Hello! 

I've a problem when I import some objetcs from 3DXchange about the scale.
With some objects I can change the scale, and with some others I can't...! And I use the same options to export in 3DXchange...

This is a screenshot about a knife that I wanna "shrink". But when I do that, it only change the axis, and not the size. I don't understand why I've that problem with only some 3d models... 

I hope someone can help me! Thank you in advance.
