Does Blender no longer support Make Human file format? Does Blender no longer support the use of Make Human file format MHX1? 

The file type is changed from mhx to dae and the mhx file type no longer shows up in Blender as a supported file type. I mention this as I see some creators
point out the changing of Blender settings in their tutorial videos that no longer match the current configuration and it makes it more confusing .
The MHX1 format is extremely old and has been deprecated (in favor of MHX2) for many years. MHX1 should not be used, and no modern version of MakeHuman supports it. 

Contrary to MHX1, MHX2 is an add-on that needs to be installed. It is not bundled with Blender. 

How to get MHX2 support is answered in a MakeHuman FAQ, see http://www.makehumancommunity.org/wiki/FAQ:What_happened_to_the_MHX_export_in_MH_1.1.x_and_later%3F

Quick summary:


In a Blender + MakeHuman 1.1.x setup, you need to install MHX2 from https://bitbucket.org/Diffeomorphic/mhx2-makehuman-exchange/overview
In a Blender + MakeHuman 1.2.x (currently in alpha) setup, both the MH side and Blender side of MHX2 are shipped with the MakeHuman zip.
