gaps between seams when displacement on texture added

hi friends!

i've imported a tight, good quality FBX from clo3d into substance

(and all the mesh fit together tightly here in clo).

also output high quality UVs.

in substance, i'm using a knit fabric from the asset library.

any idea how i can stop these gaps from appearing between the seams?

(i've seen this youtube video already but it didnt work for me: https://www.youtube.com/watch?v=axguS69rFT0&ab_channel=WesMcDermott )

any help apprecaited, still quite new to painter. thanks!
