Do Touched Events work with Collision groups?

[Crysta1Egg (Robloxian)]

More specifically, can I have a part that does not detect another part with a Touched Event, if they are in different collision groups?.

Can you disable Touched event for parts in Collision Groups that don't collide?

Have you tried doing a check with CanCollideWith? http://wiki.roblox.com/index.php?title=API:Class/BasePart/CanCollideWith Simple code of BasePart.Touched:connect(function(hit) if BasePart:CanCollideWith(hit) then --code end end)
