Blender export

[bruno.chansou]

For the facerig to work, you need to load the file pydrivers.py from the utils/mhx folder, preferably before import.

Yes I placed the file pydrivers.py to /blender.app/Contents/MacOS/.blender/scripts/ . Is this the right way to do?

Edit:
Today I load the new mhximport.py . The FK/IK choice don't exist. (?)
Thanks.

The pydrivers must be loaded into a text window in Blender before importing, cf. http://wiki.blender.org/index.php/Dev:S ... /PyDrivers or http://blenderclan.tuxfamily.org/html/m ... nt/?id=113

In the current revision (rev. 555) you can select Arm IK and Leg IK with two buttons to the right, at load time. Currently it is not possible to do FK/IK switch dynamically by moving bones in the panel, since this apparently did not work. It can still be done manually, by setting keys for the Copy Rotation constraints on the upper and lower arms/legs.

I don't know why but the two buttons don't exist. For me the interface mhximport.py rev 555 is exactly the same that rev 495. I download the file twice for be sure.

thanks for this, I'm going to try with this.


Edit: Facerig works fine with the right workflow. Thanks

Edit: Now the two buttons are here and work correct. Thanks very much.

Hi Thomas,
I tried today the latest version of mhximport after reading the blog.
I'm not a guru. I just try to understand. For the fk ik switch works is still better to click once anywhere in the ipo curve editor. It is as if there was a bug in blender and need to update the ipo curve by clicking in the window ipocurve.

EDIT: This is not elegant, strange, but it works: Just after moving a bone of the Ik Fk switch, just click once anywhere in ipo curve editor or action editor or NLA editor and the switch works.

I explained your problem on a French forum. That is the answer (it's in French but with google translate I think you can understand)

EDIT:
And the problem of the new skin shader that you mention in the blog, it's just properly adjust the scale in panel sss. The scale is 1 mm in BU. If you choose 1BU = 1m then scale is 0.001. If you choose (as in mhximport) 10BU = 1m then scale = 0.01

Since changes, i`ve got problems wiyh import to blender mhx meshes. Pydrivers.py loaded (i think) and get error trying import:

It is possible of low RAM memory (512 MB)? Or i missing something

There are two separate problems.

1. pydrivers.py must be loaded into a text window, but it should not be executed. It should just sit there.

2. It seems like you are trying to import an old mhx file. There has been a slight change since your file was exported, but I have evidently forgotten to update the version number. More precisely, the "driver" statement now takes two arguments. Export a new mhx file from MH and everything should be fine.

[ThomasL]

The import script has now been modified to work with old as well as new mhx files. The offending argument was not used and is now ignored.

Thank you for reply. I`ll check this and answer if it helps

EDIT: Yep, it works perfectly Mea culpa for using old mesh

Hi Thomas,
You work quickly and well. I could test today the mhx exporter for blender 2.5 (build Blender 2.5 (64 bit) [26,829] of GraphicAll) with the new nightly build of Makehuman for Mac OSX. The script works correctly. This is not really usable (blender 2.5 isn't stable enough), but promising to soon.
