I'm importing a model, and the whole model is joined. I'm trying to separate the model's parts I got a model from ripping a video game, but the model has separate parts/object groups that I want to separate.
Sorry for the abruptness of this post.
In order to seperate parts a mesh, go into edit mode on the object in question, then either right click and select seperate, open the quick search menu and type seperate, open the mesh menu in the top of the 3D viewport and select seperate, or use the hotkey [P] and select seperate by loose parts.
You can also seperate individual pieces by selection, I noticed that you have vertex groups for the different pieces, which would allow you to easily pick which parts to seperate.
