Hey thanks guys.
Yeah Kraellin I left the grey lighter deliberately. Many of the tires or rather tread textures
I have seen for 3d are often too dark. Although tires and tread rubber are pretty black when
they are brand new, by the time they are on the road they have a fine layer of dust which combined with the way light hits rubber they usually appear quite a bit lighter.
So I figured I would err on the side of caution, which allows one to see the patterns better in choosing which one to use. Plus you can always darken them to taste. Much harder to lighten
them correctly.
at least 90 percent of all sensation is texture, even beyond the visual, with elements of noise, tone, gradients, interval and degree.
