Hi there!
So I am currently using Vegas Pro 16. Not sure if this is something that has changed in newer versions or not, so please let me know if that's the case.
I have used NewBlue FX since Vegas was Sony Vegas. Back during the SV days, NewBlue FX presets would have all their preset previews in the Video FX tab. Nowadays, I have to choose the one (Default) option under each plugin and scroll through a separate list of presets with no previews until I find what I want to use. The only "fix" I have so far is to select each individual preset and rename and save each of them one by one as their own presets so I can actually see them in the Video FX tab. Is there some other workaround to this?
EDIT 8/1/22: Fixed! Turns out a more recent update was all I needed.
