I don't know how to fix. What i can do: - bake curvature from mesh (and it picks high definition mesh if its available, ignores the normal map) - bake curvature from normal map (but it doesnt pick the high poly mesh) In attachment you see the 2 curvature maps it creates. You can disable this by going to the normal factor setting on the leaks brush and setting it to zero. Matching by name for occlusion rays. In almost every cases, this is something you want to avoid and Substance 3D Painter won't accept to work with UDIM as long as you have UV island crossing multiple Tiles. 1 Correct answer. I am aware that some artifacts are normal and I'm not striving for perfection here, but I'm not getting any of the beveled edges or further detail after the bake. It sounds like there may be some sort of issue with the mesh geometry. This will let you more easily see issues with the normal facing. This will present itself very similarly to using a totally wrong tangent space, like normal maps baked from 3ds. Here's how you mirror layers when normal symmetry isn't enough-!!Substance Painter Symmetry Tutorial Link:painter】 关于sp的小问题合集，希望大家在学习路上更加的顺畅！ 解决了基础的问题，早点提升吧！Figure 2: The black shadow / outline along the outside of the mesh is horizon occlusion that's suppressing light leaks from backwards facing vectors in the normal map.
