P: Support cataloging PSB files

You mean saving it to a PSD file? Yes, that is still limited to 2 GB. If you open a file from Lightroom, make it grow beyond 2 GB and then save it, you get an error message telling you the file is too big.

However, I just tested by opening a raw file from Lightroom. I copied the background into 40 layers or so and then saved it as a PSB file, amounting to 8.92 GB. Lightroom shows that PSB file in the catalog after the "Save As" action, didn't have to do anything like synchronizing the folder. So yeah, for me it works and I'm delighted.

Well the size limit is still there... not usefull for me at all.

Thank you, thank you , thank you ! 🙂

Yup, they didn't do too bad after 9 years 

nice, Adobe finally listened to their Lightroom users:
with today's Lightroom Classic release 9.2 PSB files are supported!
(and it really works (just tried it))

Having same issue as well. Please giva at least a workaround. Thank you.

For those looking for a workaround, Sean Bagshaw has posted an update on his approach using Smart Objects.  This version uses a linked smart object -- a more effiicient approach.

but would like to hear from Adobe that this feature is on their development team's roadmap.

They are not going to tell you, unless you work for them or test for them. When it's released, you'll know. Until then, be patient. 

Grasshopper is patient, but would like to hear from Adobe that this feature is on their development team's roadmap.

Andrew! you're still around!! I'm glad - I read a lot of your stuff, like, a decade ago
