Truth about Animation Prepass

[re:FORM]

Wow, if that's the case, that's good news. I'll give it a go and report back.

It makes me think it might be a good development to add an "incremental add to prepass" option in the IR calculation for scenes that have a fixed animation, but multiple cameras. After the first camera prepass has been calculated, subsequent camera prepasses would preload any existing IR-map (for the current frame) and then only have to calculate the missing samples. The only downside I can think of is excessively large prepass files....

I'm not sure how useful this would be to the wider vray community, but for my current job this would be a great timesaver.

For short film projects this would come in really handy - from what I gather a lot of people that use GI based rendering just have each scene with all the animation in and then a number of different cameras in it to edit the shots together from.
I know we've done a few interior animations for a buildup that had 2 or 3 cameras that needed rendering too.
