Unity’s senior technical artist Cyril Jover shared the video of the new tool, which will prove useful for photogrammetry enthusiasts. Basically, it uses some clever algorithms to remove all the unnecessary lighting information from the scan and make it more usable for environment design.
In the CG industry, photogrammetry is becoming more and more popular. Being able to use a regular camera as a powerful 3D scanner opens an appealing way of creating realistic 3D assets. However, raw textures generated using this technique contain a lot of lighting information that should be removed. The Unity De-Lighting Tool has been developed to solve this complex problem.

In addition to the original lit textures, the tool requires the following data (provided in texture maps):
- Ambient occlusion map
- Normal map
- Bent Normal map
These texture maps can be baked in Knald, xNormal, Substance Designer or any other baking tool. Once lighting is removed, the texture can be used as an Albedo map in a standard PBR material. The resulting asset can be correctly shaded.
The tool is still early in the development, but you can get it over at GitHub and have a try.
