Default missing UV map from 3DS export

After exporting (any) model as 3DS, the UVs are lost.

also, an .OBJ exported from ac3d shows up blank in Photoshop CS4

I'm trying to get any model exported from AC3D to PS CS4 extendend.

I understand it will be hard to fix the .obj problem, but it's clear that the 3DS export doesn't work, because when I re-open the exported .3ds back in ac3d, the UV map is missing as well.

Do you mean the texture itself, or the UV coordinates?

I cant see any issues with the UV coordinates - the texture coordinates appear to be intact on objects exported/imported - so I'll assume it's the textures.

If it's the texture itself you're looking for, I'm guessing you're storing your 3ds file in a separate folder from where you're storing your texture. The 3DS format only allows an 8 character filename with a 3 character extension for a texture name. Unfortunately, this is a limitation of the file format, and I believe there's nothing AC3D can do about it.

This means if the texture file isn't in the same directory as the 3ds file, it will not import because it doesn't have the full path to the texture file, only the 8.3 filename.

The only workaround I know is to place the texture file in the same directory as the 3ds model. Other apps have similar problems loading 3DS files, and the solution is usually to keep the texture and model files together.

Was your original object textured when you exported it as 3DS?

No, for this example I just opened falcon.ac (from the sample models included with ac3d) and exported it to 3DS without changing anything. As you can see the UV map is there in the sample file, but no longer there after the export.

If you texture it, there will be texture coordinates in the exported 3DS file.
