So that's what UVs are for! I don't necessarily need a bitmap data if there's something easier, that's just all I found in the documentation.
In any case, the screen is no longer black on view (infact it's quite a pretty render of a texture) however the alignments are still off. The second face aligns correctly it seems, but I don't totally understand what to do with the first face to get it to align properly. See screenshots below if interested. Here is my updated code: // In class [Embed(source="C:/pic.jpg")] public var faceBitmap:Class; // In function var texturedShape:Mesh = new Mesh(); var f:Face = new Face( 0:0:0, 100:0:0, 100:100:0, null, new UV(0, 0), new UV(1, 1), new UV(0, 1 ) ); var f2:Face = new Face( 0:100:0, 100:0:0, 100:100:0, null, new UV(0, 0), new UV(1, 1), new UV(0, 1 ) ); texturedShape.addFace(f); texturedShape.addFace(f2); texturedShape.material = new PhongBitmapMaterial( Cast.bitmap (faceBitmap) ); _scene.addChild( texturedShape ); Please note: vertex assignments would be in the form new Vertex( 0, 0, 0 ), etc. I'm using the above for clarity in troubleshooting. Can someone please explain to me how the UV assignments can be made to spread an image evenly across multiple faces? Any help is greatly appreciated!
