# OVER\_Canvas The **OVER\_Canvas** is a core component responsible for setting up the screen canvas UI of your OVER Experience. It allows you to create customized features that interact with the experiences you’ve uploaded to your Land.
To ensure a smooth user experience, only a sub-section of the screen is available for placing custom UI elements. This area corresponds to the bottom of the screen, with its activation button located at the bottom center (Exp. UI). All UI objects must be placed under the **Panel** , inside the mask of the **PanelContainer** . Any UI object placed outside the mask will not be rendered.

Additionally, only **one OVER\_Canvas** can exist in a scene. If you attempt to include more than one, the original **OVER\_Canvas** will automatically be removed to prevent conflicts. All the UI objects must be placed under the *Panel*, inside the mask of the *PanelContainer.*
If a UI object is placed outside the mask, it won't be rendered.
