Hi, i have a tree model, from blender i did export it as a .obj.
Model is not a single object, it has six difrent separate mesh. (bdw, i also did try the joint the meshs and make a single tree object, but it still did not work.
well, these little a minute videos showing what i did try, its better to understand the problem this way.
