How would I go about easily animating wheels? Any tutorials anywhere?
It is just a little math knowledge. The magic formula is 2Pir.
- In Side view add Circle
- In frame 1 insert (āiā) key LocRot
- Move to frame e.g. 25
- Move your circle e.g. 2 Blender Units
- In frame 25 insert LocRot key
- In IPO editor find find Rot key of appropriate axe the circle should rottate. Probbaly it will be RotY
- Press Tab so you can edit point of this curve and choose your second point of curve
- Press N to get into Transform Propperties of the Curve
- The Ymax value should equal to 2Pir (Pi is 3,14, r is radius of your circle). If your wheel rotates backwards the number should be - minus
That is it. You may need to set Rot IPO curve as linear extrapolaited.
There are also other ways for example using stride bone - http://de.wikibooks.org/wiki/Blender_Dokumentation:_Stride_Path
