In this course, you will learn substance through the painter, UI and navigation, realistic texturing, hand painted texture link or connect texturing and rendering using MBTI. I already have assigned the materials to the object in Blender and i see them in Substance Painter because i see 5 UV Maps also in Substance Painter and i see the nice layed out UV Map on each material So i know that is okay. Basically, the resolution of your texture isn't high enough to accurately represent the gradients needed to compensate for the smoothing. These faces can then have Material definition assigned, which become Texture Sets in the application. Recalculating normals can fail if the mesh is non-manifold and Blender gets confused between the interior and exterior. It has specific parameters which can be edited via the Properties . Just hit export again, check the obj if it got normals correct this time, make a zip, upload it again. I have attached two images. If it says polySurface6 (or whatever name you gave the poly) has no UV coordinate. 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). The detail is baked into the associated mesh normal map. Please help! I'm going to have to resort to painting them in zbrush otherwise which will be a super frustrating experience. If enabled, ray distance computations are based on the normalized space (0 to 1) of the low-poly mesh.
