Once upon a time, I downloaded the trial version of the HitFilm Plugins and deleted them once I'd finished taking a look.

Now, although the plugins don't show up in the Effects or Transitions window, a load of empty HitFilm folders show up in the plug-in chooser window (see attached image)

Anyone know how I can get rid of them?

(I also now have a full, non-trial version of HitFilm Ultimate 2 due to the Vegas 13 upgrade but I presume that's irrelevant since its effects are not part of Vegas in the way that the plugins are)

Try deleting

plugin_manager_cache.bin and svfx_plugin_cache.bin

in the AppData folder

users/"username"/AppData/Local/Sony/VegasPro/13.0

I have seen newly (un)installed items not show up in one of the plug-in lists and deleting these cache files causes Vegas to rebuild the files the next time you start Vegas and that cleaned things up for me.

Excellent, thank you. I'll give that a try.
