Can I use models from other sims (eg Train Sim) with Rail3D?
Not directly, but (from #100 onwards) it is possible to convert MSTS models for Rail3D use. A conversion utility has been made to do this. The Rail 3 D development team entirely respects the right of msts authors to preserve copyright in their work and will not condone conversion of msts models without the original authors permission. For this reason, we do not publish the conversion tool, but msts model authors who are interested in converting their models are invited to contact the author mark@rail3d.
