PIVOT orientation

hello,

 

i am not sure if what i am having it is a technical issue or if i am doing something wrong but, i am attempting to rotate and object and i notice that the pivot is oriented in a weird way, so i go ahead and fix it, rotating in and placing it where i need, after i fix the pivot rotate the object a "gear in this case" and key frame it, when i play the animation the pivot is all f ed up again and the gear is rotating all over the place, i have notice that every time i click on another object or just click anywhere else the pivot just lose all my editing, it's kinda frustrating, i am trying to have a simple animation with 3 gear rotating but i can;t if they are not rotating in the right way. i have attached the file if you would like to have a look, is the 3 gear on the pillar 

thanks

Hi!

 

You checked settings to make sure you baked "Position and Orientation"?

 

For further help, please add a screencast.

Hi!

Thanks, now i understand the problem.

 

Try this:

 

1. Delete the key at frame 15 with Rotate [0 0 0]

2. Orient Pivot to the center of the wheel.

3. Modify Freeze Transformations.

Now you can use Rotate X to rotate the wheel.

Hi!

Sorry, it's not what you can see in my screenshot.

Again, orient to the center:

(Don't use Freeze Transformations afterwards)

Hi!

Your problem is rotation values + rotation order + how rotation works, but i will not go into detail here.

Again you did not do what i showed in my screenshot.

Don't move the pivot to front center vertex, just orient it to front center vertex.

This will work!!!

 

1. Delete the keyframe at frame 15

2. Select object and enable Rotate tool

3. Execute script

manipPivot -o -89.675576 -73.752606 -0.000463207 ;
BakeCustomPivot;

=> now you can use RotateX for rotation
