Hi,

I am trying to get the inverse of a bone transformation, when i use !m (where m = bone->GetMl()) I get incorrect values. since multiplying the result with the original matrix (the one that the inverse was obtained for) doesn't return a unit matrix ... in short, I found that multiplying a matrix by its inverse doesn't return a unit matrix. so this means that the inverse of a matrix SDK code has a bug in it ... any ideas ?
