Mod PTRLib

PTRLib, CraftStudio Importer and Rendering Library

PTRLib is a technical Minecraft mod library for Java Edition 1.12.2 with Forge. Rather than adding blocks, items, or new gameplay systems by itself, it provides the tools required to import CraftStudio assets and display custom models inside Minecraft.

Its main role is supporting content mods that rely on these visual resources, including Decocraft and Camera Obscura. PTRLib works in client and server environments, making it useful for modded Minecraft server setups where custom decorations and models must load correctly. At BoxToPlay, we recommend it whenever a compatible modpack lists PTRLib as a dependency.
