When I setup a project in substance and add my normal map it gives me these weird shading issues: (not sure why the lines are happening they didn't appear the first time I imported to substance) You can see this in blender as well but it goes away once the normal map is added It also appears on the top lip of the head…
Hi! Regarding the issue you describe: is the normal maps y-direction consistent between applications? As far I know Blender uses OpenGL normal maps, Painter projects can be configured to use either OpenGL or DirectX. When using DirectX normal maps in Blender, y-channel could be flipped in the shader. Another thing to pay…
