Forgematica

Forgematica requires MaFgLib.

Litematica unofficial (Neo)Forge port. A modern client-side schematic mod for Minecraft.

Forgematica (or Litematica-Forge) is a client-side schematic mod for Minecraft, with also lots of extra functionality especially for creative mode (such as schematic pasting, area cloning, moving, filling, deletion).

Litematica (Original mod) was started as an alternative for Schematica, for players who don’t want to have Forge installed on their client, and that’s why it was developed for Liteloader.

Compatibility

Shaders

Forgematica’s rendering doesn’t currently work properly with shaders (even with Iris) in 1.21.3+. So when you need to use Forgematica (schematic rendering), disable shaders.

In older MC versions the rendering works better with shaders, at least with Iris, but also depending on the shader pack. Some shader packs break the rendering pretty badly, but some used to work pretty nicely. Optifine in general is/was a lot more problematic, pretty much you can’t use shaders at all with Optifine if you use Forgematica. The general recommendation is to use Sodium (and Iris) instead of Optifine.

Valkyrien Skies (1.20.1 only)

When Forgematica is installed alongside Embeddium/Sodium and Valkyrie Skies, entering the world causes a crash. This issue stems from a compatibility mixin between Valkyrie Skies and Embeddium/Sodium. For details, see #69.

PrettyPipes (1.18.2 only)

Saving PrettyPipes pipelines in schematic and then loading these schematic into the world causes crashes. For details, see #119.
