Blender 2.56a import error

[Tindytim]

I'm using Blender 2.56.0 R34231, and the makehuman build I got from the Arch User Repo, which reports the version as 1.0alpha5-2 (http://aur.archlinux.org/packages.php?ID=8387).

When I attempt to import an MHX file I've exported this is the error I get:

Code: Select all

I'm using Arch Linux x64. Any help would be greatly appreciated!

It looks like you have an old mhx file; older than alpha 5.2 I think. Try download a nightly build from http://download.tuxfamily.org/makehuman/nightly/.

I've got a truly interesting problem. I'm using Blender 2.56a from blender.org, and MH Nightly build 1778 in good old Ubuntu 9.04. After initializing the addon in Blender, but not using the 1778 python scripts, the import loads the Expressions shape keys, but not the LipSync. Is there a hotkey for the LipSync interface that isn't part of the Shape Key interface? If I use the 1778 scripts, I get a whole series of python warnings, and all that gets imported is the .obj portion, and the armature.

btw, my students--mostly female--love the 'Software Barbie' aspect of Makehuman. They truly enjoyed that lab. More on their comments later.

[ThomasL]

This is a combination of two effects. The lipsync tool earlier than 1770 is not aware of the expressions. The mhx importer was changed in 1774 to work with a change in Blender's api. It works with Blender svn but not with 2.56a. Hence you need the updated lipsync tool, but not the updated mhx importer unless you also grab an updated Blender from graphicall.org.

The lipsync tool is implemented as a Blender add-on, but it is not yet distributed with Blender. The file view3d_mhx_lipsync.py must hence first be copied to Blender's addons folder, and the add-on must then be enabled as described in https://sites.google.com/site/makehumandocs/blender-export-and-mhx/copy-addon-to-blender and https://sites.google.com/site/makehumandocs/blender-export-and-mhx/enable-addon.

Is the file space_view3d_mhx_lipsync.py that file? Given how fine-tuned this is, I'm thinking I'll need to know.

[ThomasL]

If the expressions are included in your mhx file (this is controlled in proxy.cfg), they can either be accessed directly as shapekeys, or from the UI panel if you run space_view3d_mhx_lipsync.py. I will write something about it, but not today.

Unfortunately, Blender has just changed how you define add-ons, so this file may not appear in the add-ons list even if it is in the addons directory. However, you can always execute it in the text editor.

I compiled makehuman, created a couple test characters, but alas, Blender has decided to spit out yet another error:

Any help? Same version of blender, I'm going to test out the version released on the site soon.

EDiT: Turns out, the binary from the blender.org site turns up no errors. I'm not sure if it's that I'm using a nightly revision, or if it's the fact that I compiled it with custom CFLAGS.

Your mhx file is outdated. Export it again with an updated build and import it again. However, wait until tomorrow's nightly build because today's is broken.
