Tips for improving performance on scene with >500 dynamic objects

Post by Justus » 13 Jun 2017, 20:52

Hi,

Do you have any tips to improve performance (time) in this scene: https://www.dropbox.com/s/v19822y3ce4zu ... e.ttt?dl=0

It is a very simple scene: a respondable plane with 500 cuboids on top. I've tried the most basic options: threaded rendering, changing the physics engine (+setting it to fast/long timesteps). Maybe there are more options to improve performance that I've overlooked.
All tips are very welcome!

Thanks,
Justus

PS: I've noticed that the Newton engine is extremely fast compared to the others in this scene, but physics don't work at all.

Hello Justus,

it is slow because the auto-sleep function for objects has been disabled in the physics engines to avoid different types of problems. At the same time, V-REP is not really designed for that type of simulations.
But looking at the Newton engine: it does not work because the mass of your objects is way too small. Try increasing the mass, then Newton will also work.

Cheers
