full color sandstone, X3D, no color in preview

    I having no luck getting colors to properly work with my 3D model.

    * I'm using solid colors (not UV patterns) and a .x3d generated by MeshLab.

    * I can reimport import the triangle2.x3d file using MeshLab and it has the right colors.

    * I can see that colors are included in the XML data structure.

    * When uploaded to shapeways the preview is monochrome.

    Does anybody know what's going wrong? Does anybody have an example .x3d file that includes static colors? Thanks for the help!

    Does it work if you upload just the x3d file (either as-is or zipped, but without the unreferenced and
    unneeded.png file?)

    Got it now - the x3d importer at shapeways does not seem to understand RGBA colors, only RGB.
    (I used view3dscene to export your file in "classic encoding" - x3dv with mostly vrml2 syntax, which
    makes it more human-readable and then changed "ColorRGBA" to just "Color" and deleted the trailing "1"
    in each entry. No doubt there is an easier way, but I am still more familar with archaic text editors than
    with MeshLab)

    Thank you for the help. With your edits the file uploads correctly. Since other uses may have difficulty with encoding color for sandstone printing I'd like to suggest that you include some example files for colored and UV mapped surfaces. Then when there's a problem the more technically inclined can at least have a prototype for a "properly formatted" file. The page to which attachments would have helped me is the following.
