Re: how to restrict terrain generation to the inside of the track

Cool, you seem to be very busy with TORCS, great:-)

I cannot load the image for some reason, but lest have a look...
Ok, I cannot see an option which helps you without using a 3d-modeler 
tool. But possible "hacks" would be:
- using -B with an outside line far below the horizon: but for this you 
require a 3d-modeler to setup the 3d model of the outside line, I guess 
this is not what you are looking for
- Using a height map which puts the outside terrain on a very low level, 
such that you cannot see it with the normal cameras
- Hacking trackgen: in src/tools/trackgen/easymesh.cpp, around line 
2270, look for exterior/interior, just comment out the undesired part

You can use ac3d, but this is not free...

Yes, Blender is as well hard for me, I think for a somebody using it 
often it is great, but just for here and then it is (at least for me) 
not that easy to use.
