UV's arent exporting in the OBJ format.

Have you checked Edit > Options > File Format Options?

Can you detail the problem?

ya on the obj File Format Options, i got Vertex Normals and Regroup polygons by Meshes Checked off, and a export scale of 1.

when i import the exported obj with maya, or blender, the UV's are just completely blank, even if i import the exported obj back into Voidworld.

if i export as the Dae Format i get no issues, and the UV's come across fine.

this isn't a huge deal for me since i don't normally UV in VW, but with shapes made using the slide spline tool, it can be helpful to use the UV's it generates as a starting point.

i ended up having to just delete the geometry i made with the slide+tube tool and remake it with a renderable curve in maya, since those kinda shapes are a huge pain to UV unless you got some auto UVs from the creation of the object.

In the uved_plane_vw.obj file, vt values are missing. Make sure Edit > Options > File Format Options > obj > Export Textures is checked.

that did the job, you might want to change the wording of that option, i thought that would just export out a texture if i had one applied to the mesh in voidworld, not stop it from exporting the UV information.

never would of connected the 2 since in maya, you can disable exporting of textures and materials, and the UV's still get exported.
