GIMP 3.2.x not recognizing rawtherapee plugin

[cjsmall]

I've used Gimp 2.10 and 3.0.8 and both have recognized the rawtherapee plug-in.  However, neither version 3.2.0 or 3.2.2 recognize it, although the proper files seem to be there.

I installed the extracted AppImage for all 3.x versions.  Here is a find search in 3.0.8 and 3.2.2 directories:

3.0.8:
49-> ffind file-rawtherapee
./usr/lib/x86_64-linux-gnu/gimp/3.0/plug-ins/file-rawtherapee
./usr/lib/x86_64-linux-gnu/gimp/3.0/plug-ins/file-rawtherapee/file-rawtherapee

3.2.2:
75-> ffind file-rawtherapee
./usr/lib/x86_64-linux-gnu/gimp/3.0/plug-ins/file-rawtherapee
./usr/lib/x86_64-linux-gnu/gimp/3.0/plug-ins/file-rawtherapee/file-rawtherapee

So the plugin is there.  From withing the respective programs I open:

Preferences -> Image Import & Export: Plug-In

3.0.8:
${gimp_plug_in_dir}/plug-ins/file-darktable/file-darktaple
${gimp_plug_in_dir}/plug-ins/file-raw-placeholderr/file-raw-placeholder
${gimp_plug_in_dir}/plug-ins/file-raw-rawtherapee/file-rawtherapee

3.2.2:
${gimp_plug_in_dir}/plug-ins/file-darktable/file-darktaple
${gimp_plug_in_dir}/plug-ins/file-raw-placeholderr/file-raw-placeholder

So the plug-in isn't listed.  However, I see no way to manually add a new plug-in to the list.  I never manually added it to other versions of GIMP, it just worked.

Any suggestions as to how I get this listed, and why the 3.2 series isn't loading this or picking it up from the previous 3.0.8 configuration?

Thanks.

You need to add the path of Raw therapee to your preference folders.
The folders are at the bottom of the preference list.
After opening it go to Plugins. Add a folder. (on the top left should be a folder icon with a +, then add a file - when a window pops up go to Windows:C then programs then add the Raw Therapee folder.
This is in Windows 10 - I just tried it with 3.2  I hadn't opened any Raws with the new gimp yet, but had RT on my system.

@cjsmall  This using a Mint 22 VM / Rawtherapee (RT) 5.10 (installed from repo)

It does not surprise me that the 3.2 appimage does not find the RT installation. An appimage is to a certain extent sandboxed.  The appimage will contain the two RAW plugins There is nothing that you can add if RT is not compatible.

   

You can run an appimage with the --verbose switch in a terminal and you can see the Gimp side is loaded.  As you found it does not show in Edit -> Preferences.

Depending on your linux - you might get a Gimp 3.2 from a PPA and that might work.  (..but not an Xubuntu 22.04 you were using in an earlier post.)

Same as your findings, a regular Gimp 3.0.6 (from PPA) install, works ok,  although seems painfully slow ransferring back to Gimp.

Fired up #1 laptop, Mint 22.3 / Gimp 3.2 (PPA) and RawTherapee 5.12 (PPA) and that is working fine.
