milk_instancer01's Introduction

Milk_Instancer01

Indirect GPU instancing & painting with occlusion culling, frustum culling, and LODs in Unity

This Project is undergoing a large refactor.

This project is built off of elliomans indirect rendering with compute shaders. https://github.com/ellioman/Indirect-Rendering-With-Compute-Shaders

What is different in this version?

gpu bitonic sorting is now no longer reliant on powers of two (thanks to EmmetOT - https://github.com/EmmetOT/BufferSorter)
improved user interface
instances can now be painted into the scene, much like unitys terrain detail system
amplify shader editor examples
wind shader example

Features

BIRP support (included in this repo (occlusion culling not setup yet))
URP support (soon)
HDRP support (https://github.com/Milk-Drinker01/Milk_Instancer_HDRP)
instance density control
paint prefabs on any object
multiple prefab support
per-instance occlusion culling
frustum culling
up to 3 LODs
Amplify Shader Editor examples
ShaderGraph examples
wind shader example (ASE and SG)
Multi-Material Prefab support (for things like trees)
world streaming/detail zones
VR: supports both multi pass and Single Pass Instanced

What am I still working on?

Render Pipeline Consolidation
built in renderer occlusion culling
URP support
more spawning methods, perhaps procedural terrain spawning
