Title: HEAVILY increased "preparing objects" latest ForestPack, Max 2021.1 - VRay Next

Hi Guys

We're on Next, but have noticed an increase in scene preperation "preparing objects" on heavy forestpack objects with plenty grass, trees, mulch etc. On a typical small test scene you dont notice this, but on all heavy productions scenes you do.

For example we have a current project where it does a frame in 18 minutes, however only 8 minutes is actual rendering time! About 2 minutes is denoising and exporting render elements, so the scene takes almost longer to prepare than the actual render! It seems to get stuck on preparing forest objects.

It may be related to 2021.1, I can't remember this happening on 2019......

Should You send us the scene we could investigate Forest Pack influence in that and compare it with previous FP versions.

I think I'm experiencing something like this too.

I have a large site and I used the forest pro grass preset on it... Rendered fine, no problems. At some point, after many changes in the scene but none of them to do with the grass... The grass starts doing this thing where it is stuck on "updating instances" for aaaaaaages (like 5-10 minutes). Eventually it renders.

It's using a preset, so no big deal, I delete the forest pro object from the scene and re-create the grass as before. It now renders absolutely fine.

Fast forward a day... It is now doing this with my trees (not a preset). So it looks like I'm going to have to delete the trees and replace them.

Replied via email.
Explanation- ForestPack for the grass had edge mode enabled. As surface was quite big and grass density high- it took some time to process it.
