Hi! I guess some of those tracks, were already converted. Well, I guess these tracks that I have (Agua Azul, Tsarskoye Selo and Cape Town) are already conversions from GP2, but it is always nice to have updates and improvements. Like some jam files and Magic Data. Go for it!
For example, at Agua Azul, in the pit lane, i doesn't have any garages, and regarding cameras they only are set right in half of the track.
Cape Town would be nice if the turn 3 & 4 section could be changed to just one corner, like it is in the real track proposal. [
etracksonline.co.uk] It would become a great point for passing.
Talking about Portuguese tracks, more precisely Porto (2005/2007), if one day you decide to make it, I have photos of at least 3 quarters of the track if it serves any help on, more or less, guiding you on how large is the track and other stuff, like scenery...
Can I suggest too, the modern version of the Vila Real track, and the Ota Airfield circuit that was used while Estoril was being remodeled to the current layout.
Well, whatever you do, I wish you the best of luck.
Thanks for keep making this game even better than it already is
Cheers
