Is it normal to have warnings from the default animation script for using a custom animation?

So I made a custom character alright?

Now the Custom Character does not have a Torso but it does have a HumanoidRootPart

of course

so it gives me the warning that the Torso does not exist

Im wondering if this is normal and if I can get rid of the warning or make the torso not a requirement somehow

I tried adding the torso then it throws more warnings like RightShoulder attachment missing or something

Apparently in line 2 theres a line where the script waits for a child named Torso

Also what is needed in a custom character

I know that the HumanoidRootPart is a must but is there anything else?
