Is it possible to enable gravity and collision separately for a mesh

[Takemura]

checkCollisions uses the native collision system of BabylonJS, so in case of physics engine set it to false.

In the physics engine you can set collisionFilterGroup and collisionFilterMask. A collision between A and B will happen if A.collisionFilterGroup & b.collisionFilterMask !== 0.

So for every “digit” of A and B the AND-operator is applied. By default group and mask is -1.

The example PG of @Cedric:

Babylon.js Playground

But I recommend to use new Havok physics engine:

Using Havok and the Havok Plugin | Babylon.js Documentation

How collision filters are set in Havok:

Is there a way to use collisionGroup/collisionMask in havok physics?

https://www.iforce2d.net/b2dtut/collision-filtering I need functions such as categoryBits and maskBits of box 2d, but I don’t think there is this specification in ‘PhysicsBody’ of Babylon js. Is there any way to do this?
