Blender Development
Blender is an open source, 3D creation suite. It is a beautiful program that can do a surprisingly large number of things, from 3D modeling and animation, to vidoe editing, to painting and image manipulation. What makes it even more powerful is that it's easy to develop for. Moo-Ack! Productions has worked on a few blender addons, listed below.
Minecraft MCprep addon
This is a blender python addon to increase workflow for creating Minecraft renders and animations, by automatically setting up better materials, importing library models and groups, and setting up proxy characters for animation and default animations for regular features like grass and leaves on imported 3D minecraft worlds.
Blender Effectors
Blender 3D addon for special motion effects for groups of objects, inspired by Cinema 4D's shader effectors.
Pose Tool
This is a blender addon which hosts a few tools for improving and extending the use of the blender pose library for character animation.
