Let's see a few different ways of how map files can be opened.

Start by selecting the map editor of a type you want to open, in the tabs above the Editor area.

Open a map by clicking the Open button, which is the second button above the Editor area.

The Open File window will appear: select a file and click Open.

An easier way to open a file is to simply drag it from the Windows File Explorer and drop it into the Editor area.

If the map editor of the type you wish to open is not the currently active type, hover with the dragged file icon above the map type tabs: the active editor will change and you can drop it into the Editor area (not into the tab itself).

When the file icon is dropped into the Editor area, it's opened and can be edited.

To open several maps at one, so that you can open a complete material, you can either select multiple files in the Open Maps window we saw in step 2 of this guide, or simply drag'n'drop the files into the current Editor window.

Either way, the Open Maps window will open, where you can check if the map types for the files being opened.

PixPlant will try to understand the map type from its filename and will automatically select the map's type. For other entries marked "Select..." you'll need to manually select the correct map type.
