Hi guys,
haven't had a lot of time lately, but last night I finished a next iteration of my procedural road.
Volker helped me to get me on track with cutting and elevating a road bed based on the terrain. Also the rock and grass textures are his.
Besides that, my road is now following a curved path, builds "bridges" over depressions and cuts nicely into hills.
Because this road isn't based on a simple shape shader or anything like that, the road is infinite around the planet, so no matter at what elevation you have the camera, the road won't suddenly end.
I still have to do some cracks and patches on the road procedurally, and make it rotateable. I guess the latter will require a lot of re-wiring the network.
So summarizing what's procedural in this scene:
1 - the terrain
2 - the road and road paint masks
3 - the rock and grass texures
4 - the tarmac and the paint
5 - the curving of the road
... in other words, absolutely everyhing except the vegetation
I love procedural.
Cheers,
Frank
