Replace OIDN denoiser in Lightmapper with a JNLM denoiser compute shader. by DarioSamo · Pull Request #81659 · godotengine/godot
github.com
Original proposal: godotengine/godot-proposals#7640 Background "Nonlinearly Weighted First-order Regression for Denoising Monte Carlo Renderings" (https://benedikt-bitterli.me/nfor/nfor.pdf) mentio...

TL;DR:

Before:

An image showcasing the old de-noiser

After:

An image showcasing the new de-noiser

These images are 2 weeks old and there have been some changes to it, as well as a slider to adjust de-noising. Notice how much more pronounced the ambient occlusion is, and how much better the overall shading is. It’s also faster than the older implementation.

On the scene I used for testing this out, the overall rendering time went down from 3 minutes to just over 1 minute in an RTX 3090 Ti with an 8K lightmap.

Bonus: This PR shaves off a massive chunk of the codebase (about 10% apparently.) Expect faster build times and a smaller engine size in 4.2!

    As in automated testing. I don’t see CI run nor any code hinting at automated testing.
