"Scale": Used for im- and export. find out what your modeller needs (blender works fine with 10).

"Silent IM-/Export": Don't ask for filenames. Uses the same file name as last time (if a filename is known already).

"Create Masterbutton" does nothing at the moment.

"Export Groups": Will create groupnames (actor names) in the OBJ file. Blender can use this to create vertexgroups.

"Export UV info": Saves Material und UV-Textures if checked.

"Copy Imagefiles": Creates copies of the texturefiles in the path the exported object resides (so your modeller can find it).
