About this asset
Pixel perfect occlusion system that will significantly improve the performance of your scenes, without almost any overhead.
Using time of your computer, precompute/bake your scenes to gain a significant performance boost. The occlusion culling algorithm will find all visible meshes from each point on your scene, using the color-coding algorithm. Then it will save them efficiently and load only when needed.
Now with Runtime Baking support!
Heavily occluded scenes like a two-story house with the interior on all floors gained us up to 240% in frame rate!. From 30fps to 72fps on Quest 2.
Open world scenes with flat chunked terrain, gained us 10-25%. From 47fps to 60fps on low-end mobile.

Technical details
Single occlusion bundle size should be calculated as (uncompressed):
{Average visible percent of meshes} * {Meshes count} * {Occlusion Areas} * 4 * 4 = {Size in bytes}
Example:
40% * 600 * 400 * 4 * 4 = 2,304,000 bytes = 2Mb ~= (compressed) 700kb
The uncompressed number can be treated as a memory footprint in the RAM.

Compatibility
| Unity version | Built-in | URP | HDRP |
|---|---|---|---|
| 6000.0.77f1 | Compatible | Compatible | Compatible |
Currently, this package only supports URP and HDRP for the baking process.
Rendering and Culling are independent of the rendering pipeline.
All Examples might require a rebake to work correctly, or runtime baking component.
The lowest tested Unity version is 2020.3.X
