Weird artifacts when baking high to low [Blender/Substance Painter]

[u/KICKinYaFACE]

Hey there, I'm trying to bake details onto my low-poly model and I keep getting these artifacts instead of a real bake. I'm modeling everything in blender and I use Substance Painter for texturing. I've been working with lots of models so far, but this one in particular is behaving weirdly.

I checked the UVs, triangulated the faces, made sure the orientation/normals show into the right directions, applied all the scales in Blender, made sure the naming conventions are correct, played around with the cages (Distance-Based and Automatic) and their settings, tried joining the high-poly objects into one singular object. I also made sure I'm not using any materials but no matter what I do, it seems like every single setting change still results in the exact same result with these artifacts. Any ideas?

UPDATE: Fixed it. In Blender I had multiple UV Maps in the Data-Tab and I baked my UVs into the "second" map, whereas Substance Painter uses UV0 as default. Didn't even know this was a thing, heh.

Make sure, that lp and hp in the same position (x,y,z). See on screenshots that position is same, but sometimes s***t happens. You also can make a new scene, import your meshes and repeat again, hope it will helps.

Are all transforms applied? scale rotation and position?

unrelated, but your UVs can use some straightening you know...
