I was wondering if a weathervane physic simulation was possible (i.e. a weathervane that is pushed by a wind). I can create something that looks a bit like it (thanks to Chris) but that is not entirely satisfying as the settings are pretty complicated, the hinge object needs to be tilted (?), the wind needs to be carefully placed, etc... (by the way, I've tried the wind Tube falloff option, instead of the Sphere option, isn't the wind Tube option supposed to create a wind effect within the tube area only? Doesn't seem to be the case...)

Result so far:

  • $\begingroup$ For the Tube option, yes it is supposed to do that. The question is how you have set up the falloff... in my Blender it works. $\endgroup$ Mar 21 at 7:41
  • $\begingroup$ If you've made it worked with the tube option (and no hinge tilt?) could you please share your file? $\endgroup$

  • $\begingroup$ I'm sorry, if I had a solution I would write an answer... I usually don't work with hinge constraints. I use the falloff settings mostly when working with particles, and from them I could only say the Tube falloff works. The thing is, with particles being blown around it is easy to see, I'm not even sure how it looks with a rigid body spinning on its axis. $\endgroup$ Mar 21 at 7:55
  • $\begingroup$ Yes I'm not sure that it works as well with cloth or rigid body $\endgroup$

  • $\begingroup$ If you want it to blow wind only in a limited tubular area, you have to set a Radial > Max Distance to ensure wind is not blowing outside of the tube with the set radius. I thought you want it to blow on one end of the cube for example. The problem is, the cube only starts spinning as soon as the hinge object is within the tube max distance. $\endgroup$ Mar 21 at 8:04
