Hi there. For many years I've had an OpenOffice Draw file on my PC with a concept of a track I'd one day like to drive in a sim. It includes three crossovers a la Suzuka, and a couple of alternative layouts. I have no time to learn how to use 3DMax or anything but I wondered whether BTB - which looks fairly easy to pick up and achieve something basic in - might be worth my effort. I mean, assuming I could realise a 3D model of the basic layout and topology, would that be usable by someone with experience in full track building to make a working circuit in Grand Prix Legends and/or rFactor2? Usable in the sense of being something they can take, edit, tidy up and flesh out, rather than usable in the sense of merely being able to visualise what I intend but having to start from scratch in, for example, 3DMax? Thanks.
