Codewalker ymap convertion for SP

[777PROJEKT]

Hey modding amigos!

I would like to creat some Oil Rigs or others maps with code walker, and convert the maps for SP,
but i tryed the tuto on this site, but i can't convert it nothing appear

We need to re-texture/path every single prop in dlc ?
is there an easy way to do it ? I speak french in case a french speaker can help me.

Many thanks everybody and have fun
