It is impossible to set these parameters independently for each Baked Map in Substance Painter before the baking process, therefore after you bake them they should be exported as 16-bit PNG files using the standard “Mesh Maps” preset.Get Adobe Substance 3D Painter as part of the Substance 3D Collection plan.

World Space Normal Map and ID Map are advised to be the same resolution as the final texture map, 16-bit Color. It does not make much difference if it is baked in 16-bit or 8-bit Color so it is rather up to your preference.Īmbient Occlusion Map, Curvature Map, and Thickness Map are advised to be the same resolution as the final texture map, which is 16-bit Greyscale. This map is just a gradient, has no influence on resolution, and is used only by Substance Painter generators. The Position Map is advised to be half of the final texture map resolution. Especially if the model contains many small details. The quality of this map is extremely important both for generators in Substance Painter and in-game. It depends on the performance of your particular hardware. This is the only map that might be baked not just at the same resolution as the final texture map but even 2 times bigger. Color gradients on this map are very important for model lighting so making it less than 16-bit might lead to lighting quality degradation. The Normal Map is advised to be 16-bit Color. There are a few hints that will help you to decrease their size without influencing their quality.

Baked Maps (also called Mesh Maps) could unreasonably make the project file much bigger than it might be.
