Easier way to rotate objects?
show user profile  Nolan
Hi again,

Sorry for almost spamming this thread but I have one more question. I am trying to animate an object spinning. I want to easily change the speed of how it spins. The way I have been doing it is placing 4 key frames and having the object rotate 90 degrees each key frame. I have spent the last hour or so googling for tutorials but I cant find one for something so simple. There has to be a command or tool that will work better but I cant for the life of me find it.

Thanks again!
Nolan

Answer: Graph editor

Tutorial: http://www.expertrating.com/courseware/3DCourse/3D-Animation-1.asp

In a nut shell: The graph editor displays a vertical and a horizontal value. On the vertical you have a selected value (rotation for example) on the horizontal you have time (frames). If you set a key on frame 0 with a rotation value of 0 and another key on frame 100 with a rotation value of 360 then over the course of 100 frames your object will turn 360 degrees.

Can I put a key on lets say 900 and have it turn that many times?

Do I still use the normal time bar and key frames and just rotate the object 900 degrees?

You can. You really should go through that full tutorial. If you follow along you'll understand how it works.

Easy fix: right click on the rotation button and a box with XYZ values will open. Go to the frame you want, type in 900 on the axis you want and key it.

If you don't do some basic tutorials you will have more and more questions and will end up wasting your time.

Well I did read through the tutorial. And It gave a description of how the dope sheet worked and everything with moving keys around but when I rotate the object using the way you said it will pretty much ignore the command. Perhaps I am just doing something wrong?

Ctrl + Alt + Right click (hold) > Drag the time line.
Move the key (you only need one, not 4)

Dave's method (sweet tip about the easy timeline scale!) would also work as a start point, with a "Loop" out-of-range controller from the curve editor, if you need that object to spin multiple times through your animation.

Thank you so much!!!! I finally found out what my problem was. It was setting the Default In/Out Tangents for new keys. Now with these new methods my animation will look much smoother. Thanks again to everyone for their amazing help.
