled for transmission colour to work under PBR.

That was it, thank you
