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

[Christoph Schweigi]

Thx, I want to fuse two structures of radiologic datasets. Both are from brain vessels. The embeded model is the fluidic pattern (solid color) and the other outer model is the morphology (transparent with less opacity) one. 

Thx,
Chris
Ps: I am currently texting from my phone but if u want I can give u afterwards a link with the datasets?
