I know that we can/could export terrain to 3ds but with track included? Are you sure you didn't do that with the nl construction kit? But, nlck would deliver higher quality.

Thanks a bunch, I found it. its on the toolbox page near the bottom. Its actually a project for school... hopefully I will get it to a point to where I can show off what all I want to use this for.
If it's a 3ds (the pic you posted) then I'm pretty sure it's from one of the older terraformers, I still have the last 1.3 version and actually use it pretty often.
