Player only collision

I am using custom models for my characters; the issue is that I need the players to collide with each other but every time I turn on collision it causes issues with walking etc. I would like to make collision off, so they don’t collide with anything except for other players. How might I achieve this?

Well, you’d have to script it. So, my recommendation is to google it up.

You can use PhysicsService.

for _, BodyPart:BasePart in Character:GetDescendants() do
    if BodyPart:IsA("BasePart") then
        PS:SetPartCollisionGroup(BodyPart,"Players")
    end
end
