It’s a Texture Coordinate issue. Be sure all TexCoor nodes are exactly the same number. You might have one TexCoor node set to 1.0,1.0 connected to a Texture Sample, but then another TexCoor node set to 2.0,2.0 connected to a different Texture Sample.

After setting all TexCoor nodes to exact same number, for example 0.50, 0.50, the black splotching disappears
