outfit studio, Weight paint and clipping problem

[grandslasher]

hey i have been trying to convert some of the ladybody outfits for my uunp body for personal use.

using outfit studio i shaped the mesh to my body and copied breast butt weights to it.

But theres clipping on hdt movements.

without the breast weights theres no clipping on movement

Is this issue due to the higher poly count of LB outfit compared to uunps low poly breast?

Can anyone provide a solution? thnx in advance..
