Ability to disable collision between specific components

The old physx (2.8.x) has this feature in which you can disable collision or notification within group. Eg disable collision between custom trigger with all other objects and this can be done as long as you have the object physics handle (in 2.8.x it was NxActor, it is probably the same thing too in 3.x).

You will also need to link to physx library directly.

All in all, it is most probably doable (havent tried it myself) without modding the engine source.

Thanks for the tip.

I had a bit of a dig around, but unfortunately can’t think of a way to set up custom collision filtering for the physx scene (either by filter shader or filter callback) as the PxSceneDesc is only used in FPhysScene::InitPhysScene and doesn’t seem to be accessible from anywhere else.
Not sure if that’s what you’re thinking of, but looks like you would probably have to mod the engine and change the filter shader.
