I tried the script you posted, but there's no change, DaBroOzer. Still, it seems to render better than with no script, but at this point I guess it's the tree models (like I said, even Loopix's are affected), and that in order to get the sorting working properly, they'd either have to be broken up into smaller pieces, or else the sorting would have to be done on a scale smaller than blocks (like vertices or something), since the blocks overlap and intersect each other.

I guess I'll see if I can somehow work with this limitation...

Thanks though.
