I've installed DaVinci Resolve 12.1 on a new partition. When I load existing projects I no longer have access to the OFX plugins. In the Open FX Library the Red Giant plugins do not appear, and in settings for any particular applied plugin, it reads:
No parameter is exposed to user
[com.redgiantsoftware.universe_glow_diffuse_glow_ofx] is NOT
I've reinstalled both Davinci and Red Giant Universe.
