Unity 2017 has some great new features for animators like my self.
Most of all the Timeline feature.
In short the unity time line allows you to:
*create, play, and edit multiple animations on multiple characters and objects at the same time.
*edit audio clips together for your sequence.
*make more complex particle effects.
Basically Timeline is just like the timeline in a video editing software, but instead of editing audio and video your editing audio and animations.
This is a really powerful tool for people who like to make big animations on there avatars and/or maps.
And this feature would make the lives of many content creators so much easier.
I believe the addition of this wonderful feature to vrchat will open the door for many more content creators to start making these big beautiful animations.
