Disable body-body collision

[KingSnail]

Is it possible to disable bodies checking if they are colliding with other bodies and only check if they are colliding with the terrain.
This would drasticly reduce the strain on my server I think.
The bodies I am talking about are character controllers here, and I dont necessarily want player collision in my online game

you can by returning 0 in the
int (*NewtonOnAABBOverlap) (const NewtonMaterial* material, const NewtonBody* body0, const NewtonBody* body1, int threadIndex);

Hmm I did what you said and the collision is disabled for the body but not the head/feet?
I can walk through other players but I can still jump on their head? weird
Maybe I need to disable some kind of joint collisions on the character controller?
