I was trying to work out why changes to my default pp3 file weren’t taking effect as I’d put the profile in the RawTherapee folder. Turns out it’s in the RawTherapee4 folder:
pete@kanga~/.config $ ls Raw*
RawTherapee:
batch options profiles
The .config directory suffix is the same as the cache name suffix given at configure time via -DCACHE_NAME_SUFFIX=..., see RawPedia. Maybe you’re just pulling and compiling since ages and didn’t change the suffix…
