Larian Studios Forums Divinity - Original Sin Divinity - Original Sin - General Question about modding and adding 3D content

I'm particularly interested in all this, though it'll be a complex task.
Given the fact we can't use Granny 3D (unless you're rich), I guess Havok Animation is the best solution at the moment.
What about special effect, anyway, such as spells ? Will we be able to import our own particules/effects to the game ? I know I might sounds stupid to ask this, I don't know much about modding (creating a 3D model and animating it, I mean), but are these kind of things considered 3D objects (animated), or classified as a different thing which require another format ? If yes, which software (and format) does it require ?
