Well as I understand it.......
If you have ModelC 0.8 or above you make the tree by hitting the "Make Tree" button in ModelC. This gives the error when I try to save the tree (Error loading bsp.dll)
But without ModelC 0.8.....It's says you need HCI's Tree Builder...after you save your IFF, you copy...The Vert/Face/Vtnm/Fvrt.wcp files into there own directory with HCI's Tree Builder. ... in Dos Mode you type Tree.exe (to whatever directory you shot those into) then hex edit a few lines. Then go along with adding turrets etc...blah blah blah (The Easy Stuff)
What I'm not following is I can't do it the easy way by using Modelc0.8 so I have todo it the hard way (Which really isn't that hard) but where do I find HCI's Tree Builder...Because I can't find it, There's Tre maker but that's to make the .tre files which have nothing todo with a collision TREE. Then there's Tre manager which is used to extract files out of the .Tre files. But I need the TREE Builder.... and without it...I'm SOL
