Hi,

 

I have got Macbook Pro M1 Pro (Silicon) with Lightroom Classic 11.1 and the mask subject tool doesn't work properly. It doesn't select the subject anytime. It selects much more abstract shapes. 

 

Anyone knows why I can't get good masks with Mask Subject? Could you help me?

 

I tried reinstall, reboot previously. It's like it can't select the subject never, even with simple backgrounds and chroma key. I attach examples with original images and subject mask selected:

Thanks a lot for everyone

The 'Subject' mask works fine with your originals on my MacBook Pro M1 Pro and Mac mini M1. However, I see from your 'System Info' that you're running LrC in emulation mode (i.e. Rosetta). 'Arquitectura de la aplicación: x64 (emulated)' When I switch my sytems to emulation mode I get similar behaviour to yourself.  I also tried the 'Sky' mask, which seems to work OK. This suggests that the AI  'Subject' mode is either not compatible with emulation mode or there is a bug in the code that hasn'...

I downloaded one of your images and imported it into LrC 11.1 on MacBook Pro M1 Pro and don't experience the issue you describe/demonstrate. I've attached 3 versions of the mask for yoru first image as an example.

Oh that's the mask I expected!

And I can see we have the same Macbook and version.  I'm really really confused about it, because I didn't setup any strange adjust. I only click on the Subject Mask and that's what it mask. I attach a video below.

 

Thanks for the response Ian

It looks like you've already been using a green-screen and blending the subjects into backgrounds. Are your original layered images from Photoshop? I yes, then try flattening the image before saving, then import the flattened version

No, I imported the images directly from Finder to Lightroom Classic and the images are .RAW, .DNG or .JPG

Can you upload one of the original images (ideally the guy with building background) to Dropbox or similar and provide the share link? That would enable us to see if the issue is specific to your setup or the image itself.

Watching your video, it looks like with no mask created you go directly to the desired adjustment brush first. In your case you click on the Select Subject. Seems a bit of a shortcut that might be introducing issues. Might not be what Adobe planned on. This would have been a pre v11 approach.

 

I could be misreading/watching the video.

 

Instead, click on the create mask button, Then select the adjustment brush.

In addition to a sample image, please do the menu command Help > System Info and copy/paste the entire contents here. That will show us the exact hardware and software versions you're running.  LR's AI masking uses Apple-provide AI libraries, graphics drivers, and the graphics hardware to run the selection algorithm, and it's certainly possible that your configuration is buggy.

The 'Subject' mask works fine with your originals on my MacBook Pro M1 Pro and Mac mini M1. However, I see from your 'System Info' that you're running LrC in emulation mode (i.e. Rosetta).


'Arquitectura de la aplicación: x64 (emulated)'

When I switch my sytems to emulation mode I get similar behaviour to yourself.  I also tried the 'Sky' mask, which seems to work OK. This suggests that the AI  'Subject' mode is either not compatible with emulation mode or there is a bug in the code that hasn't yet been mentioned / identified here on forum. Given that 'Sky' works, I suspect the latter. Strangely, 'Subject' mask with my own images work fine in both native and emulation mode.

 

Have you a reason why you neeed to be using emulation mode? If not, then I recommend that you run LrC in native Arm64 mode. This is easy to configure via 'Get Info'. That is, 'Open using Rosetta' should be unchecked as shown in below screesnhot. In the meantime, I'll submit a but report and attach your images.
