Using Zmodeler 1.06 for GTA Vice city ( Nothing else works )

[Bifoutre]

Hello,

I use the dinosaur Zmodeler 1.06 as it is the only version that sucessfully worked for me for modyfying .dff models for GTA Vice City.
Every other options just does messed up results for some reasons.
But I struggle to select some faces of the models that are not the main chassis of a car ( Bumper, bonnet ect.. ) Sometimes it works but it seems random and I do not know how I suceeded.
Thing is Zmodeler1 is so old that none video tutorials exists for it, as Youtube came out later and everyone made videos about Zmodeler2 instead of the 1rst !
Only documentation I ever found is this :

https://www.etspe.ca/zmt/v1/tex.html

https://www3.uji.es/~martiv/tutorials/b ... 0elements.

But it does not cover up everything, only basic info for direction. Other tutorials do exists in GTAforums but all illustration pictures vanished so we can't have visual indication, only text...

Dear Oleg, do you remember how this ancestor works ? Thanks !
