Hi Everyone,

I have been using Blender for 2 months, so I am beginner. (I am using Blender 2.63a)

I would like to make animation with a lot of gear wheels so I need to use Coinstraints. Copy Rotation mode seems to be very simple and usefull but I have got problem.

If I set `Influence` on 1.000 everything is ok, but if I dicrease this parameter my wheels don`t go properly... I made short animation for you. In this example I applied all scales, all rotations. Wheel with Influence 1.000 work properly, but wheels with Influence 0.5 and 0.2 have problem (about 5 sec of movie).

Could you help me , please?

I am not really sure but maybe you can try something like this

you have cogs A B C D

A copy rotation to B 1.0
B copy rotation to C 0.5
C copy rotation to D 0.5

Maybe it will work like that

Check also if you have any limit rotation applied.
If yes remove it.

Its a little late but maybe this is the answer to your problem.
