The Lonely's tute is for 3d studio max primarily, aside from the text editing, so you'd need 3dsimed too i think to get the track looking reflecty, which isn't covered (for 3dsimed) in The Lonely's tute, though some of the concepts are the same, and _all_ the text editing is the same. I think the 3dsimed stuff might be covered in another thread here.
And the rain.gmt idea worked a bit, but it didn't work when looking sideways. i had a try, but didn't even get that far. that thread is pretty fresh currently, maybe only page 2?
