This is a topic I have seen many junior artists m. Thing is that once the HP mesh is baked only the baked normals are displayed and used in the substance viewport (and iray ren. Many filters and materials adapt to the geometry of a 3D mesh by looking at these baked textures. This means you have to change Painter's project settings to be OpenGL so other OpenGL apps can correctly display the normal map. Solution One: So to export a specific channel you need to go to "Texture Set Settings" and add the channel you want with the plus button, if you already have it, move on to hitting export. Try adjusting only blue channel with Levels for example and see if it makes difference. The Paint tool is the default tool of Substance 3D Painter to apply colors and material properties on a 3D mesh. Seams are visible after baking a normal texture. Also the artifacts are kind of located where edges would be added if model was triangulated so my guess it that substance tesselated the model during import, so it’s a bit different of the one you uploaded to Sketchfab (which has quads). In Maya the meshes look fine, face and vertex normals all seem to be behaving correctly, but when I export as either . Whilst ther. Seam visible on every face. Normally never happen because vertex normals are recomputed if the mesh doesn't have them. 2. Choose Edit menu Transform Reset Transform. 1.
