The PG is already using instances, so it should be ok on the rendering side. However, there are still ~3500 meshes in the scene, so using thin instances may be a win in the end.

Very cool, Iāve recently done a physX port for playcanvas complete with mesh collisions and character controller etc. Have you tried using raycasts yet? Iām having major issues with them where I have a perfectly normal box rigidbody with scene_query flag set (and trigger) but it only ray casts on 4 of the sides of the box. Its really bafflingā¦ Whats even more strange is if i move close it and look at it head on it does then seem to ray cast against that faceā¦
@Adriaaaaan , 
sorry I canāt help you, Iām just playing with #fabmax port, no intention and no time for the moment to dig futher with PhysX.
I have encountered the same requirement recently, and I am confused about how Babylonjs introduces physx. Can you give me a demo github address? extremely gratefulļ¼
babylonjs didnāt introduce physx officially. we donāt have a plugin for it
