This is what I used to make the preview image for SCP:CF.
Includes: Background 1 (First layer) BG2 BG3 Darken Character Logo Icon Etc. Read the Description for this file for how to use it.
Version 2 now includes: Character 2 layer (Duo support basically)
Version 2 of the Thumbnail creator template I made
If you have a mod you want to use, Here is some instructions (and Examples)
For FNF Mods
The "Character" Layer is used for character sprites
The "Character 2" layer is mainly used for songs, or characters that are duos. Like Engineer and
Robo Engineer in Frontier Justice.
Icon is used for the health grid icons (use the icon that your character uses)
Logo is for mod logos
BG2-3 are optional
Background is for your character's background (like the character's stage)
For example. Scout's background is his first stage (twofort)
And Colin uses, BG 1, BG 2, and BG 3, due to how many layers his stage has. And Scout (Above) has only one stage image for his stage (twofort)
And the Darken Layer can change colors depending on how you want it. and you can change the layer transparency, and that also depends on how you want it.
Song name and character name layers are optional.
Most of these thumbnails are also inspired by "KosterZero" on youtube.
Metal Gear Rising, or any other game doesn't require as much as you think.
For any other game, you need a background, or you can mesh the Character into the Background
(Like I did for SCP: Containment Failure 2.2.2)
If the character isn't in the background, you will need a .png file for that character. Kinda like Senator Armstrong.
Then paste that said character into the character layer (pasting the character into the background layer-
-will make that said layer transparent.)
Then paste said logo (the game logo / title) in the logo layer, boom you're done.

The most recent update to this adds Duo support (Kinda like Engineer and Robo Engineer (Seen i nthe Preview))
No seriously here is an example.
As you can see, the Robot Engineer is there, unlike KosterZero's version.
