Hello,
Is it possible to replace the road from "road and tarmac " with my own road ?
Bastien..
Is it possible to create a road or paint the layout with the "painted shader" ?
FrankB should answer your first question, but I guess if you hit the warping seed (a power fractal probably), you get another road layout. Or if you move the simple shape shaders involved to another location.
The answer to your second question is negative, unless you want a road, which is not very straight or defined, and without the lines.
Hope this helps a bit.
You can change the position of the road and its orientation (rotation). The curves are procedural, so you can only reseed the fractal that produces the curves, or make the curves larger or smaller, but you cannot exactly determine or paint the path for the road.
Regards,
Frank
