hello in my demo ChamaSlot i use many clone

i add tree or reed generator on terrain
(tree have physical box attached)
(reed have only 2 color material)

when i clone many of them fps slow down

any solution ?

Spread your cloning over several frames instead of doing them all in a tight loop, if you want to keep the framerate from slowing down.
Not sure how many you can do at once, you’ll have to try and tune.

thanks, your right i update reed with timer event
next step optimise the PoissonDisk population
