I’m working with a massive scene, and now I’m using a relatively reduced version to do some animation, (when I say reduced I mean 42 million polys on viewport + instances , 4240 objects, that is the super-reduced version)
Cycles viewport render is working well, now I noticed that when I enter in the viewport render for the first time it takes a while, like in the normal viewport, but when I change to a different frame it just updates part of that BVH, it does not re-create the whole thing, so it’s way faster.
Could this be enabled for final render? even as a testing thing, because if this works from frame to frame it could save us A TON of render hours, it could have some cons I can’t see, but so far even with these cons, if it works, it would help A LOT.
To compare times, in this exact case, starting the viewport render takes 1 minute 35 seconds, while changing frame takes 5 seconds.
