Elmer Discussion Forum

After running Elmer I get a vtu file that I open in Paraview.
I plan to extract the different bodies and show some of them with a reduced opacity.
However, when I set the a opacity value under 1 (100%) the image disappears.
Do you know if I can set anything in Elmer or there is any filter in Paraview to allow transparencies?
Thank you.

I search some other forums and they relate the issue to graphic card drivers.
I had not had any issue before, but it seems that the problems resides there.
I have tested the file in another computer and opacity is set correctly.
