Hi there,
I recently had some trouble with the Ss2 material. It happens rarely, but when it does its really annoying and I couldn´t find a way to get rid of it yet.
Due to rendertimes I always used "prepass based illumination" instead of "Raytraced", since it still renders 3-5 times faster.
On my last animation I got some nasty flickering/artefacts on one of the SSS2 materials though.
I usually get away with a prepass rate of -1, even for production, but since the objects were moving quite fast, I tried increasing it up to 1, but the problem still persisted.
I also tried switching to "object based illumination" map (I think that was only introduced in the nightlies, we are on version 3.004) with samples per unit set to 64 but I still got those flickering problems.
I don´t have the time right now to fix the issue, so i was wondering if you encounter that from time to time and have a solution.
Also I never quite understood what the prepass mode was for and if or how I should use it for animation.
There is no GI in the scene, but I know about the flickerfree approach with Irmap and since the prepass for sss is kind of a similar solution, I was wondering If it needs to be treated the same...
