Making players able to walk through a zombie humanoid

I have got a zombie from the marketplace, but I can’t figure out how to make it so that players cant collide with it, and also I can’t figure out how to make it so that the zombie can walk through walls.

Hi, I tried collision groups but the zombies still collided with everything (parts and players)

#4

have u put the right part in group? some parts of the zombie dont need CanCollide true, only the humanoidrootpart, and put that humanoidrootpart into collision group

local Workspace = game:GetService("Workspace")

local function MakeZombiesNonCollidable(zombie)
    for _, part in ipairs(zombie:GetDescendants()) do

            collisionGroup.Value = 1
            part.CustomPhysicalProperties = PhysicalProperties.new(0, 0.3, 0.5)
            part:SetAttribute("CollisionGroupId", collisionGroup.Value)

Hi thank you very much, I ran this code and got this error:
‘Unable to create an Instance of type “CollisionGroupId”’
Sorry i’m quite bad at scripting so not sure whats wrong. I put the code in server script, is that right? Or should I put it in a local script
