Problems importing MHX to Blender

[TheXtreme76]

hi, I use MH 1.0 alpha 5 and Blender 2.5 alpha 2. I'm having problems importing MHX files into Blender. I installed the addon from blenderartists.org. The addon file came with a couple example MHX files. Blender imports them fine. but when I create a new file in MH, nothing happens, and I get the message:

Please help...
There's also a problem when trying to import obj files from MH into Blender. the mess looks almost normal, everything where it should be, but the mesh is actually broken into small segments. Has there been a fix for this?

Thanks,
Michael

if you don't want groups in the obj mesh, uncheck the groups button when exporting.

Sounds like a compatibility problem. Both Blender and MH are alpha software which change continuously. Try to download the most recent nightly build of MH and a recent Blender build from www.graphicall.org.

Blender's obj importer can either create a single mesh or separate objects for different groups. Turn off the group (or maybe polygroup) option when importing into Blender

Blender .obj importer has some bugs and problems when importing curves. I am modifying the obj importer for Blender 2.49b and 2.5 so it would work with nurbs. Unfortunately I am puzzled by a few things. Thomas, you have apparently implemented your mhx importer in blender. In Blender 2.49b how were you able to have it work? if I modify import_obj.py in the .blender/scripts directory of Blender program folder, blender will NOT recognize this script if I go to File->Import->Wavefront (.obj) .. so to me, this seems that the importer is coded internally in Blender 2.49b and the program does not directly use the script files it has available for the user. I want to confirm this, and I want to know what you have done to make the .mhx to be diplayed in the Import menu of Blender.

Hi Jose.
The import menu is only modified in the 2.5 version. The code that does this is at the end of the 2.5 import script. It is fairly standard; the built-in scripts access menus in the same way.

The mhx importer for 2.49 uses an old-fashioned interface with buttons.

I'm also having problems importing mhx to blender... but I never used blender before so there's a big chance I'm doing something wrong.
I'm using a MH build from yesterday (22.06.2010) and a Blender 2.5 alpha 2 build also downloaded yesterday from www.graphicall.org (2.52.5 r'29574'). I did also try an older version of blender 2.5 (the one from the download section of blender.org) but that didn't work ( no module mathutils error).

I copied the scripts from makehuman\importers\mhx\blender25x to blender\.blender\scripts\io, blender started, no error reported, but when I try to import a mhx file I only get this:
RNA_string_set: IMPORT_SCENE_OT_makehuman_mhx.filename not found.
RNA_string_set: IMPORT_SCENE_OT_makehuman_mhx.directory not found.
RNA_string_set: IMPORT_SCENE_OT_makehuman_mhx.filepath not found.
RNA_string_get_alloc: IMPORT_SCENE_OT_makehuman_mhx.filepath not found.
error: not a mhx file

What am I doing wrong?

You're propably missing the actual file path and file name (see attached picture for more info).

That's it, worked like a charm.

I thought I had to select the file using this file browsing thing, didn't eve notice there was something on the side. Must be a blender thing. Now if I could only knew how to use this...
