I don't know whether I should make one thread for each question: if so, please tell me. I just think that the answers are probably so simple (even if I don't know what they are!) that they don't deserve a thread each. 1 - Ever since I downloaded v.0.6 I haven't been able to export the tracks to RFactor because I get a SKY error. It says it can't find the SKY.MAS file (I think it's .MAS, I'm not so sure now :confused2. 2 - I can't use SObjects or new objects such as lights for my pre-v.0.6 projects, but I can use them in new tracks. Any thoughts?
