Cannot get custom collision (Hollow sphere) to import

[SgtFlexxx]

Hi all,

I’m not sure what I’m doing wrong according to the documentation, but I cannot get my custom collision to import.

I wanted to import a Hollow sphere collision. I broke up the sphere into a bunch of prisms and renamed them UBX_[meshname]_## but it won’t import the collision at all. I tried both GLTF and FBX format, but neither work. I’ve included images as well as the files themselves.

UBX prefix is for regular 3d rectangle shapes, you should try UCX.

That worked, but I’m a little confused as to why. All my hulls are made up of 6 sides which I thought was what UBX was intended for. Does rectangular mean like the corners have to be 90 degrees each?

Regardless, thank you!
