I use either Fragmotion or Blender to texture my
models, and then bring it in.
Wings exports to .3DS and .X and .FBX so one of them
would work (haven't tried it recently)...

Wings doesn't animate, but it is a REALLY good low-poly tool....
Wings texturing isn't fun.... but exists...
(you can even model only with wings, and texture / animate elsewhere,
(Blender - free , Fragmotion $15, characterfx - free,
and I think there are other free animators, but I don't know much about --
K-3D, Art of Illusion)
