Thanks for the answer.You won't be able to "morph" into an NPC. It is likely that you can wear the existing npc meshes as a modded customization item. I think I may have explained the possibility of doing that in another thread.
Sandbox+ was able to apply preset outfits with keycombos. If you could create the NPC face and body as clothing items that obscured the player, it would be possible in theory.Thanks for the answer.
Alright, cool.Binding keys to just switch, don't think so, but mod away I suppose.
I can't say for sure if you can create new entries or if you have to overwrite existing ones or not. Someone else on here may be able to chime in on that one.
