I've been making new units, officers, mounts, weapons and missiles successfully, but somehow can't figure out how to create new animals and have it use the variant mesh that I want.

The problem I keep running into is this:
- I've created a new animal in the animals_tables and battle_entities_tables
- I've created a new variant mesh definition for the animal
- I attached his new animal to a land_unit

When I start the game and use this land_unit, the new animal will not have a model and won't be visible -- even though the unit highlight circle can still be seen and the unit actually works.

So the question is: how do I get the new animal to use the variant mesh definition that I created?

TIA
