Fixing Missing Custom Title Screens and Mod Menu Buttons
If you installed a mod expecting to see its signature moving panorama or special title screen buttons, only to be greeted by a different menu or a startup warning, Cumulus is usually the piece managing how that screen appears.
Resolving Missing Dependency Warnings
Mods like the Aether series rely on Cumulus to run their custom menus instead of handling title screen changes alone. If your game stops on a mod loader error screen before reaching the main menu:
1. Read the error message to confirm whether a mod is asking for Cumulus.
2. Place Cumulus into your client's mods folder alongside the mod that requested it.
3. Relaunch Minecraft so the background menu tools can load properly.
When Another Mod's Menu Takes Priority
If the game launches fine without errors, yet you still do not see the custom panorama or special buttons for your newly added mod, another menu layout is likely selected instead.
1. Open Options from the current title screen.
2. Find the setting that lets you choose which menu screen you want to see.
3. Switch the active layout to the mod whose custom background and buttons you are looking for.
4. Return to the main menu to load that mod's moving panorama and custom button layout.
