Prior to the most recent updates to Lightroom and Photoshop I could select a group of images in Lightroom and export them into a single smart object layer in Photoshop. This was very handy for doing some things like time lapse compositing, for example, using the smart objects layer menu to apply mean or median averaging to them. If I try it now, it exports only the 'most selected' image as a a smart object layer and the other image files are not imported at all. Now I have to select all the images and export as layers into photoshop, then select all the layers and convert them to a smart object before I can apply the Smart Objects Stack Mode effects.
To make problems even worse, Creative Cloud no longer offers a way to roll back Lightroom to a previous version. Photoshop can be rolled back from the current 16.1.2 to 16.0.0, but then Lightroom's current version, 1067055, doesn't export to Photoshop, at least using the various scripts. Since I do a lot of this kind of composite work, this will slow down my workflow considerably and I need a way to get the previous ability back. I tried to use ACR to do this and it just opens each selected image as a separate smart object document in Photoshop; I need them to be all combined into a single layer smart object as before.
Does anyone know if there's a new way to do this? Or was it accidentally lost like it seems every single update since 16.0.0 has done with each update trying to fix previous accidental feature removal but adding new accidental feature removal instead. This is getting kind of old, by the way. If I can get back to what I had with Lightroom CC 2015.3 or 4 and the previous version of Photoshop CC 2015 I think I'll just leave them alone and forget trying to upgrade. Even though I read the details of the upgrade and checked the forums to see if anything obvious showed up, I have not seen this issue noted, so it's probably one of those things that only a few of us like to use and so it affects only a small number of users.
When I say Lightroom can't be rolled back to previous versions, I need to be clearer: I mean it no longer allows one to roll back to a previous version of the current master version; i.e. from 2015.5 to 2015.4. Removing Lightroom and reinstalling it installs the latest version. However, it's possible to roll back Photoshop from 2015.1.2 to 2015.0.0. I'm not sure how to get to incremental versions in between because there is no longer a way to see all the increments, as far as I can tell.
think the issue is on the Photoshop side, not Lightroom. I too have experienced the same issue trying to open multiple images in Lr into Ps. Lr will initiate the launch of Ps if not already open but that is as far as it goes.
Today, I attempted to load multiple jpegs into one document in Ps CC 2015.5 File --> Scripts --> Load Files into Stack. Just to test Ps, I tried Automate --> Photomerge and Automate --> Merge to HDR pro.
Once the files are selected and I click OK, nothing happens.
