I am making grass (field of wheat) and I added wind. My windmill is affected by the wind but wheat is not! How can I fix this?

I am sharing my wind and particle system options. I want my all objects to be affected by the wind.

These are screenshots of the particle system settings:

screenshots 2

screenshots 3

And this is my wind options:

What am I doing wrong?

  • $\begingroup$ Check if the wind force field and particle system objects (emitter and instances) are located on one 3D layer. It's likely they already are on one layer with the windmill $\endgroup$ – Mr Zak Oct 29 '17 at 10:01
  • $\begingroup$ Thay are on the same layer look at this picture: image.prntscr.com/image/z0qtE2AlRIyX8MOiNQ5rhw.png $\endgroup$ – özcan özaltın Oct 29 '17 at 20:31
  • $\begingroup$ In hair dynamics turn down stiffness. $\endgroup$ – sambler Oct 31 '17 at 1:11
  • $\begingroup$ Possibly there's a checkoff in the "field weights" settings that enables forces? $\endgroup$ – Dr. Farquaad Oct 31 '17 at 1:21
  • $\begingroup$ i did turn down but just spring long time. not wind effect. $\endgroup$ – özcan özaltın Oct 31 '17 at 1:34

Try changing the Initial Orientation under Rotation from "Object Y" to "Velocity/Hair".

Settings for Rotation

Keep your other numbers as they are; those in this image are for my particle system.

This will probably mean that your wheat will not stand up right. To fix that, select "Rotation" in the Render section. Then, if the wheat is still not standing up, try rotating your actual "Bugray" object by 90 degrees along first the X, then Y then Z axes.

enter image description here

Each time come back to your main layer with the particle system on it to check the effect, then if the wheat is still not upright, undo the previous rotation and try a different axis.

Eventually the wheat should stand up, and because it's rotation is following the hair, it should be affected by wind and other force fields.
