I just upgraded from Blender 2.69 to 2.71. I loaded my previous save file and found, to my dismay, that my pose no longer displayed properly. I'm using Makehuman version 1.0.0. It appears that FK still functions as expected, but IK does not. IK hand and foot targets do not affect arm and leg placement. The root bone appeared to work.

Any ideas how I can (preferably) revive my save files with the new version? Alternatively, is there a way I can export the pose from 2.69, save in the neutral position, then re-import the pose in 2.71? I don't see any export options for poses in 2.69.

  • $\begingroup$ I use an MHX rig. The FK does work, but IK does not. I'm interested far more in IK, as I find it much easier to use. :) I am unsure what you mean by drivers being blocked. If you mean my OS is blocking the operation of some part of Blender, I think that is unlikely. $\endgroup$ Jul 1, 2014 at 13:58
  • $\begingroup$ EDIT: I believe you mean the "MHX drivers", which I can see in the properties panel. I don't see anything that appears different in 2.69. And I do have IK enabled in the FK/IK switch. $\endgroup$ Jul 1, 2014 at 14:03
  • $\begingroup$ As a Stack Exchange noob, I wish I could edit comments more than 5 minutes out. --- @gandalf3 - I think you are right. Blender itself was blocking the driver. I just noticed a little message on the status bar. I said "reload trusted", and the pose is working. This may also have to do with the fact that I had "auto-run python scripts" disabled. I think this is resolved. I'm not sure if I'm supposed to retype this info in an answer and credit you? $\endgroup$ Jul 1, 2014 at 14:16

If you had auto run python scripts enabled in your preferences for 2.69 and you haven't enabled it or copied your user prefs in the new version, then it might be because some python drivers are being blocked.

If this is the case, there should be a message in the info header (at the top of the window by default):

You can either press Reload trusted each time you open the .blend, or make sure auto run python scripts is enabled in User preferences > File > Auto Execution:
