Problems with track textures

[johnnascar]

Hi, I have been trying to create a Green-Screen track so I could record just the car but I have ran into some problems and I was hoping someone could help me or create a simple track.

Here is what I currently have: http://postimage.org/image/pjtvpb2ep/full/

The only problem is when I try to drive the car onto the green area it falls down a bit and spawns it in the grass as if it was falling out of the world.

Edit: here is what it looks like in-game http://postimage.org/image/qassyj2tz/full/

You've marked that area as "collideable" and not "driveable" so it isn't included in the HAT calculation. Very large triangles may do that too.

Thanks, fixed it now.
