when exporting (our own exporter using AutoDesk FBX SDK)
to a .FBX format, texture UV’s seems to be fine (checking in Maya), but
when exporting to .OBJ file, no texture UV’s are added to the file.
any special flags need to be raised or any special method have to be used in
order to see UV mapping of an OBJ file ?

Hi Carlos,
thanks for the quick reply. now the plot thickens…
when I export from our app to the fbx format - everything looks fine in maya - geometry has it’s UV map. When I try exporting to .Obj - no UV’s in maya. both processes use the same layers and scene objects, just the file extension is different. o.k, so I tried a workaround : i’m filling the KFbxScene with our data - vertices, UV’s, texture layers etc’, saving to .fbx, loading the .fbx file to the KFbxScene object with your “import” method and saving this scene with an .Obj extension - and this creates - miraculously - a correct .Obj file with all UV data in.
naturally, this workaround is not something i’d like to keep in my code, so, do you have any clue on the reason for this failure to save .Obj ? do you have a code that fills a simple geometry and exports it, so i can implant this code and build from there ?
thanks again,
Udi
