Thank you so much vig :D resetting the scale and transform fixed all the wierdo scaling problems I Re rigged the leg from scratch and linked everything but now i have this wierdo tiny error . "the objects With *look At Constraints* dont rotate with the the rest of the leg as I move the Hi Solver forwards and backwards"
It looks like you solved the rotation problem in first video? In the second video, it looks like you want to rotate the entire leg from the base? You can do this by adding a parent to your leg bone, a dummy or a point helper should work pretty well. You'll rotate the helper to control the angle of the leg and move the tip…
I watched the first video, if the next two are anything like the first, they aren't very helpful. Got a link to the tutorial that might clue me in better? It looks familiar but youtube obscures the link. This is one of the reasons I think youtube sets people up to fail. It's possible to say a lot of stuff but not really…
