How to get the Block Avatar's asset IDs

[134679qQ258 (RCSH)]

I want to replace the player’s character appearance with a Block Avatar’s torso and limbs. But I don’t know how to get the Block Avatar’s torso and limb IDs

Simple answer is you can’t. The blocky rig is just a fallback model, and as far as I’m aware, doesn’t really have an ID for the limbs.

You have to write a script that gets the HumanoidDescription of a character and overwrite the limbs with the AssetId of 0.

Alternatively, if using R15 and you don’t want to have the hassle of writing it yourself, just use the S15 Bundle Model because it just looks better.
