Wise, I agree ...

... and will focus on finishing my own project ...

Thank you very much everyone for taking time to help me with your skill ! :yeah: I just don't understand why it was good before I exported the model ? .... :06:

Pass of file OBJ through 3d-programm , i.e. circuit of processes: Import from S3D -- Export in 3d-programm -- Import from 3d-programm -- Export in S3D changes in the OBJ file record about textural coordinates.

Yes, we are. It is worth it? Probably not. Why we are into it? Personally because a subsim friend asked for our help, and because I love everything that is related with WWII, (naval) simulations, 3D modelling and Silent Hunter games :subsim: :D

Roger that.
Thank you for your unvaluable help. I wish you many pleasant hours with your own projects. Looking forward to them :up: :salute:

Good question, but I have no plausible answer for that, only some undemonstrated guesses that are not worth being mentioned here. The one thing I can say for sure, is that it looked okay (some problems are partly visible even in the original unit), but from the beginning it was not good. There is no way that S3d can corrupt a model that way once exported :yep:

More or less what I was going to say. Vertex order gets rearranged when passing from a program to another one, so faces that might have been hidden below other faces in the original unit, might have become apparent after passing the model through Wings3D. If so, we should assume that the original author was lucky that all the problems affecting the model didn't show up at first, unless he made something for hiding them that I don't know. But I repeat, one thing is sure: the model was flawed from the beginning...

Gap, kendras!

All airplane models converted from early versions of Combat Flight Simulator to SH3 have these kind of flaws. Well, these models were among the first ones to enter SH3 and were done when modding was not as easy as to today (there was no S3Ditor, just some cloning programme, the rest was hex-ing).
