Thanks for sharing the idea. It feels hacky to me too but maybe I’ll try it.

I was reading the topic

I’ve taken the bit and parts and ported them over one by one. If I remember correctly, very few, if any, changes are needed to make it work. In the castRay function of your raycaster, you simply put: rayCallback.m_collisionFilterMask = collisionFilterMask; rayCallback.m_collisionFilterGroup = collisionFilterGroup; Before you do the rayTest. So between setting the result callback and calling the rayTest function. Then it’s automatically handled. Then you just need a way of setting your mas…

and I was wondering if the friction is not working out of the box and some digging in the AmmoJS code (custom build?) is required?
@Raggar maybe you will know?
