I am am working on a project which involves my importing levels from a very old game using unreal editor 1 into UDK, and makingthem look nice :P.

Basically I use the .t3d import, and I export as a static mesh, with the intent of editing it in blender (or maybe maya, which I havnt tried yet), and re-importing it.

however many vertices of this mesh appear to be disconnected, and upon attempting to use the remesh tool, the model entirely disappears.

Is there a correct workflow for this? If anyone could help me with this I would be VERY grateful.

Thanks for your time!
