Hi, I am trying to create an animation of a planet rotating. I have checked all tools and all I can find in (modifiers, constraints, etc) is the ability to move a sphere 180 degrees. How do you get a complete revolution??

Spin the planets Yaw 180 degrees... Maybe set the animation for 5 seconds at 15fps... Move the timeline marker to the 5 second point. Select the planet and open the Properties window. Move the Yaw parameter 180 degrees from its current location. This should add a ekyframe at 5 seconds in the timeline. If you press the run button the planet should now spin.. That help? If not let me know. Clint

You can apply the spin modifier to an object to get it to spin.

Hi Clint, No luck. Still can only rotate it 180 degrees. I tried the spin modifier, but it spins too fast, I think the lowest setting you can use is 1 rotation/sec. Any other ideas?? I tried setting 2 key frames( 1 halfway (4 sec) and one at the end (8 sec) but it just reverses the rotation at the 4 sec mark. Keithw, is there a way to sec the spin/sec to .25 rotations/sec??

Nemisis, I'm not sure what you mean? You can set the number of rotations per second. If you set the rotatations per second to .25 and the length of the animation to 4 seconds your planet will make one complete rotation during the 4 second animation. If the cycles per second are a positive number the planet will rotate clockwise. a negative number will rotate it counterclockwise Keith

Hi Keith, Carrara will not allow me to set anything but a whole number. 1 is as low as I can go.

Hi Keith & Clint, I tried to set the spin again to .25/sec and this time it worked fine, sorry guys. Thanks alot

Also what you can do (for future reference) Is have the planet go 180 at the first keyframe and then at the middle keyframe set it to 0 then at the last set it to -180. That'll do it. Although Spin works too. :) Hoborg
