Hi Artur, do any of your models incorporate any analytic/CSG parts? I think you may need to convert any of this type of geometry to a mesh/surface type before exporting. This is because you can't directly map an analytic geometry object to a mesh/surface geometry object without reparameterizing it. For example, an analytic 'disk' object only needs one parameter - its radius - but a nurbs/sds disk object would also need to know in to how many segments the the circle must be divided, thus requiring an additional parameter. I used the export to .OBJ format feature quite a lot when I was making aircraft models for the flightgear flight sim and although there were some minor 'quirks' when using the Linux vers of RS3D I was able to get some very complex models exported Ok. Iirc, the hierarchy wasn't preserved but the individual models parts were, so I could still animate the individual sub-objects after recreating the hierarchy after export. However, being mindful of the limitations of surface geometry formats I only ever tried to export SDS objects to .OBJ format because there is a direct mapping between the the two. I also found it a good idea to look at my SDS models in the 'flat/polygonal' form before exporting, to check that any non-tri polys looked Ok - difficult to explain but easy to see - they can appear to 'curve' in the wrong direction - manually converting them to tris before export is the best way around this.
