I have a rather large multibody part file that I am trying to set materials for. Last night working at home, I was able to set 4 of the bodies' materials to aluminum early on in the modelling process. Now that there are 16 bodies, the material option for bodies is not available in the right-click menu (see attached) on either my home computer or the one in the shop. The 4 original bodies are still set as aluminum, but I cannot change/remove this or add materials to the other bodies. Does anyone know how to get the material button back for my part and how to prevent it from leaving in the future?
