^Sorry for the late reply, I forgot to answer ^^'. Anyway, you'll have to add materials to your track. Press m to open up the material editor, click the first material and make it a "standard material" and name it anything you like. Then drag and drop it onto your track. After exporting, the material should show up in the No limits editor so you can replace it.
Today I came across a new bug when I tried to import a coaster made with FVD. Basically the script crashed while parcing abbreviated numbers (3ds Max turned 0.000001 into 1e-06 and the unit conversion function didn't like this). I fixed the problem by letting the script set the system units to meters during the import process. This eliminates the need to convert the coordinates to system units and thus abbreviated numbers aren't a problem anymore. As a byproduct this also eliminates the need for 2 seperate files for dots or comma's as decimal seperators.
In short: There's now one script that should work for everyone and hopefully all the bugs have been solved
. Go get it in the first post.
