What would be needed for projectile models?

[The Corporation]

Seriously, Do they need anything at all?
Do I need to just make the model, have it pointing a certain way, add anims if I want to, and export?

Or do I need to add something like detail32?
Please, this has been driving me nuts, and stopping me from fixing an addon.

It has to be on the Z axis, facing away from the axis center.

I don't know if you have to parent to detail32 (I don't use Blender) but I think it is safe to assume you do.

But other than that, no requirements. You only need to add a joint if you want to animate it.
