animation bug
« on: January 22, 2020, 11:25:24 am »
I'm animating a complicated hinged set of pliers. I have the movement done so they close on the bone correctly. I then animate everything to rotate/turn everything over to look at the underside. This is where the problem is. The "translation" movements of the innitial "closing" gets screwed up when I rotate everything 180 degrees. All the other innital rotations translate just fine.

Hi Wayne,

It's a bit hard to tell what is going on in the scene.

Would it be possible to share it with us?

Hi Wayne,

I sent you a fixed version of the scene.

The culprit was that the 'Axis Orientation' for the Translation animations was set to 'Global'. Changing this to 'Original Local' (read: respecting the origin of the parts/model) fixes the issue of the components shifting.
When combining translation and rotation animations, it is usually best to use the 'Original Local' Axis Orientation for all animations.

Thanks DriesV! Sorry for the dramma and false alarm. Never ran into this before.
