You can see an interesting feature comparison to texture baking in Marmoset Toolbag, one of Substance 3D Painter’s key competitors for this kind of work, in the comments to this YouTube video. Other new usability improvements include automatic highlighting of hard edges on the model without corresponding UV seams – which can result in artefacts in the baked textures – in both the 2D and 3D views. Users can also start or cancel baking directly from the viewport, and can continue to interact with the model in the viewport during baking: for example, to identify issues with and cancel the bake early. The new system improves viewport visualisation of the process, with both the high-poly and the cage mesh shown in the viewport, and any part of the source mesh that falls outside the cage displayed in red. The main change in Substance Painter 8.3 is the new baking mode, which replaces the old baking window for baking geometry-based texture maps like normals, ambient occlusion and curvature from geometry. New baking mode lets you bake textures directly from the Substance 3D Painter viewport

The update introduces a new baking mode with better viewport visualisation of the model being baked, replacing the old baking window, and adds support for importing and exporting USD files. Adobe has released Substance 3D Painter 8.3, the latest version of the 3D texture painting software.
