I've downloaded a tree object and it is already a polygon (already editable object). I want to animate its size like it grows from small to big - maybe the tree pops up. What I did is I tried to select the whole object and select the scale tool. I created a keyframe by clicking the Record Scale, position and PLA of active object tool. However, it didnt seem to work. But using this with primitive cube, etc works. How can I animate the size of the tree object? Im using a mac and cinema 4d r12.
