is anyone ever going to fix this?

Bug #947

[duststorm]

If Joel adds a rig section to the user contributed assets, we could upload the OpenSim rig that was latest in MakeHuman nightly there.
It's not completely perfect and has its problems, but it's the best there currently is.

If Joel adds a rig section to the user contributed assets,

I've been holding off this until I was able to figure out how the mhskel export blender plugin works so I can write at least basic pointers on how to create assets for that repo. However, since I have so far not been able to import even the simplest armature as a skeleton in MH without getting a crash, I've got stuck at that point.

The rig looks like this (I named the bone "root") :

The sum total of the generated mhskel file (after having edited the plane null values) :

Code: Select all

{
    "bones": {
        "Root": {
            "head": "Root____head",
            "parent": null,
            "reference": null,
            "rotation_plane": "Root____plane",
            "tail": "Root____tail"
        }
    },
    "copyright": "(c) Makehuman.org 2015",
    "description": "Armature skeleton",
    "joints": {
        "Root____head": [
            19150,
            19151,
            19152,
            19153,
            19154,
            19155,
            19156,
            19157
        ],
        "Root____tail": null
    },
    "license": "GNU Affero General Public License 3",
    "name": "Armature",
    "planes": {
        "Root____plane": [
            0,
            0,
            0
        ]
    },
    "version": 102,
    "weights_file": "simple_weights.mhw"
}

The latest crash I get is this:

Code: Select all

Traceback (most recent call last):

    p1 = skel.getJointPosition(j1, human)[:3] * skel.scale
  File "./shared/skeleton.py", line 429, in getJointPosition
    raise RuntimeError("Cannot get joint position, no reference vertices or joint name specified.")

... which is not the same as when having failed to edit the null values for planes.

But I guess I could open a rig repo anyway, with fields for mhskel, weights and thumbnail.

This needs to be edited by hand, there is no GUI for it.

You need to replace the three 0's with three names of joints, defined under the section "joints" of your skeleton. Extra joints can be declared (by specifying a name and a set of verts) to add new reference points.
MH will draw a plane between those three points, and then rotate the roll of the bone so that its local y axis is parallel with the normal of the plane.

There's no immediate plans to build a GUI for this, so has to be done by hand using a text editor.
