Is there a way to calculate the tangents of a model in the material editor?

Well, you could bake initial orientation of your leaf cards into something like additional UV channel or vertex color and use it instead of vertex normal.

I thought of that but because I use the same texture on all the leaf planes I have to overlap the UV’s in the first channel. If I flatten all the planes and put them in the second UV channel they don’t line up.
