I'm still pretty new to blender so no hate. I have a quadrupedal rig that I built from following an online tutorialTutorial Here! I am trying to find out how much of the processes in this video are necessary because I've seen and read about different ways.
In the tutorial, and in my blend, the IK limbs ended up twisted. He corrected his. I'm not able to as well as he did. Is there a standard way to prevent this in the future?
I set up pole targets, but how necessary are they really? I've seen rigs do without them and they seem to cause confusion(at least for me). Do the pole targets cause the twisting?
Finally, I have placed the IK constraints on the upper limb, as the video instructed. Is this best or is it better to use the lower limb?
Also, if anyone has any better suggestions for learning material on this topic I'm open to it. This was just the most recent tutorial I could find.
