When your level is finished or ready to test, it can be
exported using the
Level Properties panel.
In the Scene sidebar, expand the NXTools - Properties panel.
Locate the Level Properties box.

The
Level Properties panel contains various properties about the current level:
Scene Prefix
Each level has an
internal identifier known as its
prefix. This should be a shorthand identifier that can uniquely identify the level.
For example:Try to select a unique
prefix that will not be shared by other modded levels.
Scene Title
The
Scene Title is the level's friendly name. This is shown when changing levels, in the level select, etc.
Scene Author
The
Scene Author is
your name! This declares the author of the level and is currently unused.
Thumbnail
Declares the
thumbnail image to use in the OpenSpy lobby and level select.
This image should offer a quick overview of your level, or focus on a notable landmark in the level. Choose something
easily recognizable that gives the player information at a glance.
Loading Image
Each level has a
loading image shown when loading into the level. Some users may see this longer than others, depending on their specs.
This should also give an
overview of the level, and ideally contain the level's name in some fashion.
