Forgematica
Forgematica requires the MaFgLib library to function.
Forgematica is an unofficial port of the Litematica mod for the (Neo)Forge platform. It's a modern client-side mod for working with schematics in Minecraft.
This project (also known as Litematica-Forge) is a client-side mod for creating and working with schematics in Minecraft, offering numerous additional features particularly useful in creative mode. These include: schematic pasting, area cloning, object moving, space filling, and element deletion.
Originally, Litematica was created as an alternative to Schematica for players who preferred not to install Forge on the client side, hence development was focused on Liteloader.
Compatibility
Shaders
In Minecraft versions 1.21.3 and newer, Forgematica's rendering doesn't work properly with shaders (even with Iris). If you need to use schematic display features in Forgematica, it's recommended to disable shaders.
In older Minecraft versions, rendering works better with shaders, especially with Iris, but the results depend on the specific shader pack. Some shader packs significantly disrupt the display, while others work relatively stable. Optifine generally creates more issues - it's practically impossible to use shaders together with Forgematica when using Optifine. It's recommended to use Sodium (and Iris) instead of Optifine.
Valkyrien Skies
The mod will never be compatible with Valkyrien Skies, but if a compatibility request is provided for this mod, it will be accepted. (The reason for incompatibility is that Valkyrien Skies is written in Kotlin) Additional information about Valkyrien Skies compatibility can be found at: #69
