I performed an Export to X3D on the attached blend file which contains two plane objects which have an image texture. The first plane object has an ImageTexture with a type of "Image or Movie" and a Mapping coordinates = Generated and projection = Flat. The corresponding plane shape in the exported X3D file does not have the ImageTexture assigned to it. For the second plane object I have the same configuration for the Image Texture as the first plane but for the Image Mapping configuration I set Repeat X=2 Y=2. The Exported X3D file did not have a TextureTransform with the scale="2.0 2.0" to repeat the Texture pattern. This is what I expected the Exported X3D file to contain but the ImageTexture and TextureTransform nodes were missing from the Appearance node.

I am using the blender version 2.56 r34103 on a windows XP machine. Attached are my blend file and imageTexture I used for this example and the Expected X3D output file.

I am trying to reproduce the ImageTexture functionality found in this video tutorial.
