ui-mob
by nali1
With ui-mob, Forge players on 1.12.2 get extra mob and world generation content, with model and animation data loaded through a C component.
What it does
ui-mob adds cute entities that generate in the world, so a 1.12.2 world gains creatures it would not have in vanilla. The mod has an entity worldgen feature and is built around the mob category, with world generation as a secondary area.
Part of the mod is a C library that is fetched and compiled with a command, then used to move model data and shaders into memory. The author says this loading path is faster and keeps data in a sorted form, and the release file stays small. High quality models and animations use the GPU heavily during rendering, so that cost falls on the client.
ui-mob is released for Forge only, with a single file for 1.12.2: version 1.1.2, published 2026-01-06. Installation covers the server and each player's game. The code is under the MIT License and is open source.

Use cases
Mob-focused 1.12.2 packs

GPU-capable clients
Because high quality model and animation rendering draws heavily on the GPU, the mod suits players whose machines can handle that load.
Who it’s for: Forge players on Minecraft 1.12.2 who want extra mobs and are willing to compile a small C component. Server owners can add it too, since the mod runs on client and server.

What the author says
Model/Animation is high quality and need to use gpu much to render. With C code make it faster to load data to memory and data already sort so you will get small size of file.
