Frustrator
by PT400C
Frustrator hides and shows regions of a Forge 1.7.10 world, so that only the areas a player can see are rendered at a given time.
What it does
Areas are defined with two tools. The main area tool selects a rendering area that can be hidden or shown dynamically. The trigger area tool creates additional zones that act on a matching main area, either showing it or hiding it. The aim is to reduce the rendering work the game does during play, with improved performance as the stated goal.
The project started from the idea of using real view frustums to decide visibility. The author notes that working with frustums is efficient but awkward to build on, which is where the mod's name comes from. Earlier approaches to switching zones between hidden and shown states were described as inefficient, and very large zones could lag heavily or disconnect a server. Frustrator is written to be more scalable for those cases.
The mod is server required and client optional: the server must run it, while players may add it to the client. It is released under the Apache License 2.0 and is open source. It needs UniMixins, which must be installed alongside it. Forge files exist for 1.7.10 only, and the latest file, 1.1.3, was published on 2026-05-27.

Frustrator is a Minecraft Forge 1.7.10 mod inspired by old 90s 3D video games which employed trigger areas to hide/show certain parts of the game level.
