Got custom objects with animations working. Only trouble right now is getting collision working.
Game checks for the object ID in a binary table and if it doesn't find it it won't load the object. Making changes to that table gets the object to load and animations will work just fine, but I still have to figure out how to get the game to load the collision files when included.
There must be something missing for this custom object ID still since if I put another object in this slot the collision files load correctly.
