Thanks for feedback and critique!
@Sitrec, about “Saintpaulias”, this one is European specie, and leafs are wrinkly, and some leafs are fluffy. About poly-count, I will probable do that, there are over 120 meshes, lots of text to put somewhere:)
@MooseCommander, some normals are “aggressive”, but this can be changed very easy. Also the roughness can be changed with a click, depending on how you like the final model to be, I don’t see any rendering issue here, you can tweak the material as you like, roughness, even color for more variations.
About photo sourcing foliage, so far I think is the best way to do it. You recommendation with high-poly versions and bake work only in some scenarios, because you lock your geometry to a shape. By example, most of models in this pack support material exchange, meaning, you can use same mesh but change different leafs/flowers material. This was my intention also, to do not lock leaf/flower geometry.
