I have done some tests with textures and find out some problem. If i wanna create with Add Walls tool the ditch and lately create the surronding terrain texture. Terrain go over to "ditch", is that possible to create terrain what is linked to "ditch" not the road? BTB is great program to create rFactor tracks, but Richard Burns Rally track creation need to more detailed than rFactor because ditches etc.. That is great if that terrain creation would be possible to start lately. Because terrain material editing is more time taking than editing the Walls. Surely that terrain "starting" point is possible to write into program programming code but how time taking it would be, long process. That terrain/wall thing came into my mind when i trying to work some detailed track surrounding.
