Author Topic: Slow performance when selecting forest Objects with active modify Panel  (Read 424 times)

in 3ds Max (2019) Selecting a Forest Object with the Modify panel open is extremely slow.
In some cases, it may take up to 30 seconds before the panel is loaded.

it's instant when selecting with any other tab open.

It seems to be a little bit quicker if you close all rollouts before deselecting.

Anyone else have this issue and a solution?

30s is unacceptable, of course.
how long does it take to select editable poly in modify tab?

What CPU do You have?
I have AMD 1gen thread ripper and that CPU is slower than my old intel PC when selecting any object in modify tab.
It takes up to 4 seconds at MAX to select ForestPack object when having multiple max versions running etc.
