That thing is already stated in the FAQ in the 1st post.
- What to do if model's affected by wind ingame(moving by itself when outdoors)
Some shader parameter sets have "um" parameters, which makes that effect(usually, such parameter sets have "_um" in the name).
You should check all your materials using GIMS material editor, and set parameters like these to zero(0):
- "Global umParams: ScaleH/ScaleV/FreqH/FreqV"
- "Wind: (x64/Xbox1/Ps4): Stiffness Multiplier (ps3/360):SclH/SclV/FrqH/FrqV"
("Wind:SclHV/FrqHV") <==== oh sorry my bad i didn't notice this,Thanks
