Is it okay to save multiple FBX files for different animations?

Unity Engine

Hi there,

Just wondering is it okay to export fbx animations to Unity in multiple files? Say if you have a whole bunch of model@anim.fbx files, is that going to create a big overhead?
Do people do that or is it better to put all of your clips into a single fbx file?

Also, in the docs, they mention pre-split animations Unity - Manual: Extracting animation clips
But how do you do that? Is that an export feature of FBX?

Thanks,
Pete

Yes if you are using the humanoid rig setup. You can also do it with generic as well - but I’ve not done that process so - can’t say if it works flawlessly. For legacy - idk.
If using mecanim you will essentially be ‘retargeting’ animations onto your character rig within Unity, even though the animations are created on the same exact rig.

To my knowledge - clips mean something a little different depending upon which 3D package you are coming from. From 3D Max this is essentially exporting a range of keyframes - which creates a ‘clip’ but I think this ‘clip’ definition in the documentation is referring to a Maya or Motion Builder term, where a range of keyframes can be defined as a ‘clip’ of animation and still be part of the entire fbx export. This is not a workflow/process available in 3D Max - don’t know about blender.

If you look back thru Kubold’s post history - we had a discussion about this -

Thanks man, I’d never set up things that way before but I think it’s gonna save a bunch of time :slight_smile: I’ll have a go and see what happens!

We have one FBX with the model and rig, which is used to create the avatar, then an FBX per animation. It works for both humanoid and generic.

Edit: It does work flawlessly for generic too, since there’s no retargeting involved anyway, the curves are referring to the same rig.

Does anyone have any pointers or tutorials for this? The Unity ‘help’ is typically limited to a few lines and a picture.
I’m having trouble with Biped on a single model in Max, every other mesh has worked, this one is a complete mess when importing motion capture (six hours spent trying to sort it - I now have to try something else).
I understand the theory, I just can’t get any sense out of it.
