Function Viewport.shadowAtlasSize
The shadow atlas' resolution (used for omni and spot lights). The value will be rounded up to the nearest power of 2. Note: If this is set to 0, shadows won't be visible. Since user-created viewports default to a value of 0, this value must be set above 0 manually.
