I did see in the Rules they are not allowed, But I've seen a couple people using them in their runs, so i want to make sure incase i submit a run so it wouldn't get rejected

A run with custom models/outfits would be rejected

There’s nothing stopping you from using them for your own personal runs if you’re practicing. If you plan on submitting it’s best to do so without them.

interesting that they are allowed in resident evil runs but not silent hill.
