Hello, I've been trying to modify the human models of Containment Breach but I've run into a problem. It seems that the scientists, D Class, and Janitors all use the same model and that's classd.b3d. Is there a way to duplicate these files and assign each human npc to their own model so I can edit them? For example, putting hats on only the janitor NPCs?

I've tried to modify the source code of the game but I'm not sure if I've done it correctly, it's all pretty new to me.

Yes, it's possible, you will need to modify some code, however. Copy and paste "classd.b3d" onto another file, and edit it as you like, (giving it a hat) and then go into NPCs.bb. Inside NPCs.bb, you'll need to find NPCTypeD and copy-paste it's code again, renaming NPCTypeD to NPCTypeJANITOR or something. Once you do that, you can assign the modified model you made in the code, and replace the 2 events featuring Janitors (endroom, and room2elevator2) with the modified model

I made the model and put it into the npcs file and added NPCTypeJanitor for Janitor. What do you mean by "Assign the modified model I made in the code?" and where do I find the events where I replace the models?
