From 69fc20610947610b7829f3bfad82e23ed705b764 Mon Sep 17 00:00:00 2001 From: x2048 Date: Tue, 31 Jan 2023 17:30:59 +0100 Subject: 8x block meshes (#13133) Reduce the number of drawcalls by generating a mesh per 8 blocks (2x2x2). Only blocks with even coordinates (lowest bit set to 0) will get a mesh. Note: This also removes the old 'loops' algorithm for building the draw list, because it produces visual artifacts and cannot be made compatible with the approach of having a mesh for every 8th block without hurting performance.
