Here’s the link to the weekly snapshot of darktable 3.9, https://drive.google.com/file/d/1VjDqTLS8LG-jke8YqShI76HoaMCGFeeY/view?usp=sharing. The list of latest changes is at Pulse · darktable-org/darktable · GitHub
the lut 3d module is missing with this build.
I’ll raise an issue on github. The module is compiled in, but for some reason isn’t showing in the interface.
This used to happen some time ago…can’t remember the fix but might be worth checking…
It appeared to be msys related. I checked out several commits that had working lut3d modules, and they didn’t work after I compiled them. I updated my build system again, recompiled and now things appear to be working.
