Quadraxas: Maybe no palette.pcx file exists, or it can not be accessed due to some attribute setting? When you assign a palette under Map Properties, make sure that it can be found in the work folder or in the WED folder. By default, Gamestudio contains a palette.pcx in its folder.

Locus: 3DS and OBJ models should work, I tested them here successfully. I haven't tested DAE import, therefore it doesn't appear in the feature list. But it should work also, at least according to Discreet who wrote the filter.

Does the .OBJ file import in MED? If so, can you send it to Support?
