> ⚠️ Note that you must select a folder or a color correction layer to use masks. Otherwise, the masks are inactive.



> ℹ️ Multiple masks can be combined, e.g. an Exposure layer with two masks to it. The blending mode parameter to the first mask (the one on the left) is not considered and is always grayed out.

> ⚠️ Note that all masks are created with **Blending** mode set to **Add**. If there is only one mask child, the blending mode has no effect.

> ⚠️ When seeing masks in preview (i.e. the **Show preview when selected** option is enabled), the name of the layer/folder that contains the mask(s) is in bold in the layers tree.
> ⚠️ 
> ⚠️  Note that the preview cannot be saved.

> ⚠️ When a mask is added to a layer, the **Show masks' preview** option is available in the layer's Parameters tab. This options shows a preview of the masks when selected.





> ✅ Each item in the list has a color icon. The color corresponds to the one saved in the respective render element.
