How would I add multiple collision groups to RaycastParams?

Im currently making a door that you can shoot open and open with an interaction system, both of them using a raycast. I have a hitbox that I do not want the gun to detect and I used a collision group to fix that. However, the interaction system does not work on the door. I’ve tried using a table but it only accept strings

	local raycastParams = RaycastParams.new()
	raycastParams.FilterType = Enum.RaycastFilterType.Blacklist
	raycastParams.FilterDescendantsInstances = {character}
	raycastParams.IgnoreWater = true
	raycastParams.CollisionGroup = {"Default", "gunignore"}

If this isn’t what you’re looking for and you can’t find any working sources I recommend using a different method for finding all instances that you don’t want to have detected. an example is Collection service getting all the instances tagged with a specific tag and then inserting them to a table then adding that table to the blacklist with character

Yeah, that seems like it. Thank you!
