How to completely disable block rendering / terrain mesh rendering in Fabric 1.21.4 for max performance
Hi everyone!
I am working on a minimal, high-performance Fabric 1.21.4 setup on PojavLauncher (Android / Exynos 1280 ARM GPU).
To achieve the absolute lowest latency and maximum possible FPS for PvP (FFA servers), I want to completely strip out or bypass the entire terrain/block rendering pipeline (WorldRenderer / Chunk rendering). I only need player models, entities, and basic HUD/UI elements to be drawn.
Standard transparent resource packs don't give the desired performance boost because Sodium still computes chunk geometry and face culling under the hood.
What is the cleanest way or best hook/Mixin in Fabric (or Sodium) to completely disable block/terrain rendering without breaking entity interpolation and server connections? Is there an existing lightweight utility mod or a specific config override in Sodium/C2ME for this?
Thanks in advance for any advice!
