1. Meshes are objects like for maps
2. Items are what people can wear
3. It isnt possible unless the person who makes the ears and manes and such for the games adds new ones.
4. You can't just make an item to replace a default
I'm not trying to gang up on you Bloo, cause ya know your awesome sauce, but I think this may be valuable for the future of helping people.
1. Not all meshes are for maps, there ARE ear2.mesh mane1.mesh ect. Take a quick peek in the models folder :3
2. Yush, Items are wearable peices of awesomeness.
3. I think you could actually, given the fact you COULD probably open the '.mesh' file in blender. I've tried once, and have succeeded. "I have discovered a way to control the wolf skeleton and make it do anything I want it to do." - SkeeverTail. It can probably be done with ears aswell.
4. Ears aren't items O.o they are things that MUST be added to your character, unless you delete the .mesh in blender, and put in little nubs instead...
*Wave wave* Luv chah blootiful bloo bloo
