The normal map will disappear from the viewport, but that is expected. In order to override/paint the normal map it is important to set this setting to replace instead. 1 - Changing the Texture Set blending modeīy default a Texture Set is created with the normal mixing setting set to combine. This behavior can be changed via the Texture Set settings. The default setup of a project in Substance 3D Painter doesn't allow that, as it computes the normal channel and the baked normal separately. In some situations, it can be useful to be able to paint over the baked normal map in order to hide details (or even fix baking issues). Therefore when using an OpenGL (Y+) normal map, it is required to click on the little arrow to open the color space menu and then change the color space of the bitmap.

This setting can be used to specify the Normal map format since by default a DirectX (Y-) normal map is expected (it is not affected by the project setting). When loading a normal map into the slot of a material (tool properties or fill layer), it is possible to change the default color space. To learn about them see the Blending modes page.

Normal maps have their own blending modes in the layer stack: Load a Normal resource in the Normal slot of the Material section of the current painting tool.įrom there, painting with a normal map is very similar to Height Map Painting, with the added precision of a baked normal.Enable the normal channel in the current painting tool.Add a normal channel in the current current Texture Set (if not already present).This page regroups different way to manage normal map painting. Painting details can be done by painting directly Normal map data directly on the mesh.
