Converting Unity Transforms to Blender

I made an animation that sheathes sword, but sword and sheath are independent objects, i set them parent to the hand and rib via script. Now i want to put sword back to the sheath accurately, but for this i must attach sword child to hand inside blender with correct transforms. But when i enter transforms(which i used in script) to blender(being aware of Y-Z axis differences) it’s doesn’t put sword to correct location and rotation. I think it could be because of different scales, but i don’t know how can i overcome this.
