Thank you Berg !
But I have a problem : I know that the compression type I have to use for the base and mp directories is the zip one, but there are too many encrypting options in 7zip, I don't know which to use. I tried for some, but warzone crashed, saying that it couldn't find the data files. The original base.wz file takes 59Mb, and the maximum i can obtain for it after recompression is around 40Mb
Yes, my model has too many triangles, I will reduce their number in my future models
Another question : can I generate the png image for the model and where do I have to put it ? It must be in accordance with the pie format I think.
Ok for the spaces in names, I will pay attention
