problem with export groups and UVs in Obj format

[Malo]

good evening,

When I export in Obj format a model with groups, the groups are well exported in the Obj file.
On the other hand, if I apply a UV to the model, the groups disappear in the exported Obj file.
Are there some things specific to do to export UVs and groups in the same Obj file?

Thank you in advance for your responses.

Try using the .3DS export instead and see if that contains your info. For some reason, the .obj exporter doesn't always deliver groups and things like that. But I think the .3DS exporter does.

Great, thank you Detbear!

Sadly another problem comme with 3DS export : the UV is bad

There is a way by directX export, groups and Uv are good.

Ouch. That 3ds UV looks pretty messed up. I wish that we could get both of those exports to deliver those maps correctly. I hope you can get the desired result. Sorry I'm not much help there. I have experienced troubles getting the .obj export to contain maps when I open them in other Apps

Yes I can get the desired result by "the AMXtex DirectX Model (*.X)..." plugin, thanks.

Which program are you taking the AMXtex export to?

I use this AM's plugin : https://www.patchwork3d.de/am-directx-exporter-73-de

And I use this blender's addon to import the .x format in Blender : https://github.com/littleneo/directX_blender/wiki
