No collision npc

I made an npc from a rig and how do I make it that you can walk through it?

Make CanCollide in all parts False

Utilize Collision Groups. If you use the built-in collision groups editor properly, it can definitely help you. For example, you can have your npc collide with the map, but it won’t collide with the player.

This is a good Collision Groups Editor tutorial

Try that Search button up top. I know this subject has been covered quite a few times in other posts.
Use different terms like ‘make npcs not collide’ or ‘npcs non collide with each other’.
