the UTPT and WOTGreal can export meshes as .3d and .3ds formats but both of them deform 99% of the meshes in a .3d file. I've noticed that one of the vertexes in the model is moved to where the pivot is or was stretching the poly in a very ugly way making it impossible to use or fix the model. As for the .3ds files exported by them, I have not been able to get an actual import by the 3 programs I tried importing it to for some reason, its as if the file was corrupted somehow and cannot be read by the programs that support .3ds format... like Milkshape, Gmax, 3ds2unr.exe. So, my guess is that it is impossible as we know it since we havent seen any customization of UT's meshes.
I saw a zombie mod in UT2k4 that uses the UT99 player models and they all looked like they had the same animations used in UT and with no deformations either. Maybe those models do come out right but as far as the UT weapon meshes, I pretty much doubt it because we would have seen them used as a weapon mod for UT2k4 long time ago.
Also, I have tried all those export commands using DOS and none of them worked for me.
So, If you ever find a way to export the UT weapon meshes correctly, I'll be waiting for a shared download of the .3d files if possible.
oh, and a question to all... Is it possible to import Lightmapped meshes using a .3d file into UT99?
I also tried importing with psk/psa format to see if lightmap stayed in the mesh but it didnt.
