Some of my customs Backdrop I normally use.
DasGrain is not included in REGRAIN backdrop. If you have interested, make the download direct from Nukepedia:
To install, just extract the file, then copy and paste the folder "DL_Backdrops" on your ".nuke" directory. If there's no "ToolSets" folder, you will need to create one.
If possible, leave a comment. I hope you like it.
