Motion Capture T-pose Bent At Hips As part of a larger project, I created a simple human mesh in MakeHuman, enabled MoCap with it in MakeHuman, and imported it inro blender as an FBX file. 

When I 'Load and Retarget' the .bvh file I want to use, the model/rig dosn't go into a t-pose as it's supposed to, it is bent at the hips. This totally screws up the animation, as it looks like the figure is always leaning over. This happens with all the MoCap files I try.

I tried going into pose mode and bending the hips back into a normal position, but because the hips are constrained, I can't find a way to do that. I've re-made and exported the .fbx file, and re-downloaded the MoCap files with the assumption that it was just the files that were corrupted, but the problem persists.

Here's a screenshot:


The guide I've been using to do all this is this video by Remmington Graphics.

The MoCap files I'm using come from this site.

What is causing this issue and what can I do to fix it?

Thanks in advance!

Here is the .blend with the extra files packed into it: 



EDIT: Here is the MoCap file, a FBX file and a DAE file.

The video author is using Blender 2.77a, you are using 2.79. This is important since Blender got a few tweaks on importing Collada files.

I am using 2.79b and tried to replicate your problem. I don't get the same problem but I do get issues when importing Collada if I do it the way its done in the video. I was able to solve it with this setting:



This fixed my issues, I hope it fixes yours.

Steps taken:


Exported character from MakeHuman as Collada file with Mocap skeleton
Imported Collada file in Blender with the "Auto Connect" setting
Selected the skeleton. Made sure its in Object Mode
In the MakeWalk v1.1.0 panel, pressed Load and Retarget and selected the Mocap file
Played the animation




It is also worth noting that I downloaded the "Daz friendly" version of the Mocap Files.
