I just noticed something when trying to export in different formats in BTB: When you export for rFactor, the program uses a different default skybox/horizon than when exporting to GTR2. So the track looks different (in my case, not as it should be) in GTR2 and probably other sims. Notsogood for consistency... (This was just a test, but I would prefer to release for several sims beside rF.) Is it possible to convert sky.mas files to other sims? I tried converting the rF skyboxi gmt files to gtr2 format, but that doesn't seem to do the trick.
