Biped different behavior in max and unity

Hi all,

I'm working with avatars in Unity and I found a wired behavior. When I open the avatar .max file in 3D studio Max 2011, I can move the bones separately, I mean, the Bip (root bone) rotates the whole avatar, then the Spine ( son of the Bip ) moves only the Upper body of the avatar, then the Spine1 only a bit upper and so on.

The problem starts when I import the same .max file into Unity. For the Bip and the Spine1 the behavior is the same as is in Max but then, when i rotate the Spine, the whole avatar rotates but keeps fixed the Bip, so the mesh gets deformed in a bad way.

Please see the attached images to better understand what I mean. Sorry, I'm a programmer, not an artist so maybe the problem is easily fixable. the first image is the avatar in unity without any rotation, the secon one, rotating the Spine and the third one, in Max, rotating the Spine ( this one is the good behavior should happen )



thanks in advance.

 

There are Biped settings called, I think, Triangle Pelvis and Triangle Neck.

These define how the bones are parented to each other inside of Max and can give unforseen results when exported to the game. Try enabling (or disabling - toggle it to whatever it's not) the pelvis one try re-exporting?

 

Thanks Farfarer, seems to work fine now. I'm going to try the code now. thanks again

 

OH MAN...... I wish I had known about this ages ago!! Thanks for the tip!

 

This helped me too, it fixed the legs but I'ms till having problems with the spine, gah! Thanks though, useful stuff

 

upper leg 's parent is hip in unity3d but in 3dsmax biped it is spine not Pelvis
