Hi there.
While this isn't related to any sort of bugs, it may add onto the Mineblox Project.
Minecraft uses a flood fill algorithm in order to simulate lighting, Mineblox uses the standard Roblox lighting engine which is sometimes limiting.

I recommend you check out this topic that I've made about how shaders are made here:
https://devforum.roblox.com/t/how-its-done-making-shaders-part-1/2647970
(it doesn't mention the custom lighting engine, but you can make your own by using raycasts and textures to simulate Minecraft's lighting process)

There is this bug where the fall damage, and arm won't show. Which means I can't mine.

I have not touched the Generation Manager Script but there is 1 Error

1. When the Terrain Loads the Oak Logs don't appear. Only a hole into the Void that I am able to fall into.
2. The Sides of Blocks Such as Leaves and Dirt don't have their side textures. After dying I received this Error.

StarterPlayer.StarterPlayerScripts.Modules.Chunks.Terrain.GenerationManager:486: attempt to index nil with number - Client - GenerationManager:486

(also I am a huge fan of you and the series, keep up the good work :D )

Hey! There is no error for this one but I wanted to know if theres a script that Generates the blocks. I noticed that it doesn't use the blocks from ReplicatedStorage.Items

I tried finding the script that makes these blocks because you could use MeshParts as a Block for the Mesh Items that you want to make.
