Current questions and answers regarding the map editor.

How can I add the object categories (effects and others) mentioned in post #1765, as shown in the screenshot?

FullEditor.h5u is renamed to FullEditor.pak and placed in the data folder...

For completeness, you need the mod from here

MapFiltres
Adds many objects to the editor, which previously had to be obtained through a complicated process (mainly, many effects). To install, copy MapFiltres.xml to the Editor folder in your game folder.
