[Paraview] one 3d model transparent color + one 3d model normal color for vrml

Tue Jun 12 11:38:15 EDT 2012

Hello Sebastien,

thx for your help. You are right it works great with a solid color. I only would like to have a bigger selection for them. Cann´t I take a color table? Or can I import colors?
I tried to add a scalar but the scalar disappears  after the export.
Is there a opportunity to save the opacity as well in the vrml file?

Have a good day,
Chris
