To understand this tutorial, you need to know how to insert ExGFX files.
::: Within the Level Editor of Lunar Magic (and also on the OW) >>> This controls Layer 3 Bypass.
Here, you can change the Layer 3 graphics that are loaded by the level. This initially changes Status Bar as well. You can also use ExGFX for this, just make sure they are in the 2bpp format.
The important thing to do here is to "Check" the option "Enable bypass of standard layer 3 tilemap for this level."
Everything else under this box is important when making your layer 3.
The box that says "GFX Tilemap File" is where your Layer 3 data is going to be saved and inserted as ExGFX.
Think of a screen as like this:
This chart can represent SMW's 512x512 background format. That means these four "save" buttons represent your background editing area.
This represents the 512x256 area.
This represents the 256x256 area.
There are three settings:
512x512 >>> This will be inserted as an "8kb" sized ExGFX file, effectively taking up the space of 2 ExGFX files.
512x256 >>> This will be inserted as a "4kb" sized ExGFX file, effectively taking up the space of 1 ExGFX files
256x256 >>> This will be inserted as a "2kb" sized ExGFX file, taking up half the space a regular ExGFX file would.
This goes without saying but, DO NOT edit these files with YY-CHR, or replace them. You will either corrupt or lose your tilemap data.
Next is actually making your Layer 3.
Press this: , and go to the OW menu. Click on the [File] drop down menu and navigate to "Layer 3 Level" and click "Load Layer 3 of a Level".
Here you will be able to use tiles from your specifications in the level to make your own Layer 3 tile map. After you're done, save it. Remember to save it as an unused ExGFX file to be inserted with the rom later. I am choosing ExGFXE00 for my selections, but I don't know if that makes a difference.
Afterwards, just go back to in the Level Editor of Lunar Magic and set the "GFX Tilemap File" to your saved ExGFX file.
Disclaimer
I have not used Layer 3 on the OW yet, mostly due to reason that I have yet to have a reason to use it. This should help anybody with questions either way.
