How will internal parts of your creature be edited in late multicellular?

in my post about the view of the macroscopic world editor, the organ editor was mentioned, so I think it would be appropriate to mention it here.

It will itself be combined with the concept of the scale of aromorphoses for the formation of new organ systems, which I also spoke about before.

When this bar fills up, you can spend aromorphosis to develop from tissue (in the case of lungs, for example, there are three options from which they can be developed:

  1. They may be an outgrowth of the gastrointestinal tract
    2 They Can Be Developed From Gills
  2. They can be developed from pores or something similar
    ) organ systems, and then separate organs appear, which the player adjusts in the same way as he sets up skins in the skins editor mentioned in that post. The placement of organs takes place in the editor of the musculoskeletal system, when all other layers are turned off, becoming translucent, and the player places all this inside the body, while not taking the place of muscles or bones (the game does not allow this). The gastrointestinal tract, like the spine in Spore, is the main axis of the body, which, of course, can twist like the intestines of vertebrates, but, in any case, the body is built precisely relative to it.
