Yes of course:) I will post it here in a moment, after I verify it is actually working:)
It is my impression that there is no keyframes, but a lot of exporters provide the
ability to automatically export each frame as a separate obj file.
I have found this link which explains a little better...
http://www.fileformat.info/format/wavefrontobj/Basically, it is a format which is unusually common. Even more so than 3ds, because it is described better.
It explains there is a ASCII and a BINARY version. According to the website, the ASCII one is free, and the BINARY one is more propriety, and hidden.
It supports UV Mapping, according to the website, and blender's exporter specs...
http://mediawiki.blender.org/index.php/Scripts/Manual/Export/wavefront_objIt explains that there isn't really any header information needed.
The spec explains that the information is stored on lines, with the first word
describing its purpose...
-geometric vertices (v)
-texture vertices (vt)
-vertex normals (vn)
Now the file below, is a model I made. I exported it in blender, and it DOES have "vt" lines, which are texture coords, so it seems to be working.
I have noticed that the exporter offers to save the Material data in a separate file, however, this data can be embedded into the file itself, or, probably, not used at all, because it only points to the filename of the texture, which can be done in jpct anyway.
