MR Flickering Glass

[otuama]

Hi all.

I’m producing some 360 animations of buildings.

I’ve been doing it 2 ways:

1: The camera simply rotates around the building.
2: The camera rotates around the building but also the sun rotates too. This gives a nice shadowing effect.

With the 1st option I don’t get flicking glass because I can create a final gather map. However, the 1st option is boring!

Here’s the 2nd option. It’s much better visually but the glass flickers. We’re rendering with a strange res for these so it’s not HD.

I’ve been told that, because the light is animated, going the final gather export route won’t work as it only works if only the camera is animated.

Can anyone think of a way to get rid of the flickering glass in a situation like this without bumping up the render time a lot?

Thanks

Not a MR guru but it looks like (this may be obvious) you’re seeing the reflection of areas not directly in camera, and therefore not getting nearly enough fg samples. But MR should be giving it as many samples as it needs, if it’s being traced properly - have you turned down any reflection settings? Maybe add a diffuse bounce, a reflection bounce, or even a cg light?
