I'm struggling to precisely align two unwieldy high-poly meshes that share an overlapped region. My approach is to pick three common points of interest in the overlap, create null objects at the three locations on the respective meshes, then snap align the two sets of null objects only using translation, allowing the rotation to follow the triangulation between the three common points. My understanding is that I use pointConstraints, and assign attributes in the Node editor to translation, but I'm a total newb, can't find any tutorial or Help instructions guiding me through the steps of bringing up my meshes, nulls, etc. in the node editor and how to connect outputs to inputs. Well, I am finding pages, but I get lost around simple fundamentals in the language, would greatly appreciate a helpful hand. Thanks in advance.
