Help With certain Collisions

Hello, I’m trying to make it where certain blocks cant collide with certain walls, i know there is collision Groups but it never works for me, is their a script i can use to make it where certain blocks cant collide with certain walls? Or I can put a script in the block i want to effect?

Check out CollisionGroups to make certain blocks not collide with certain walls.

i got it to work from using the script thank you
