Sprite Slicer is a tool that significantly speeds up the creation of image planes or sprites in Maya. It automatically generates the planes in the correct aspect ratio with perfectly aligned UVs. The smart algorithm in Bounds mode recognizes all separate shapes and creates sprites for them. Additional settings allow you to fine tweak the shape recognition.
The tool is also great for importing of reference images or any textured planes that will be used for modeling, for example hair strands, grass, leaves...
This is a demo of a plug-in I've recently put together for Maya. Primarily I had facial rigging in mind when developing it.
The idea is to allow users animate joint based rigs in much the same way that they do on blend shape based setups, using attributes to blend poses together rather than controlling joints directly in some fashion. I like doing facial rigs like this as you benefit from the speed and re-usability of a joint based setup but still maintain the nice layer of abstraction that you get from blend-shapes.
I've put the code and builds for Maya 2013 / 15 / 16 up on github for anyone that's interested in having a look. The rig is also uploaded there (meant as a rough example).
