Gimbal lock occurs when linking


#1

Hi I am very new to 3ds max and need some help rigging a character.
I have a character that has a tail. I created bones for it with correct Euler rotation order I intended.
Then whenever I link them to pelvis, one axis aligns to one another, gimbal lock happens.
I’ve recorded this process so please take a look.

Why is this happening? I appreciate any advices.

Not as familiar with biped since I prefer using CAT, but doen’t biped has dedicated tools to help with adding bones like this instead of just linking:

Why YXZ order?


#4

agree…Tail Links…say 10

job done.

Xtras! I didn’t try this one. Thank you for your kind reply.
Your suggestion works perfect. Awesome

Still wondering why the gimbal orientation changes itself when linked.
But I’ll absolutely take your advice and rig my character with xtras this time.
Thank you so much KAAF and Vusta!

I’ve thought maybe the tail won’t yaw in x axis direction much.
That’s why I put X in the middle to prevent gimbal lock. So YXZ.
Maybe it’s a wrong decision?
Please let me know if I am misunderstanding.

Don’t have to be afraid of gimbal lock.
Most probs with that you could have with (imported) mocap and similar animation files.
And you cant avoid that, you don’t know it’s there until you play it. Good start would be to recognize it.

About the order…
Place/orient the (bone) pivot in favor to desired axes, don’t change the order.
If you chose to animate/rig with some system than go with system.

You can check the (local) orientation of bones in bip and CAT
