Currently, mods which allow users to set dynamic/predicate-driven chestplate textures (of note currently are Chime and CIT Resewn) are indirectly incompatible with the chest size feature renderer, as said renderer has no way of knowing about the change to the displayed texture and/or model.

The request is either an API hook to allow other mods to tell the chest size feature renderer to update the armor texture (could possibly be applied to other renderer features provided by Ears as well, but this is the largest usecase I can think of rn), or some implementation of the chest size feature's chestplate support that can dynamically pull the displayed texure itself if enabled. The former is probably a lot simpler and less prone to breakages, since mods implementing dynamic armor texture/model changes may end up doing it in different ways.
