I believe that the playstation 3D was never perfect to edit because there was no use for that.
And sadly I am not good on 3D drawing/programs either.
Maybe using one of those converters on those pages brings you more luck.
Ah well after all the playstation never really HAD a Z Axis so I can see what you mean.
I tried lots of these converters. I will try a different approach and look into ingame data where the models are rigged, make a dump of the memory and look for the TMD Structure.
TMDTool can assemble Ascii TXT files with TMD Structure to TMD files. maybe I can try that.
But thanks, I appreciate your help^^
