Hello, I was working on a quadruped rig recently using rigify samples, and thought it will be good to share it here as a Metarig.
Apparently it’s possible to save Metarigs using the “Rigify Encode Metarig” function when hitting space in edit mode.
would be nice also to commit it into blender but not sure how, and who is currently maintaining rigify.
would be even better to have some library that people could upload and share their metarigs. maybe with the cloud?
The WGT controls could probably be scaled and moved, but I would let you do it yourself via the WGT objects.
you can download it from my github
Download Quadruped for blender 2.77
and
Download Quadruped for blender 2.78to use it just right click save as, and then copy the py script to the folder in
\scripts\addons\rigify\metarigs
on another note
If you want the spine to work really properly, so that all the bones stretch equally and not just the 2 middle of them as it is now. then you could also select the spine bones in edit mode and then use my script to create spline from bones.
this will create a new armature with only the spine bones attached to a curve and hooks, the hooks you could link to the bones in the original rig. SplineIK in blender has dependecy issues and is working properly only when using it on a separate armature (could be part of the deform armature).
hope it was somehow clear.
