Hello,

I am using the ASSIMP command line tool to export from various file formats (.dae, .3ds, .ase, .obj) to .obj. After importing into my object viewer the shading seems to be inverted on the y/z axis. I can recreate this issue with all the described file formats except for .obj. If i export from max to obj (no matter which setting) import to assimp and export to obj again, the issue is gone. I had no look with .dae, .3ds, .ase file formats. After exporting those from assimp to o.obj i have the described problem.

I tried converting the .obj to utf8 and displayed them in webgl (using threejs) with the same effect.

  • @ ulfjorensen : I am sorry. Is there a way to delete this entry from here? I made this double post because i recognized that the forum allows a better representation of the problem than the bug reporter. I really don't want to spam :-/

     
  • No problem. To my knowledge there is no way to delete anything here... we sometimes have *real* spam here, but there's no way to admin it and the sourceforge team never responses to anything. We'll just let it rest, maybe it's a real bug even.
