RenderChunk rebuildChunk Hooks

A small(ish) coremod for 1.12.2 to inject hooks into RenderChunk#rebuildChunk to allow Modders to add their own custom chunk rendering logic and other chunk rendering related modifications. Made by Cadiboo

Support

We currently support any combination of the below on the same Forge version

Name	Version	Forge Version	Minecraft Version
Forge	14.23.5.2795	1.12.2 - 14.23.5.2795	1.12.2
BetterFoliage	MC1.12-2.2.0	1.12.2 - 14.23.5.2795	1.12.2
Optifine	HD_U_E3	1.12.2 - 14.23.5.2795	1.12.2
Forge	14.23.5.2768	1.12.2 - 14.23.5.2768	1.12.2
BetterFoliage	MC1.12-2.2.0	1.12.2 - 14.23.5.2768	1.12.2

Note: The mod should work all Forge 1.12.2 versions (actually all 1.12.x versions if you remove the in-code version restrictions) but due to the amount of work required to test the mod on all of them, we only officially support the above versions.

Compatibility

I've just added compatibility with Optifine HD_U_E3! If another core-mod tries to tamper with RenderChunk#rebuildChunk, it is possible that the game will crash. Report it to me and them, and I'll try and fix it myself or work with them to solve the problem!

It is up to the authors of mods who use these hooks to make sure they don't break anything!

Use Forge's Render Pipeline where possible!

Why Coremod?

I submitted a PR to forge that didn't get accepted and with the 1.13 update imminent I decided to push out something that worked for 1.12.2. I will be trying to work with other people to get similar hooks (with better performance etc.) into Forge.
