Are there "ideal" settings to use to reduce flicker in animations with refractive GI turned on? I really like how the refractive GI looks in stills, but for animations the flicker I'm getting makes it unusable. The transparent material is (non-glossy) glass. I've tried cranking my irmap accuracy settings but nothing seems to remove the flicker.
Here are the highest settings I've used so far:
Min/max -3/1
Subdivs 50
Interp 150
Interp frames 2
Color thresh .2, normal .1, dist .5
My background is mental ray so my usual approach with final gather was always to use a relatively low accuracy with high interpolation to avoid flicker.
Even with a prepass there is still quite a lot of flicker happening in the GI caustics. I could always use the "affect shadows" option but it doesn't look nearly as good; I actually don't seem to get any shadows from the glass at all in this case. Are there specific settings I should be changing in order to clean this up? Or are GI caustics just not an option for animation right now? Are there alternatives?
