How do I change 3D models like trees in Pokémon platinum using Tinke?

[WalkTheWalk]

I'm trying to make Pokémon Platinum look all haloweeny by changing a few models and the first one I wanted to change was the trees to make them autumn colored, but there 3D models with a .BMD0 file type. Tinke doesn't seem to have an easy answer on how to change the models so can I get some tips?
