There are two issues that can affect the Radiant Photo plugin users depending on how their system is configured.
Missing from the Edit menu
Occasionally, Radiant Photo may not show up properly in your Lightroom menu. This is evident if If Radiant Photo does NOT appear when you select Edit In,
- Open up your Settings menu (it’s under Lightroom on macOS and Edit for Windows).
- Choose the External Editing Tab.
- In the middle of your screen, where it says “Additional External Editor,” press the “Choose” button.
- Navigate to:
- Windows – C:\Program files\Radiant Imaging Labs\Radiant Photo or C:\Program files (x86)\Radiant Imaging Labs\Radiant Photo
- Select the “ RadiantLR “ file (this is a .exe file). You will see the “Application:” now says “RadiantLR.exe.”
- macOS – /Application/Radiant Imaging Labs/Radiant Photo/RadiantLR.app
- Now, under the “preset:” drop-down, choose “Save Current Settings as New Preset…”
- Type “Radiant Photo,” and press the “Create” button.
- Then press “OK,” exit Lightroom, and re-launch, and Radiant Photo should now appear under Edit In.
Slow updates for macOS and returning files
Are you a mac Lightroom user? Make sure Lightroom has the needed permissions to see files when you edit with plugins. This can cause issues when using Radiant Photo.When working with Lightroom Classic, it’s essential that it has proper access to files on disk. Otherwise, you might see weirdness, like plugins not working or external edits getting hung up. It can also slow down exporting or even cause files to misbehave.
Just follow these steps. You will need admin access to your machine (username and password too).
- Click the Apple menu and choose System Settings.
- Choose Privacy & Security.
- Choose Full Disk Access.
- Click the + (plus) icon at the bottom of the window.
- Navigate to the Applications folder on macOS and choose the Adobe Lightroom Classic application.
- Confirm permission, you might need to quit and relaunch the application.
While you are at it, repeat the above steps for the Radiant Photo and *Radiant Photo LR *applications.
Things should now work much better. This problem often raises its head whenever you run an OS upgrade (even a minor one). If plugins start to misbehave… give it a check. Now that Lightroom Classic has proper disk permissions on your Mac, the errors should clear up.
