Quadruped walk/trot cycle
 
This is probably one of my most complex tutorials. If you want to learn how to make a quadruped walk cycle you need to make a biped walk cycle first then do it twice and offset the time by around 25% or so, depending on the walk style you want.

Quadrupeds are very complex and can walk, trot, run, march and many other movement cycles and each one of those have completely different patterns.

For reference here's some cool stuff:

I hope this helps :)

As always, thanks for the support!
