[OpenFOAM] Paraview doesn't allow adjusting opacity

huanghai · July 16, 2020, 04:40

Hi all,

I came across a weird issue in paraview.

I was trying to achieve semi-transparent effect by adjusting opacity level (Properties panel -> Styling -> Opacity), however the entire visual would disappear as long as opacity is not 1.

For example, the whole layer would disappear if I set Opacity to to 0.5 or even 0.99, and the layer would reappear as 100% opaque if I change Opacity level back to 1.

Apart from this, everything else works perfectly. I assume it's a problem with my environment / graphic or a paraview setting I overlooked?

Has anyone experienced this problem before. I appreciate your help very much!

Regards,
Huanghai

Sounds like a graphics driver issue.
After trying out the latest version of PV, make sure you have the correct and most recent driver installed for your particular GPU.

Yes you're right. It was a graphic driver issue.
I installed the correct GPU driver then rebooted, it solved the problem.

Thanks very much!
