Hi there,
I just had a shot where I had a metallic object inside an organic Tube (SSS mat) with some vraydisplacement on it and render times gradually went through the roof:
Starting at an easy 10 Minutes per frame up to 3-4 hours per frame.
Once I turned of Vraydisplacement, render times were back to normal.
So apart from rendering in layers (rendering the metallic object with a dummy-non-reflective material and Vraydisplacement in the surrounding object durned on and then rendering another pass with the metallic material but vray displacement turned off), which I just did, is there anything I could do to avoid this from happening?
I watched some render nodes and I noticed that the memory got filled up pretty quickly and from there on render times went downhill.
I figured that due to the reflections a huge amount more of the environment han what´s visible in the frame needed to be calculated, that´s why the Vraydisplacement slowed the rendering down that much.
Am I on the right track?
