Question

3D ring larger than taller...

Hi,

It's driving me crazy.

I've got that 3D ring from Blender imported in AE latest version.

As I'm not able to know my 3D object dimensions, I've made this expression for the position values :

------------------------------

Z= 0 ;

c = thisLayer ;

W = c.sourceRectAtTime().width ;

H = c.sourceRectAtTime().height ;


[Math.round(W),Math.round(H),Z]

 

-------------------------------------------

 

The position values displayed are :

81 920, 7 256, 0

 

How is it possible my ring being larger than taller ? Am I a math genius inventing a new kind of circle ?

Of course, my 3D rings seems to be right in front of my camera, no tilt on any of the camera views (front, right, left)...

How is it possible ?

My brain thanks you with helping it.

GP

Probably just another of the gigazillion bugs in the 3D renderer. Anything more than that would require an explanation of what you are actually trying to do. Surely if it's just a ring the math would be simple enough to dial in some values with expressions...

Hi Mylenium,

 

Thanks for your answer.

I'm tying to animate some kind of "Saturn thing". I mean a globe with a ring.

All these guys would be animated following a path on a ground. A null object mastering all the stuff.

I want to be able to change the ring size, so I need my ring bottom to always be stuck to the bottom of my null object (witch will move on the floor..).

If I'm able to know my ring dimensions, it's quite easy to do. It's perfectly working with other object I tested, but not with my ring...

Using width value rather than height value seems to work out well, the width one may be correct...
