So this may be a relatively minor thing/nitpick but I wanted to check anyway, is the current state of livetrack shade final? First is a picture of heavy rubber in ams2, I tried to make a similar shot of PC2 below. The AMS2 one looks a bit odd, like it has a very clear start and finish and a really unnatural shape and the shade kinda looks like a tea stain rather than a heavily used track (and all tracks seem to have almost exactly the same shade and shape)
Agree, the definitive line where the rubber starts and finishes is bad, really needs a blend line and the colour could do with an adjustment.
