Texture Frequency Equalizer Copernicus HDA (Free)
A couple of weeks ago I ported my old Nuke tool to Copernicus-
It's called Texture Frequency Equalizer and is based off of "Texture Management" tools from DaVinci Resolve and BaseLight. It's used to sculpt the softness and sharpness of different frequency bands of your images which can be super helpful to art direct CG renders!
The docs and (free) download are on my github if anyone is interested in trying it out!

For those interested you can read more about the Modulation Transfer Function, it's not something I see brought up in CG communities very much, but DPs, colorists, and compers might be familiar with the concept!
