As you may have noticed, the user
pedropp222 already posted a static wind turbine. Then, I was immediately motivated to import one as a vehicle, and animate it.
I know this is made as a vehicle, but it's meant to be a static model. You can spawn it just like you spawn static models, but it will be removed after you quit the game...
The 3D model is a free model I just found here:
linkIf you open the script file(or ALT+E), you have two variables you can change:
var hub_speed = 1.0;
var head_speed = 0.01;
Feel free to play with those
