Project: Paper2D

RE: Collision issue, I haven’t seen an issue like that, have you created an AnswerHub thread with more information?

Yeah, setting collision domain to 2D on any Paper2D asset type will use Box2D instead of PhysX, but note: is truly experimental, it does not get any testing from QA, it is only compiled for Windows, and is unlikely to be developed further for foreseeable future. I’d recommend instead using 3D domain plus planar constraints options for basically any game (you can either enable it on a per-component basis or globally for your entire project in Project Settings … Physics).

Cheers,
