The Create Ortho image, still uses the second spdtree folder, C:\Hitech Creations\Aces High III\ah3terr\avaeto\terrset00\spdtree\swa\spdtree\swa to load the tree file.
Thanks
EDIT: Actually, now it won't load from anywhere!
I've sprinkled the swa file throughout the path in combatw but no joy so far. Will try seeding the swb file next.
C:\Hitech Creations\Aces High III\ah3terr\combatw\terrset04\spdtree\swa\spdtree\swa
Nope, still no joy.
