.Net 3.5 to 4.6 Upgrade --> messed up scales at Collada Models

Hi Everyone,

I am working on a project where we import Collada data into Unity at Runtime. It is an older project and used to run on .Net 3.5. However I wanted to upgrade it to 4.6 to use some different Libraries.

Now the Import still works but somehow the scale of the objects is messed up. Everything is factor 10^6 bigger than it should be and the quaternions are also wrong.

Does anybody have an idea what the reason could be? Was there a change in the .Net Api or did Unity change something at their scale factors in the .Net 4.6 versions?

I could not find any solutions so far, so maybe someone can help me. Would be very appreciated. Thanks a lot :)
