Hi Metin,

an additional info from me... I use on a lot of projects at work
MoI 3.1 with Blender to print multi colored objects, which are
based on MoI's style colors. I simply assign the styles in MoI
and export as .obj. Once imported into Blender i adjust the
color values in Blender's shader tab Diffuse = Intensity 1.0
and Specular = Intensity 0. After that i export the model(s)
as VRML 2.0 i.e. .wrl files.

If you followed the "Pattern on a Sphere" thread here you
can see a 3D color sandstone print from me.

Regards
Stefan
