Pivot point problem

[Serge Hamad]

Hi,

Select your set in the Scene Preview window then click on “Recenter Pivot” in the set menu.

Thanks for the reply…the advice got me much closer…BUT it still has a small wobble

Thoughts?

sometimes I have to tweak it a bit by hand. Also your fan might not be perfectly symmetric.

good luck…pivot points tweak me out!!

Looks like the fan is not placed exactly 90 degrees perpendicular to the ground.

Hi Guys,

Rick I had a look at your ai file. Your objects are not perfectly aligned so here is what you should do:
-First change your big circle to 323pt X 323 pt. It’s now 321 X 323.6
-Select your layer1 in the layer palette and choose release to layers (Top right arrow), select the new layers and drag them out of layer1.
-Import in Invigorator using the “Import by layer” function.
-In the Set-Up window select all your objects and assign them to set (0)
-Select now the center of your fan (Filled circle) and assign it to set1 to make it the pivot point.
-Select all other objects, assign them to set1 and click OK.
-In the Scene Preview window select st1 and recenter the pivot.
Now animate and everything should be smooth.

If you have questions let me know.

Salut.

This question is for Mr. John Dickinson.

When you have a 3 bladed fan like in this case, and using the 3D tracking method in AE, how do you anchor the controller to the fan so that the z-axis is exactly in the center of the round part of the fan?

As you know, thinking in terms of the fan in a square, the geometrical center would not be in the exact center of the fan because of the triangular shape.

Your help will be appreciated.

Hi,

I think Jon is still in Japan so I answer for him this time. The blades are not important at all in this example. The little filled circle at the center is your pivot point in this case. So as long as you have it as the first object in a set, Invigorator will create a pivot point right in its center. Read my answer above to get a step by step.
Now if you attach your set to a 3D null you will see that it’s automaticaly centered.

Hi Serge,

Thank you for the reply.
I forgot to mention that I’m on a PC.
I will try as you explained and let you know.

Hi again, Serge.

As I import the fan, the blades and the center are separate. In the Invigorator setup window, I can move the round shape to the center, but when I select the 3 blades together, I can’t move that to the center to line up with the round object’s center.

As I mentioned in my original post, the blades are bounded in a square but the actual center is not the center of the square boundary due to the triangular shape of the 3 blades together.

This is the part that I need clarification on. It could be something so minor, but at the moment, I am not finding an answer.

Thanks again.
