X-Plane .obj vs Wavefront .obj

[ncc1701e]

Are X-Plane 10 .obj format and the Wavefront .obj the same thing? I am asking because in Blender 2.69 with Xplane2Blender 3.20, I see an option for X-Plane .obj export in File->Export, but I don't see anything related to X-Plane in the File->Import menu but I do see a Wavefront .obj option there. So I was wondering if its the same format and how would I import an X-Plane object into Blender 2.69.

 

Thanks

they are not the same.  I am not sure if the blender scripts for version 2.69 contain xplane .OBJ import scripts, I do not think so.   The original "xplane2blender' scripts for blender 2.49 DO have an import option for xplane OBJ; however, it is a bit limited in that it does not support a lot of "modern" OBJ commands.

 

The method to import an OBJ into blender is to:

 

1.)  Use Blender 2.49.  Menu item under import exists

2.)  IF the import fails (which it probably will), remove all lines in the OBJ text file that begin with 'ATTR'.  This usually requires a custom script or 'GREP" search/replace to remove those lines as there might be a lot and hand removing could be  tedious but doable.

3.)  Retry the import

4.)  If successful, save and then open with Blender 2.69

 

CAVEATS:  Make sure the 3D cursor is at the (0, 0, 0) position before the import.  IF the import fails after cleaning out all lines with "ATTR" in them, then clean out the lines beginning with "ANIM".  If that fails, clean out every line that doesn't begin with the word "TRIS".  Only do this 'cleanout' on the part of the OBJ at the bottom of the file...after the sections with lines beginning with "IDX".  those IDX lines and all above must stay intact.   The blender 2.49 import script will choke on some "ATTR" and "ANIM" commands so that is what you want to clear out.

I see. Thanks for the detailed advice. Greatly appreciate it. It seems there's is still a bit more ways to go before the new blender/python versions get a complete import functionality into the xplane2blender script.
