Trackside terrain, grass, overlapping

[Risto Kappet]

Hi

I projected a nice racing-kart track from google earth and it all works great, even has
all the height changes that the track has but whenever i try to add grass around the track, then
whenever i put more than around 10 of the size, grass starts going on to the track itself.
I would like to put atleast 40 for the value to add distant forest as in real life but if i put
such a big amount then almost all of the track will be covered with grass.

Or, any tutorial how to add the grass (and some hills next to the track) manually, would be great.
I see the option to drag it but nothing happens if i do.

Thanks

Your talking about terrain autogeneration? On tight turns you need to narrow terrain panel sizes and numbers. The autogeneration rarely works as is, best option is to use "Click&Drag" so you can use wider panels in the straights and modify the parameters for tight turns.
