How can I have several models point to one parent model, so if I change the parent model, all the other models change the same way, similar to how array work and mirror.
All I want one model to “clone” itself to the parent.This way when I work with alot of copies on different places I only need to change one model instead of 40x because it’s very time consuming.
That is instancing, Alt-D to duplicate. Or ‘dupliverts’; set Duplication (Verts, Faces) for parent object, then parent Alt-P another object to it. This will become duplicated and will also allow for ‘modify one/change all’ kinda thing.
