Hi,
I make a box, instance it 200 times.
I select one box, isolate selection, then de-isolate selection.
- No material : <0.5s
- Diffuse material : 2s
- Mix Material : 20s !!!!!!
"octane isolate" works fine, but in octane viewer.
In max viewport it is very very (very) problematic...
I don't know in previous max or octane versions. My specs : 3dsmax 2022.2 and Octane 2020.2.5-11.12
