Rotation of multiple gears for clockwork stuff?

I never used blueprints before, so noobian alert! I watched a youtube tutorial for rotating meshes, which was already too complex for me, and I can’t go any further. Currently I have this:

I managed to rotate my gear. But I can’t rotate multiple gears at different speeds by simply copy-pasting the thing. I plug in different meshes, create variables for each, but it only rotates one gear. I plugged 3 gear meshes into the same “target” input, just to get at least some rotation, and I’m currently stuck with that. Help!

I want to achieve something like this:

Gears needs to rotate:

  1. Each at different speed.
  2. In different directions.
    That should be super easy to do, but I can’t even figure that out. =(
  3. Ultimately I want to rotate the whole pack of gears and casings as if they are a single element, like in the video example. That I predict would be painful. In my imagination I would just select all rotating elements, press “Group”, then apply rotation to this group. But again, I’m total noob. I’ll appreciate anything, a link for a tutorial, maybe planetary rotation scheme, anything similar.

You could add a rotating component to your gear blueprint… create several different gear blueprints and use different settings for each one… ie. one in the forward direction and then one in reverse.

Stupid tutorial got me doing things in the level blueprint. I gotta create individual blueprints, got something working here already, thanks. But I still have no idea what I’m doing tho.
But problems 1 and 2 are solved. For problem 3 I need to research parent and child relationship maybe?

Still haven’t found the solution. How do I rotate a bunch of rotating objects as a single block?

I’d set each of your gear an index. Odd is for clockwise rotation, even for counter. And basically you need to know this). So every gear must have at least index and gear ratio)
