Thanks! I have been using it since then. With the new CSP preview reworking (supposedly fixing?) the preview rendering, this preset looks drastically different, and I don't know how to modify it to look closer again since as far as I can see you change the settings in the CSP showroom, but this doesn't appear as a showroom?

New render:
For the time being I am using the Small Tweaks -> Old CSP previews render setting to get the old look, but I wonder what actually changed?
