Am I doing something wrong here?

You seem to be mixing V1 and V2 physics:

There is no information on that concerning the v1 v2 that you referenced on the link that you sent that I can see.

And I also see direct code examples doing the exact same same thing.

Can you show me a typescript playground with it working then?

I’ve also tried different inits of the plugin none of which have worked.

If you follow directly the documentation in a typescript playground it seems to not work.

I’m probably doing something wrong though.

You are trying to create an impostor/V1, but Havok/V2 uses aggregates instead.

Thank you! This is the info I needed.
