[TEC/wip] How texture works when importing 3d model in SH4? Historical 4 blades prop

[kapitan_zur_see]

Hi

Some fella already started a thread about 4 blades props vs 3 blades but i feared people might confused it with that well known wrong turn prop fix since it was called "4 blades prop fix".
Plus, I have a technical question regarding 3d model importing with pack3d (some people modding SH3 with it might help me!)

Historically acurrate U.S subs propellers were made of 4 blades instead of 3 blades as seen in the game.
Done some modelling, here's the result ingame:





As you can see, the 4 blades prop 3d shape of the model works perfectly, import via pack3d worked regarding this.
However, texture is completely messy/doesn't appears right at all! It's as if UVW mapping had been override or has gone awry in the process.
I've always had this problem while using Pack3d. Is there something special to do in 3dsmax regarding uvw mapping or else before importing back, aside flipping normals?? Or is it a pack3d issue with SH4 since it was made for SH3??

Thanks for help
