MHX Mocap Add-on in Blender 2.58 installation problem

[pa3kp]

Hi all!
I'm having an issue linked to the installation/use of the 3D View: MHX Mocap Add-on in Blender 2.58 (2.58.0 r37702) on Windows Xp.
It's easy as 1,2,3: when I open User preferences... in Blender and try to install the add-on, nothing happens. When I click the checkbox 3D View: MHX Mocap, the checkbox is dead.
I installed 3D View: MHX Fourier and 3D View: Makehuman pose tool without issues.
I installed the "problem making" add-on with no issues in Blender 2.57.

Can somebody help me?
Thanks in advance!

This is probably because the location of the ImportHelper class (which filters out bvh in the file selector) was moved. Fixed in svn.

Same problem.
What can I do to fix it?

[ThomasL]

Download a recent nightly build, http://download.tuxfamily.org/makehuman/nightly/

Or revert to Blender 2.57.

Hm-m. I've tried to use Nightly build but there're some errors with export, same as with standart Blender ".mhx" importer.

Hi. I had the problem you mention, and is really easy to fix. All you have to do is go to line 87 of the space_view3d_mhx_mocap.py file (that I assume you alredy have in your /addons folder) and where it says
from io_utils import ImportHelper it sholud say:
from bpy_extras.io_utils import ImportHelper
That fixes the problem. Now save and intall the addon normally.
Hope it helps

Thanks so much! It worked like a champ! Why does my 1.0 Alpha 6 version still has the old tool and not the new tool?
