Spin around one point

Hey there,

I´ve a problem spinning the ear of a rabbit.
My animation should be similar to this video:
http://www.youtube.com/watch?v=m10h7nXSZ_g

But because I´m not familiar with programming, the ears leave the body of the rabit when they spin :( I tried to find some solution like "spinning an object around a specific point" but I didn´t find one.

My unsatisfying solution until know looks like this:

Quote:

turnAround = vizact.spin(1,0,0,200,30)

Ear1.addAction(turnAround)
Ear2.addAction(turnAround)

p.s.: Body and ears were all single objects which I positioned in a room

Can someone please help me?

THANKs

path = viz.add(viz.ANIMATION_PATH)
positions = [ [0,0,0], [0.2,0,0], [0.4,0,0], [0.6,0,0]]

for x in range(0,len(positions)):
Ear1.setPosition(positions[x])
cp = viz.add(viz.CONTROL_POINT)
cp.setPosition(positions[x])
path.add(cp,x+1)

path.loop(viz.LOOP)
path.setAutoRotate(viz.ON)

Ear1.link(path)
path.play()

but this is also not what I expected

The issue relates to your sub-object's center point not being where you expect. If you use 3DS Max to create your geomoetry, you'll find this KB article very helpful:

I´m not using Max until know, because I´m not the creator of the 3D Model. But I´ll try. The links seems very helpful. Thank you very much. I let you know if it was successful ;)
