Assuming you are with iClone v7.1.
RL made it easy to spin props in latest version. There is no need to create a key for every 90 degrees of rotation anymore.
The rotation range has expanded to 20K degrees (from -10K to 10K). So with just 2 keys your prop could revolve 55.5 times (20000\360).
Assign the rotation of -10K to the first key
Assign the rotation of 10K to last key.
If it is too slow for the duration of the clip, you can replicate those keys.
Let say you have 1800 frames and want to rotate the fan ~100 times. The scheme is as following:
key 1 - Rotate Z -10000
key 900 - Rotate Z 10000
key 901 - Rotate Z -10000
key 1800 - Rotate Z 10000
Just make sure that keys 900 and 901 have LINEAR Transition Curve.
Once done, you may also collect the clip and Add to Perform. But I have learned that for some reason the first 15 to 20 frames of the resulted perform clip are "frozen".
I need to cut them before I can extend the perform clip.
Finally you may use Physics with Constrain to rotate the fan.UPDATE: lol, I just realized it was iClone 6 forum... so scratch that... or upgrade
OR you may still use collect clip / Add to Perform routine in iClone6. And then extend the resulted clip any number of times without the need to copy paste keys.
