one tiny happy thing: if you remove the wait(1); from the end of the while loop, it works fine, but much faster.

moreover, I wrote a small addition that creates the compilation option string based on actual sun ambient and fog colors. I will post it here tomorrow, really simple.

and finally I could integrate it into my MapBuilder editor. I made a short script that recreates bounding boxes and attached decals shadows too, using the tricky approach I mentioned here earlier.

but as I see lod models do not work (having the same name with different endings: *_0.mdl, *_1.mdl, *_2.mdl, *_3.mdl), but don't know why, I think they should work.
