d3dbsp to radiant

[ORDI]

hello all

im here because im working for a new project and i would like to decompile all the cod2 maps (toujane,dawnville...).
i followed this topic curefully to know how to decompile.. Until now, i solved to decompile some of my old maps and see them from radiant, however, there is a problem that i cant fix;
it is about terrains patches, they are like it would say in small pieces, they aren't anymore tied together:

my map decompiled:


my map original:


i tried to find solutions from radiant or in watching .map file but i did not find anything.. i know some have already been able to decompile it completely anyway
maybe do you know a command or something to tie them back ?

i learned a lot of thing from the .map file and i tried to compare original and decompiled version;

in the decompiled version, there are only 4 lines in a mesh:


in the original version, there are a lot of lines in a mesh:


so it might be tempting to copy and paste in a mesh only depending of the material, instead of having a lot of meshes.. but how to know if its the good mesh (it would take 10 years for the big maps)

so maybe someone here got an idea ?

i hope you will understand me,
