SOLVED Tree branch/leaf collision

I explain the issue below the fix.
SOLVED! I'm pretty sure. Basically, i copy the whole asset tree so "/levels/myMap/art/shapes/trees/trees_douglasfir"

In the trees_douglasfir folder I have the main.materials file copied from driving center map. (nothing else, all DAE files and textures are references from driving center map ZIP file)

And the important bit is in the "/levels/myMap/art/shapes/trees" folder, you need to copy the main.materials file from the driving center map here, this is what defines materials collision types... for some reason.



This is working for now, ill update if clearing cache or making more changes messes it up.



So I made meshes and brushes for the forest painter via referencing the DAE files from the ETK driving center content folder. So I don't have the models or textures copied into my mod folder, just the materials folder as textures didn't show up otherwise.

I am adding a video demonstrating the issue of branches and leaves being completely solid when ported over. Any explanation or documentation would be greatly appreciated. Thank you for reading!
