Got finally my model up but the colors don't show up. I did an stl from my model but I could have exported in obj or else. I use Blender . Does somebody would know what I did wrong or missed at that level?
Thanks in advance. http://shpws.me/o4WJ
The STL file format has no container for color or texture information, all it can transport is a triangle mesh.
You need to upload a VRML or X3D file, either with colors "vertex mapped" to points on the object or as
a ZIP archive that contains both the VRML/X3D file and its associated png or jpeg texture file.
