Wind Graphics vs Actual Wind

[Jeremie Dexter]

I have a windmill with two rotors at about 150 height attached to a large gear. This setup goes down to a second large gear to increase speed and that second large gear is currently is attached only to a quern. The windmill has activated the quern in the past.

I'm in winter and the snow is blowing and the wind sound is pretty strong yet the rotors don't turn. I broke the connection of a rotor to the first large gear just to see if it would turn without being connected. Nothing.

My question is, why would there be a wind graphic/sound but no wind? Is this a bug? Has anyone else experienced this?

the large gears have a fair bit of resistance and using multiples of them to increase speed comes at a high cost of torque.  Have you tried just connecting directly to the quern?  I find that often works better unless you have a full 4 windmill rotors.

The short answer is I don't think it's a bug, just kind of tricky mechanics.

Thanks for the response but it's not that.  Here's a quick recap of the situation:

1)The current setup has resulted in the quern grinding in the past, fast and slow.

2)I broke the connection from one rotor to the first large gear and it still didn't spin (just 3-4 axles attached).

3)The rotor has 5 sets of sails attached, so max sail.

3)at about 150 height standing near the rotor, the wind was visibly and audibly blowing, and hard.

Yeah, I can't speak to the apparent wind versus functional power in a windmill.  To me they've usually seemed correlated, but you could have a bug or something from a mod.

And yeah, directly hooking up the rotor to the quern should be enough power to make it move, even if not as fast as you can get from the large gear work stuff.  ....unless of course the wind just happened to be DEAD at that time.

So yeah, I don't know what is going on with your setup. ...unless it was just bad luck when testing the direct connection or mod related.  But yes, could be a bug.

could you post a screenshot? I want to make sure you don't have any non-deterministic branches
