ok, perhaps someone can help me do it on my own?

I downloaded this free model: https://gunpoint-3d.com/model-PBoat.html

and converted it from .3ds to .obj format using Quick3D, but once it is imported, the mesh can't be ungrouped at all, which makes it useless.

Is there a way around this?

Is there a better freeware/shareware model out there?
