Generate custom collisions for a high poly static mesh using a low poly static mesh

[TheFlyingEpergne]

Hey

I’ve got a “high poly” static mesh and i’ve created a low poly mesh that i want to use as its collision.

I’ve giving both meshes the same name in blender but giving the collision mesh the “UCX_” prefix but unreal doesn’t register it as the collision.

Is there a way to do this manually from within the engine’s static mesh editor (ideally without having two static mesh actors inside an actor bp)?

Thanks!

Hi TheFlyingEpergne,

Try setting the collision mesh here:

I think that’s done it!

In case anyone else stumbles across this, I also had to go into the collision static mesh and set that to use Complex collision too, then it would work with the high poly mesh
