Blender IK and FK problem

[spinalcord]

Hey,

Some question if i change FK to IK with mhx2 setup, why the human mesh don't move with bones?

Could you provide a bit more information about what you did and what doesn't work.

Version of MH and Blender
Operating system
How did you export?
How did you import?
Which bone did you move? FK/IK?

hello wolgade,

Version of MH: r1777 (cd5ba31c6a7) nightly build.

Version of Blender: 2.7.4

Operating system: Windows 8.1

Export: Mhx2

Import:

Overide exported data [X]
HumanType: Base
Offset[X]
Face Shaps [X]
Face Drivers [X]
Add Rig[X]
Rig Type Mhx
Custom Shaps [X]
Rotation Limits [X]

Which bone did you move: foot.ik.r

[wolgade]

Just to get this right: After import you switched the legs to IK, moved foot.ik.r, the rig moves, but rhe mesh doesn't deform? This would be strange. Your import settings look ok to me.

exactly, here is my blendfile with vanilla import but i can't find nothing specific.

???! The test with your file worked for me. I don't understand your problem. Perhaps these information help you for the usage of the rig: https://thomasmakehuman.wordpress.com/m ... e-mhx-rig/

Works exactly as it should.

One thing I noticed: The foot.ik.r bone was in a position, where it physically can't be without ripping the leg out of the socket. You can't use IK to make legs longer.

After amount of hours with testing around, i finally found this issue. You need turn on auto python script in Blender to get it work, otherwise you can only use the basic rotation. FK and IK works fine now.

Yes, it took me a long time to figure it out too the first time. This problem was once mentioned in the docs, more precisely in http://www.makehuman.org/doc/node/exporting_a_character_to_blender_with_mhx.html, which you reach from the link in the mhx importer http://makehuman.org/doc/node/makehuman_blender.html. However, at some point somebody else took over documentation and this info was probably lost in the process.
