forgematica Patch Mod

Forgematica Patch

This mod restores compatibility between Forgematica 0.4.2 and NeoForge 21.1.235.

Without this patch, loading a schematic causes Forgematica to crash with an IllegalAccessError caused by access to the private BufferBuilder.building field.

The patch uses a small Mixin compatibility layer without modifying Forgematica itself.

Requirements

• Minecraft 1.21.1
• NeoForge 21.1.235
• Forgematica 0.4.2
• MaFgLib 0.4.3

Problem

Without this patch, loading a schematic causes Forgematica to crash with:

java.lang.IllegalAccessError:
class fi.dy.masa.litematica.render.schematic.BufferBuilderCache tried to access private field
com.mojang.blaze3d.vertex.BufferBuilder.building

This patch resolves the compatibility issue on NeoForge 21.1.235.

Solution

This patch restores compatibility between Forgematica 0.4.2 and NeoForge 21.1.235.

Notes

This is a compatibility patch only.

It does not add new features or change Forgematica’s functionality.

It does not modify any Forgematica files.

It can be removed at any time without affecting your worlds or schematics.
