Am still not too familiar with the “mantra surface” shader and getting some errors when rendering. Hoping someone might be able to point me in the right direction.

When I assign a default mantra surface shader to geometry it renders (PBR or MP) with no errors.

Once I begin editing parameters in the tabs I start getting render error messages. Here's a sample…

mantra: VEX warning: Unknown parameter: ‘vm_truedisplace’ Undefined symbol
mantra: VEX warning: Unknown parameter: ‘0’ Undefined symbol

The more parameters I edit the more error messages I get… ‘noiseAmp’, ‘baseColor’, ‘refl_objs’, ‘refl_sep’, etc, etc.

Anyone else see this? Could this be an install or PATH issue?

Thanks


Edit: Received a reply from SESI support regarding this…

We've heard this complaint from other clients, I am adding you to bug# 43616
It seems somewhat related to using displacement shaders and surface shaders in the same network (as the mantra surface does).
In any case, the warnings are harmless…
