I’m looking for a solution to a problem. I use blender to teach 3D modeling in middle school technology classes. One of my students is following a tree tutorial found on youtube and has found that the sapling add-on UI menu disappears a lot. It always disappears when he loads the saved file, and it often disappears when he deselects to tree object, but does not reappear after he reselects the tree. How do you find a missing UI? Has anyone else used the sapling add-on and seen the same results? Suggestions?
