When I last read this thread there was really nothing serious going on apart of skinpack and 1.6T engine declaration. I started WTCC 2011 mod on my own and spend lots of hours on it past last two weeks. I PMed zolib about permissions and found out that the thing got rolling. If he doesn't allow me to use his skins I'll most probably abandon work cause doing a mod for your own use is rather pointless. Moreover I would need to triple myself to even think about making things faster than such a team. I was going to write a big post on WTCC 2011 thread on NGR today but well, things got screwed.
I'll allow myself to show you what I have done so far. Maybe this would be of some use to you. Apart of most skins this is one-man-project, so please be gentle. Please keep in mind I haven't been replied about some permissions yet. The BMW skins I have made are: Urs Sonderegger, Marchy Lee (conversion from zolibphc), Fabio Fabiani, Mehdi Bennani and Javier Villa.
