Look at the pavement, there are clear lines where it gets lighter and lighter as you travel up the road. I am using a just a simple vray material with a Smoke map in the diffuse and noise map in the bump. Where are these lines coming from? Thanx all
Does it have any displacement? What happens if you disable the bump map?
Best regards,

Nah…No displacement…But I thinkI figured it out…The number of iterations was set to 7 for some reason…When I changed it to 1, it went away, but got darker…SO I just lightened the bitmap a tad…Thanx…Oh…I cant login to the new site either… 
Is the smoke’s mapping set to “Object XYZ” if so different object will get different size smoke. Best to use world XYZ if your using it on multiple objects.
