Imported object as Physics SphereImpostor

Questions

Hello, when I import my own 3D sphere object and try to apply Physics SphereImpostor, the simulation does not work. But when I use balls created directly in Babylon.js, as in the examples on the playground - it works. Where can the problem be?

Adding @Cedric our Ammo king.

Not sure why exactly that wouldn’t work. Do you have a playground you can point us to to help troubleshoot?

You could also try the mesh imposter and see if that works?

Hi @Johny_Mickey

It looks like Ammojs crashes when building the acceleration structure for a triangle mesh. Are you sure you set the impostor to be a sphere? Also, how many triangles do you have in your sphere?

Hi @Johny_Mickey , I have the same problem. It tried capsule impostor for it and it works like sphere. Way around until the issue is resolved.
