I made an orc mesh for a Glest mod a long time ago, and the current bestiary project got me thinking about it again, so I decided to improve on it.  It is also set up for rendering to a FLARE spritesheet, and includes multiple variations with different equipment.  The orc's appearance is loosely based on the orcs of Wesnoth.

Since this contains Clint's rig and animations, you must credit both of us and include a link to OGA if you use this.

The rendered sprite sheets can be found at http://opengameart.org/content/orc-flare-sprite-sheets

Edit: Fixed the shadow rendering issue.
