It should be either free or at least affordable.
I've seen Wings3D so far, but no idea if this suits my needs and I have an old version of Truespace (3.2).
Any suggestions are welcome
Yeah DXF is importable by Unreal, the downside of it, it cannot contain textures. Those needs to be re-added in the editor afterwards, inlike t3d or (unr for that matter).I can't remember if the DXF to Unreal worked last time I tried it
also scaling the model is going to be 'fun'
