On this dialog you can change all the sector properties. When a selection of multiple sectors is made, some fields may appear grayed or empty in case they are different for some of the selected elements. Setting a value in grayed or empty field will apply this to the entire selection.

Properties

You can manually set the Ceiling height and Floor height at the top of this window. On the right are the flats (textures) that are on the floor and ceiling. Left-click on the box to browse for a flat using the Image Browser. If you know the flat name, you can also type the name directly into the text field below the flat box.

In the Effects area you can set a special effect for the sector and set the Brightness level to use.

Below that you can enter a tag number to identify the sector. This number can then be used by Linedef actions or scripts to perform actions on the sector.

Custom

This tab allows you to edit the custom fields on the sector. Only available in UDMF format. See Custom Fields Editor for more information.
