Hey peeps, I forgot to include this part of my Unity section of my tutorial series. This shows how to properly export your FBX from blender. I'm also updating the Unity video to include this part.
Edit: I forgot to include where I applied all the mirror modifiers to each object and joining the meshes together.
- Apply all mirror modifiers to each object.
-Either Drag and select or shift-select each mesh and then ctrl+J to join them all together. Name it whatever you like, I just name mine "body".
I'll post an updated version soon.
