[Paraview] ParaView unable to adjust object opacity

[Yu Xiang]

Hi,

 

I downloaded the ParaView Binary Installers
(ParaView-5.4.0-Qt5-OpenGL2-Windows-64bit.exe) from
https://www.paraview.org/download/ and installed it on my Thinkpad T430
which is running Windows 10. I was using ParaView for the first time and
found two things puzzling:

1.       When I open ParaView, the default window looks like the following.
There is a small black square on the bottom left corner in RenderView1
(circled in red). I couldn't figure out why it showed up there.



2.       Then I opened the first Example Visualization and selected Clip2
under can.ex2. When I tried to adjust the Opacity under Styling in the
Properties tab, any value other than 1 will make the object in the
RenderView1 window disappear like the following:



I tried other examples, and similar things happened. I couldn't figure out
why.

 

Does anybody know what might be going on and how I can fix it?

 

Thanks,

Yu
