Summary
With Tiled Baking, the process of denoising a lightmap is broken down into smaller ‘tiles’ with each tile being denoised one at a time. The tiles are then combined into the full lightmap to produce the final result. The data involved in baking and denoising large lightmaps (e.g., 4k lightmap resolutions) may not fit within the available.
Use Case / Intended Outcome
For devices that are capable of running the Unity Editor, the Tiled Baking and OpenImage Denoising technique helps reduce the memory requirements of the Lightmapper. This technique breaks down the baking and denoising process into manageable chunks that can fit in the available memory at any time. As a result, you will be able to utilize Lightmapper to denoise any lightmap size with min spec devices of the Lightmapper.
