# Cloud Motion Effect
The Cloud Motion effect adds a cloud motion to certain parts of the image. You can customize the direction through the effect settings and limit the effect to certain parts of the image via the opacity mask.
If your clouds are very close to other objects, it might help to place the clouds on a separate image layer. When drawing the opacity mask, make sure to add some distance around the clouds and keep distance to other objects to prevent unwanted image distortions.
# Effect Settings
