Hello, it’s a simple question: what changes can I make with the post-process button? Can I change the brightness of the objects, the color or the bump or somewhat else? It is not clear to me how I can use this button!
The post-processing applies a few filters to the baked lightmaps in order to improve their quality, and it is always performed automatically at the end of baking. So, running post-processing manually is needed only when you change these filters settings after the lightmaps have been baked. Currently the only configurable post-processing settings are: Enable filters (which effectively enables/disables post-processing) and the Flood dark limit.
