Your load screen must be 1024x1024 pixels in size.
Change materialType to 2D and surfaceType to <none>.
Setup the map to use the load screen
In the list where you selected "material", choose "level" and make the new name the same as your map name. Then fill it out according to the picture.
Save the file as "mp_mapname.gdt" in your "source_data" folder.
Setting up your map's Zone file
Now run the converter from the applications tab in Launcher.
Open your [levelname].csv in Zone Source and add "material,loadscreen_yourmapname" to the right side.
Build the fast file and see if you have your load screen.
