That's right, and I looked a bit at other vegetation shaders and I think the best way to to it is in another UV set or with a detail mask. I might use vertex position Y. Anyway here is a first look at The Toby Foliage Engine. Work is still in progress, especially the tree wind but it's good enough to showcase. I wanted to do a quick comparison with the Vegetation Engine, both in wind and shading. (Note this is in Built-in deferred) This shader is made to work by default with any model, vertex painting might not be needed but is optional. The wind even works with the model setup for the Vegetation engine despite intending a different setup so the shader does everything automatically. Still, if the wind looks a bit wonky and branches in the video seem to disconnect that's why. There is no vertex green in those models which I actually needed for my shader to work properly but I'm thinking of doing that automatically in the shader as well. Performance stats will come later.
