sorry for any incorrect terminology;
I want to make a low-poly octopus with a high-detail displacement/bump(?) map applied to the mesh. At the moment, I've completed the low-poly meshes for the body, and a single tentacle (which I plant to duplicate). I have not yet attempted to create any detailed mapping to either.
Because each tentacle is identical, I'd ideally like to do the details on one, make copies of it for the rest, and attach them to the body, so there is one smooth mesh with a smooth detailed layer.
My question: 1- Is it possible to join separate objects with their own displacement maps together as one object with a single displacement map?
2- If not, what is the best way to handle this task (without manually detailing each of the 8 tentacles)?
