that's the hard part
Generally the "reverse way" requires a FULL format analysing.
If it's removing only (not changing) there's a chance to set the concerning vertices to 0.0 0.0 0.0 or set the face indices to f 1 1 1.
But you'd need to identify where the data is in the g1m file.

(Don't have the time to check that.)

that looks complicated
i'll do what i can...
anyway thank you very much for your time. i'll try to reach the hokuto team... best and last option.
