And, regarding Alpha and screenshots/ animations, there is a help ticket to expose alpha from the screenshot/ animation dialogs.  https://gitlab.kitware.com/paraview/paraview/issues/14958

Hi Ben,

I wasn't aware of the transparent background -- thanks!

This leads to one question though: any idea why this option isn't available under the Save Screenshot Options when saving a screenshot? Changing the color palette can be done in the GUI under Edit->Settings->Color Palette which gets applied to screenshots but you can change the color palette for just screenshots as well in the Save Screenshot Options. I'm assuming that it's because the transparent background for screenshots doesn't affect the GUI but I think it would be nice to have this option in the Save Screenshot Options as well.

Not sure if you're aware, but there is also the option to write out a
screenshot where the background is transparent using an alpha channel.
It also takes into account translucent geometry. It's under the Advanced
settings in the General tab in Settings (search will also find it).
