Ah, thanks for mentioning the cars, I didn't know that. But personally I haven't been doing cars.
I finished Korea for rFactor a few weeks ago, it was good enough for our league race, but was still lacking tyre barriers.
Korea is virtually the only track playable at the moment, because luckily it has Armco barriers all around the track.
But if you look at virtually any other track in 2.10, you will see overhead gantry's out of scale, and missing walls.
Interlagos for example, I was all excited and going at it pulling an all-nighter - then I realised Sector 3 has like no outer walls.
Also the pit exit, basically anything animated or related to tyre walls isn't imported properly.
Interlagos and Hungaroring are sitting on my hard drive doing nothing, because they have gaping holes in the side of the track
I don't have the skill in 3DSMax to re-design the walls, so I would rather wait and see if you can fix the problem.
Thanks again for probably the most important software EVER made for games
