Please help, I follow all the baking rules, but when i baked model in Sabstance Painter i get inverted normal map. I had to flip it in the Blender to get normal shading. What did i do wrong?

switch painter from directX to opengl normal format (or vice-versa) in your project settings - it'll flip it for you

you'll probably need to rebake your mesh normal map but everything else should just update by itself
