3DSMax FBX -> Unity (Bone Animations)

Hi, So i've been googling and searching around like crazy but couldn't find a solution or anyone who has been experiencing the same problem as me. Basically, I created a character in 3dsmax, created a rig and weighed the character using the skin modifier. I then proceeded to animate the character using FK and IK controllers. Mesh + Rig

Then I selected only the bones and collapsed the trajectories (as read from Unity Docs). Animation still looking fine here.

I then export it to Unity and it just breaks..

It seems like the hand IK/FK animations are just completely lost, the pelvis/spine/neck/head don't move at all. Only the leg animations seem to work reasonably.

Also it seems like the animation is below ground, because when I check IK in Unity, this happens.

I have absolutely no idea where I went wrong here..

I have tried the following stuff: - Skin Modifier, bones affected set to 4 - Unity quality, bone weights set to 4 - In 3dsmax, motion->trajectories->collapse (frame 0 - 130, sample 10) - FBX Exporter options: ASCII, Binary - FBX Export Options: Version 2009, 2010, 2011, 2012 - FBX Export Option: Bake Animation

I'm at a total loss here. If anyone would have any information on what i'm doing wrong here, i'd greatly appreciate it!
