>>1885032>>1884806 here, i'm not very keen on uploading stuff, but i could happily post the process here.:first you need to find a breast from a nude model that could fill the gap, in this case since the breasts that we want to fill are small, we need to use a model with small breasts or similar, i'm going to use tda rin.
in pmxeditor select the mesh that has her breasts and erase everything else, because the tda body was created from the darkstalker body, the breast mesh is in two separate materials, for commodity i combine them.
now you need to erase the vertex of the remaining material so it can be easily to manipulate, and later save it as a separate pmx file, after that move that file to the folder the model you want to add that part and import it to the model.
from there erase more vertex to your hearts content to fit it in the hole, you can also resize or rotate it and move it near the gap, use the subscreen to see your progress. in this case i only imported one breast so once you done fixing the position, select the mesh and mirror it.
now we should combine the vertex, but first we need to give this white mesh the texture of the body and then edit some stuff with the uv mapping plugin (this part is important, doing it bad/not doing it at all will make the model look bad when you combine the vertex)
select the breast areola mesh from the uv map and move it where the gap is; for commodity, i move the areola material near the body material in the list so i can see it better.
once you did that you start combining the vertex, for better visibility put the camera inside the model and combine the vertex of the gap with the nearest vertex of the areola, careful with not combining other vertex. do this on the other side as well
i'll continue on next post, since i'm at almost the post limit
