Bake high poly onto multiple instances of low poly

Question

Hi,

I have created a low poly and high poly palm tree in Blender. I have a trunk and a leaf and can successfully bake the high poly versions to the low poly by mesh name (suffix _low, _high). This tutorial (https://www.youtube.com/watch?v=TtpV-RsEJvI) suggests it's possible to compose the full low poly tree with multiple instances of the leaf poly and bake the high poly to that fully composed one and paint within Substance 3D Painter as a final product. However, when I import the full low poly tree, the bake does not work properly - I think because the suffices no longer match the names. I have tried naming the leaves:

Leaf_low1, Leaf_low2 etc. or Leaf_1_low, Leaf_2_low etc. but neither seems to bake correctly.

Any suggestions?

Thanks!

Daniel

Hi,Thank you. So according to the documentation whilst multiple high poly can be baked to a single low poly it's not possible to do that the other way around (unless I am missing a trick). However, I've found a solution - provided that the high poly overlaps one of the low poly and each of the duplicated low poly share the same UV map and id color, the bake is used across all of the low poly.Kind regards, Daniel
