About once a year, I start learning and modelling again. I fear that the following requirement is not possible:
Create 4 pieces of wood (4 objects), select them all, create a composed object (no, not join) and name it “bed”. The pieces’ relative position is now locked, so I can grab the bed as a whole and put it anywhere. I want to create multiple instances of this bed and place them whereever. The bed always looks the same. If I unlock the relative position (rotation etc) of the 4 pieces, I’m able to change the design of the bed. All instances still look the same.
You see the problem: I can’t create “a bed”. This level just does not exist. I mean a composed object with individual but glued objects. Isn’t this a basic task? Create a model and put several instances (not copies!) into the scence? If you change the model, all instances change their look because it’s the same model. I can’t imagine that you copy everything and have to do all changes for every copy again and again.
(Whenever I want to display the same object several times in D3D, I just change the transformation matrix between rendering the instances. I wouldn’t want to copy all object data. I also don’t see a kind of frame hierarchy in Blender.)
I must have missed something.
