I'm working on my first unit and getting it UV mapped in Upspring. It's a self-propelled gun with two parts as .obj's - the hull and the gun.
Link to it's 60-poly glory:
Following one of the tutorials, I made the two parts separately then exported them as .obj. Then I imported them into Upspring and then re-exported for UV mapping. I generated a UV map in Wings although it wouldn't let me make a very good one (all the faces were separate and it wouldn't let me unfold them nicely). But I still had a .bmp.
I go back into Upspring and generate both textures from bitmaps (no glow, no team color yet, 1 bit of reflectivity for the hell of it). Texture 1 displays as a dull, light gray. It's not the team color being screwed up, because I regenerate the texture and invert the team color .bmp, and then I see the whole thing in team color. I also flipped the UV map, so I don't think it's that either.
I'm fairly certain the UV coordinates are getting lost, but I really don't know what to do.
Well, I think I was saving the UV coordinates because now I can get most of the texture to work.
However, the gun, which is a separate .obj file imported into Upspring, isn't being textured properly because it's not getting UV mapped in wings.
I have three .obj files - the gun, the hull, and the two of them together as a single object. I UV map the .obj file that has both combined and it looks correct in Wings. However, when I import the UV coordinates from it into Upspring, only the hull has UV coordinates.
I'm still not sure what I'm doing wrong, though I'm a lot close. Thanks!

wait a sec does wings allow for pieces? because this whole time ive been pulling my hair out trying to find a uv mapper that wont mess with the geometry every time i export for uv map do all that hard work import and upspring doesnt even recognize it! grrrrrr

...and break your normals while you are at it. Unless you redo them in Upspring which is only possible when you really export all hard-edged and round objects as single objects and merge them together after smoothing them, otherwise the auto-smoother is useless.
Anyway, ... File -> Export Selected -> highlight Wavefront OBJ => hit Ctrl+Insert, <key to assign to>. Now group your pieces together, select one group and hit the newly defined key to export your current selection as OBJ.
I don't really understand what you mean with losing UVs though.
I always redo smoothing in UpSpring. If you adjust the angles correctly, your results are just fine, frankly. I've only had one situation where I felt like importing like that wasn't a complete waste of time. That said, by all means, do whatever works for you. I just think that's the fastest way to go about it.
