No transform and delta scale are 1. This issue simply stems from the problem if the importer of the fbx removes the amarture root object without transffering the correct scene scale to the contained root bone the scaling just defaults to some random scale.(in my tests it wasnt even a power of 10 scale, i think that it takes the maximum dimension of the bounds an defaults those to 100 and everything just gets way to large.- the scene scale written in the fbx on export gets lost somehow…when importet in 4.16 and above.
