Horses, future spawning system

Adding, Removing, or Changing

Adding

Type of Modification

I want to ...make horses have a specific color / pattern in a set biome / region

What are you trying to modify

The way I would implement this is to set these https://www.digminecraft.com/lists/horse_variant_list_pc.php and make them configurable in iris per biome and region.

Maybe add support for custom models for resource packs or something similar.

Alternatives

If this could not be implemented I would do nothing, might be a nice addition

You can currently do this through scripts, which is significantly more difficult than a normal config setting, but still possible.

Instead of implementing this (quite niche) suggestion I would recommend implementing raw string NBT support (so one can set {Variant:###}, in this case). This allows support for all current and future NBT settings not currently accessible (i.e. villager trades)
