Installation

In Blender open Edit, Preferences, Get Extensions, then use Install from Disk and pick the horse_generator zip.

Usage

1. Open the Horse tab in the 3D viewport sidebar (N). Click a breed picture to add a horse at the 3D cursor, or press Random Horse.
2. With the horse selected, the panels hold every setting: Body (breed, age, height, build), Coat (color, pattern, markings, dapples, mud), Hair (mane, tail, forelock, feathering), Saddle & Tack (outfit, saddle, pad, bridle, leather and metal) and Motion. Apply Breed Look sets the coat, hair and tack typical for the breed.
3. In Motion pick a clip (idle, graze, walk, trot, canter, gallop, start, stop, turn) to animate the horse in place, or switch to Path.
4. For a path, press Draw Path and draw on the ground in the viewport, or use Add Preset Path for a ready loop. Choose the gait and pace; add markers to change the gait or stop along the way. The horse follows the path and the ground.
5. The rig is a normal armature with IK foot targets and pole controls, so you can keyframe on top of the baked motion.
6. For game engines use Bake Coat Textures and hair cards.

The animation is stored as a normal Action and plays in any render engine.
