Here are a few random/useful tools that I've either written or compiled.
Alembic 1.0.4 Mac Plugins (Maya 2011 & 2012, Mac 64-bit)
Alembic is a joint venture between ILM and Sony Pictures Imageworks to develop a universal 3D data interchange format, and it's catching on very quickly.
This is a Mac build of the (rather rough around the edges) reference plugins for those of you who don't want to fight with getting all of the dependencies & out of date ILMBase to build properly.
In order to use the plugins, familiarize yourself with the MEL required in the Alembic Wiki (there's no GUI).
From Maya 2012 Subscription Advantage Pack onward, Autodesk is including their own build (no GUI) of Alembic import & export in Maya (1.0.0). These plugins are really aimed at early adopters and folks who want to hack around a bit before they get their hands on a more full-featured solution.
Mix20Layers Mac (Maya 2011+, Mac 64-bit)
My compile of Jan Sandström's Mix20Layers shader (itself a modification of ctrl.studio's Mix8Layers) for Mental Ray.
The shader allows you to combine other shaders' output with Photoshop-style blending modes.
