CustomSpyglassMagnificationOverlay

This is a mod that allows customization of the overlay when zooming in with a telescope, and it has been open-sourced on GitHub.

You can adjust the style of the overlay when zooming in with a telescope by using the command /csms-config (mode) or by modifying the mode item in the csms-config.json file located in the config directory within the game directory. There are a total of 4 modes:

Mode | Value to Enter in Command or Config File | Explanation
— | — | —
VANILLA | 0 | Vanilla mode.
CUSTOM | 1 | Allows customization of the background through the left.png and right.png files in the assets/csms/gui directory of the mod JAR file.
NO_BACKGROUND | 2 | Does not render a background.
NONE | 3 | Renders nothing but the zoom effect.
