There might be version compatibility issue ? or perhaps unity should update blend to fbx converter.

convertedASCIfbx.txt
originalBlend.txt

The original blend file is the Blender 2.7 default cube.
fbx file is converted from a .blend file by the unity engine.
I keep trying to find a c# ASCI.fbx to BIN.fbx converter.

I am not versed in 3dmodel file formats. Had to delete assembly info files... wasn't working under Unity. This is how I execute your scripts

var reader = new UkooLabs.FbxSharpie.FbxAsciiReader(new FileStream(PostMan.NewFbxFilePath, System.IO.FileMode.Open)); var doc = reader.Read(); UkooLabs.FbxSharpie.FbxIO.WriteBinary(doc, Path.GetDirectoryName(PostMan.NewFbxFilePath) +Path.GetFileNameWithoutExtension(PostMan.NewFbxFilePath) + @"BIN.fbx" );

And this error pops up. Are these .fbx files generated by Unity have some unexpected data on them?
