@menithal and HF developers. All static properties of an entity need to be settable as part of an entity’s upload; that is, it needs to properly support in the model. This is true for entities, this is true for avatar models. Yes, registration adjustments can be done after the fact by a script (event the standard edit script). That there are such workarounds is no longer a proper excuse for a beta level product.
Either get the system architecture fixed now or this product is going to suffer mightily when these huge inconsistencies have to get fixed later when a ton of content has been created.
This is a great time to go through everything and to ensure that the architecture is consistent and correct. Every day that goes by with more hacks makes it that much harder to make the product jell properly on its way to production status.
