bh_waveIt is a new animation tool for Maya which speeds up the process of blocking in simple wave motion for things like tails, capes and anything else that might need it.
Here's a quick demo of it used in a broad way on a few different rigs :
For an overview of how to use it please watch this video : https://vimeo.com/279434632
I've also made a video demonstrating how I finesse and polish the animation when creating looping wave cycles : https://vimeo.com/279436312
I'll also be adding more videos to my Vimeo channel that will go more in depth into some of the advanced features soon.
