## CloudEffectStyle :: union

Additional mask which dictates where in the world certain ProcessionLayers are drawn. Origin determined by EffectRelativeTo.

#### Union members

`"none"` | No mask.
`"euclidean"` | Only show within a circular radius around origin.
`"manhattan"` | Only show within a square area around origin.
`"euclidean-outside"` | Only show outside a circular radius around origin.
`"manhattan-outside"` | Only show outside a square area around origin.
`"horizontal-stripe"` | Manhattan, but only along y axis. Useful when you want a layer to occlude screen regardless of width.
`"texture"` | Only show area covered by the 'effect_mask' texture.
`"texture-outside"` | Show area covered by the 'effect_mask' texture and fill the rest of the screen.
