Visible seam in curvature and mask editor generators, looking for solutions


Hey guys I'm getting these really nasty seams when I use the curvature generator or the mask editor. The seam is barely visible in the curvature mask itself so I am confused why it is so strong once using a generator based on that map. It is less of a problem when the UV seam is on a hard edge, but for some objects like this one it is impossible to unwrap without a UV seam on a curved surface.
Ive tried baking the curvature map out with all sorts of different settings without any success. The sliders sharp/fine/soft/medium etc under the curvature generator can reduce the visibility alittle but does not eliminate the seam.
I figure I can just paint it out, but I would prefer to keep things fully procedural until the last steps rather than having to paint every time I use one of those generators.
