[away3d] Reversed Materials in v3.6

[William Grand]

The Obj parser reverses the materials.  This is a known bug -- does
anyone know how to fix it?

I tried editing Obj.as's function, prepareData(), and I could reverse
the material, but the geometry is backwards.

I changed:

                        _geometryData.uvs.push(new
UV(parseFloat(trunk[1]), parseFloat(trunk[2])));

To:


                        _geometryData.uvs.push(new UV(1-
parseFloat(trunk[1]), parseFloat(trunk[2])));

And I think I need to modify this line, but I'm not sure how:

                        _geometryData.vertices.push(_vertex = new
Vertex(-parseFloat(trunk[1]) * scaling, parseFloat(trunk[2]) *
scaling, -parseFloat(trunk[3]) * scaling));

I believe I am supposed to swap the first two parameters of Vertex,
but the geometry gets screwed up:

                        _geometryData.vertices.push(_vertex = new
Vertex(parseFloat(trunk[2]) * scaling, -parseFloat(trunk[1]) *
scaling, -parseFloat(trunk[3]) * scaling));


Any help appreciated!  Thanks
