RL_out_sharp outputs only one random image from the whole batch

Hello!

I have installed the LUA Script pack downloaded from GitHub, activated only one of them - RL_out_sharp (it’s all I want). I also downloaded GMIC CLI for Windows and specified the path to the GMIC executable.

In general the script does its job, however, when I select more than one image in the Lighttable view, Darktable seems to export all of them, but only one, random, sharpened image appears in the destination output folder.

My files and paths do not contain white spaces.

I would appreciate you help :pray:

Can you run it from a command prompt with the argument -d lua. This will output to a log file in your documents directory.

I tested on Linux and it works for me.

Here is the output of -d lua > log.txt 2>&1

See if there is a file, Documents\Darktable\darktable-log.txt. I think that location is hard coded for windows.

It didn’t show up, however I run -d lua again and now it has some more information:

The error message it tried to print was that exiftool was not found, so it couldn’t copy the tags over. I’ll fix the missing MODULE error.

The error is fixed. The next time you start darktable the fix should be pulled down automatically.
