Animations from Maya to Unity

Overview

Exporting animations from Maya
Importing animations into Unity
Setting up an Animation Controller in Unity

____________________________________________________________________________

1.Export your character as an FBX file

enable your FBX plugin in Maya

Go to window>Setting/Preference> Plug-in Manager, Turn on loaded, and autoload for fbxmay.mll

Open the file with just the character rig,

In this file, we only want the Joints and the Geometry. (no control curves, no constraints)

We are not going to delete the controllers yet, since we don't want to mess up the rig. We bake the joints down to Geometry instead.

In the outliner, select all of the joints, we can do select>all by type> Joints.

Then ctrl select the Geo, do edit>Keys>BakeSimulation (Default setting should be fine)

now we can delete our controls, we would only have the Geo and Skeleton in our scene.

_______________________________________________________________________________________

Select all the joints and Geo,

use the game exporter to export the character.

Make sure

Select export selection,
if you have blend shapes set up for the character, check the blendshapes
uncheck the animation option box
choose the proper file path and name for your export

2.Exporting the animation

Open the file that contains the animation.

if it is a Cycle animation, make sure to leave out the last frame which is the same pose as the first frame.

I do like to bake everything down manually first to check everything works right in my scene.

Select the Geo and joints, go to edit> keys> Bake Simulation

Then you can delete everything except Character Mesh and joints, to keep the scene clean.

Select the Geo and Joints

Use game exporter

Select export selection
we can export multiple clips
choose the proper file path and name for your export

3. Import Character and animation to Unity

Drag and drop your Character FBX into your unity project Under Assets>Character Folder

Drag and drop your Character Animation FBX into your unity project Under Assets>Animation folder

To make the animation play on the model, we need to adjust couple of things in unity.

Select your model asset,

inspector tab, Rig

Animation type: humanoid (for a biped rig)

Sometimes. the naming convention used in your Maya rig might not perfectly match the unity setting, you need to configure the rig to make sure it would work properly in Unity.

(My suggestion here would be when rigging for your character, always read the game engine document first, and try to match their naming convention as close as possible. A name matching tool would be very helpful too)
