Hi again folks, It seems I keep coming here and pestering people for help with this circuit project; sooo many things keep going wrong and I'm losing tons of hair! X-( Ok, to the point: I've made a pit garage prop in AC3D and placed a couple of very basic texture files on it (one plain red, the other plain grey) just to check that everything fits nicely in Rfactor. My circuit begins to load and then crashes, every single time! To begin with, I was using really high-res textures and I thought this was what was causing the crash, so I switched to tiny files to check this and, while it's still crashing, it appears to have changed something, because the progress bar doesn't reach nearly as far as it did with the large textures. If anyone can shed a little light on this one, I'd be very grateful! Could it be the meshes? They're not overly detailed yet, but I'm hoping to make them so if their basic structures fit well with the rest of the venue's style. Thankyou for reading! Glen.
