I know I’m not the only one having this issue and I’ve looked and looked for fixes from others but none of them work.
Quick description. Using wind on a plane with cubes used as hair objects. The cube is at the origin with all transforms set. I’m using 4.1 but have tried in 4.2 also.
No mater what I try when I increase and decrease wind force, the cube rolls in the proper direction but it flips along the world’s z axis. I’ve tried many setting changes with the object itself, with the force and with the particle system.
Is there an issue here or am I missing something critical. I’d like to know so I can stop trying this method if it’s not doable.
Have you set it to use Global Coordinates in the Particle Settings?
I had to rotate the original cube x>90 and then all the faces of the particle cube faces would be the same as the original cube ( you select the bottom of the original cube and it selected all of the instance’s bottom faces instead of a side), but if I tried to apply rotation it flipped all the instanced cubes 90 on x.
That is about all I can say without something to look at and more details with what you are doing, or the Blend File.
Thank you I have tried that. I put all my orignal instances at the grid center and set all modifications. I toggled global in the PS settings and I’m using global overall set in my view.
the solution I found was to set the wind force at .7, set up my objects to be upright at that wind setting and then when animating to never let the wind force go below .7.
Another way of saying is
1.after setting your original object that is replacing your hair particle at grid center and saving location, rotation and scale
2. set your wind factor slowly until after the object flips in your particle system
3. Adjust the position of your original object until the particle system objects are where they should start.
4. Treat that as starting wind force and don’t go below it.
I’m not sure what to do if you want them to go the other direction and you have to go below that. It seems to flip at 0.
I wish I knew a better solution.
I don’t know if .7 Is the right setting for everyone.
I also found that using fade in the graph editor helps. I have Graphkit that I like a great deal. Fade in Graphkit reduces the bounce and flip so it looks much better.
