My version of the Gmod ponies for Blender, based on "Cheerilee's Gmod Ponies" package. Originals are licensed CC-BY and therefore re-uploaded legally. Improvements in my version include:

Version 3.0 (18-12-2012):

• All ponies are rigged (apart from Luna and Celestia since they have different forms, will get to them later). Facial expressions can also be animated.

• Old eyes replaced with deformed spheres, which allow pointing toward a specific look direction without changing form. The original eyes are also available on another layer.

• Shared mesh data for all objects that use the same shape. This should reduce file / memory size and as well as make it easier to edit the ponies.

• Pin vertex groups for manes and tails, allowing cloth simulation in animations (not for Luna and Celestia yet).

• Subsurf all objects for higher quality, only visible at render time.

Version 3.1 (12-08-2013):

• Rigged Celestia & Luna. Also give their mane and tail cloth pinning weights.

• Reduced polygon count for excessively high-poly models.

• Fix bones and weight paint errors in various places. Facial expressions are also much more flexible and configurable.

• Bone constraints, to keep pose deformations within correct limits (disable if animating broken limbs).

• Bone shapes (looks nicer and makes posing easier).

• Default walk animation included (moves 1 blender unit per loop).

• Optional freestyle configuration, allowing for original MLP-FiM lines and shading.
