Came across Luchian and Lilski's posts on trees so I had a look at that and got the KSTREE_ block transform working. I didnt realize it but the trees werent showing up at all and after a little fiddling with directions and making sure the conventions were right it all showed up in Kseditor with the Block transform. those trees also had a bark mesh and so i didnt combine the meshs for the trees and trunk but used KStree for the tree mesh and combined all the bark meshes into a single object with a single texture. Ive been tracking the dip on a spreadsheet just to see what effect this is all having. bigger tree here has the shader and is part of block transform and has origin set. smaller one does not.
