Hi!
I'm so sorry, I still haven't had a chance to follow up on this and send you a scene (moved countries last month, busy times!).
However, I DO have an update of sorts. Please watch the video here:
Basically, when I have some scatters, even when they are as simple as possible, in my scene(s) it still takes a very long time in C11 to hide/unhide when I have scatters.
If I disable the auto-update on the scatters this no longer is an issue. I know this sounds kinda obvious, but it's a new behavior that the hide/unhide is super slow and I believe it shouldn't be the case when I have very basic scatters...or even when no geometry is changed (ie; the scatters don't need to recalculate). All I'm changing is the hide/unhide and for some reason this takes a very long time (much longer than pre-Corona 11)
Any thoughts?
Edit: I should reiterate: I believe this to be a problem with the latest version of Chaos Scatter, not Corona!
