I was going to put this problem in the Rigging section, but then realised it was the first Biped I had tried to skin in Max 09. Then I loaded Max 08 and tried the same thing, to find the problem wasn’t present in that version. So I’m thinking it’s another Max 09 bug.

I imported an Obj figure from “MakeHuman” and created a Biped for it, went in to Figure Mode and started adjusting the bones to fit the skin mesh in the usual way.
One of the adjustments was to rotate the neck forward a bit so the head bone was aligned to the character’s head (Pic 1).
When I exit figure mode the neck snaps back the the vertical position (Pic 2.

As I said you don’t get this in Max08, and I tried again in a fresh scene in Max 09 in case I had done something wrong, but got the same result.
Can someone else please try this and confirm if it’s just me or a genuine 09 bug.
Or does anyone know of this and has a fix or workaround.

Max 9 needs to be fully patched for Biped functionality, which SP are you running?

Read his post again Shea - he said “Max 09” not “Max 9” (something I wish people wouldn’t do as it’s very confusing).

OIC said the blind man,..  should not be a problem though, that envelope can be adjusted to deform that area just fine, but I understand the concern.

OK, check this I just tried to duplicate the problem & it worked fine.  I suspect that the imported rig is the problem.  Try creating a new BIP and see it you can dup the ‘bug’… workaround is to recreate the BIP in Max 2009, you can probably transfer the FIG file, but if it is simple I would just re-adjust it from scratch.

I’ve kind of fixed it by putting the neck back to vertical in figure mode and moving it into position (see pic1).

That’s a good point, I wasn’t thinking ahead. But it may be a problem for less human characters with horizontal necks (Pic 2 Sample character scene).

The only thing I imported was the mesh for the skin. The Biped was created in Max. I get the same if I start a new scene and new biped.

This is Max 2009 32 bit SP1 on XP Pro SP2, these are the steps to duplicate the problem.

1. Choose File - Reset. To start a fresh scene.
2. Create - Systems - Biped, drag out a biped in the viewport.
3. Go to the Motion Panel and select Figure mode.
4. In the Left viewport select the biped’s neck bone.
5. Rotate the neck.
6. Click Figure Mode off.
The neck snaps back to it’s original orientation.

Do you mean it happens in Max 9 as well?
It doesn’t happen in Max 2008.
Shea, what version are you running?

My Bad I rotated the head,..  Funny if you hit ‘clear all animation’ in the keyframing tools group the thing rotates outside of figure mode..  of course by then I had also enabled separate tracks, Neck - and swaped the sub ani controller - or wait the controller did not stick, but the rotated neck DID!  Even with some down range keyframes.  Maybe I stumbled on a workaround....  same specs as you BTW - running Max 8 - 2009.

I feel a Defect Report coming.
Thanks for trying this.

Confirmed here too. Tried in all versions (from 7 through 2009) and only 2009 exhibits this behaviour. Time for a bug report?

Already sent it.

I’ll send one too - the more they get the more likely they’ll look at it (and hopefully fix it).
