Need help with colliders

idk if this is the right category for this but im trying to make a world with a desk with some pick up objects with a box collider and the desk has a mesh collider is there any way to make it so a player can walk through the desk but the pick up objects still collide with it?

The Walkthrough layer does exactly that.

how do i get the walkthrough layer? sorry for the dumb question

If you don’t see it in the layers menu, add the VRCWorld prefab to your scene, then go VRChat SDK -> Show Control Panel -> Login -> Builder -> Click the button that says you need to add layer and matrix
