Slippery/bumpy surfaces

[joevenzon]

For bumpiness, here's what I did in the listedit tool for road atlanta:

Code:

set 0 * 6 2.0
set 0 * 7 0.03
set 1 road* 7 0

The first two lines set all objects to have grass-y bump numbers (from vamos' concept of grass): 2.0 m bump wavelength, 0.03 m bump height. The third line sets all road objects to have 0 m bump height (no bumps).
