Hello people!
Im stuck once again! I have a chain of bones - now i want to apply the xrotation of one bone to another. I managed to get the whole rotation by
multiplying both objects with their inverse parent transform
set the rotation and transform back (again with the parents transform)
r = $bone02.transform*inverse ($bone01.transform)
t = $bone03.transform*inverse ($bone02.transform)
t[1] = r[1]
--it works ifi set all three
--t[2] = r[2] --$bone03.transform[2]
--t[3] = r[3] --$bone03.transform[3]
t = t*$bone02.transform
orthogonalize t
$bone03.transform = t
however if i try to set only one part of the rotation the object gets skewed. I can orthogonalize its matrix but then the rotation isnt right anymore :/
Any help as always greatly appreciated!
