WebFeb 1, 2024 · The problem with this approach is that you end up generating a lot of geometry for faces that are always hidden (which in most cases is what happens to most of the faces). I ended up using a greedy meshing algorithm which merges multiple faces in order to decrease the total triangle count, which speeds up the rendering process. Web"Greedy meshing" algorithms are one approach, which is explained on the Roblox blog or in this post with a nice animation. Basically you start in one corner, and expand in one …
