Inverse kinematics on makehuman models in unity

I am trying to implement inverse kinematics using one of the assets provided in unity asset store [Bio IK] (https://www.assetstore.unity3d.com/en/#!/content/67819) on a model exported from [MakeHuman](http://www.makehuman.org/)
I tried to follow the demo scene provided in BioIK unity package and also one of [IK Tutorials on youtube](https://www.youtube.com/watch?v=EggUxC5_lGE) However the structuring of the model is different in the one exported from makehuman and the one present under default unity third person controller standard asset.
I am able to rig and animate the makehuman model as explained in [this youtube tutorial](https://www.youtube.com/watch?v=i7a_wlAKB7I&t=514s) however I can't figure out how to implement IK on a makehuman model successfully.
Please let me know what it is that I am doing wrong or some link to a tutorial which explains about implementing IK on a makehuman model inside unity.
**Sidenote**: I came across a few forum questions such as [this one](https://blender.stackexchange.com/quest ... ender-2-78) which explains about implementing IK inside blender using mhx export format but it was also mentioned that is only for blender and nothing else.
