Multiple HDR operations at once

[swatop]

I shoot a lot of HDR pics and I would love to be able to use control option on multiple files at once.  I can get three going at a time without a problem but more than three usually freezes LR.  Would be very nice if it would do one at a time and query the rest.  Im working on a new Macbook Pro so it shouldn't be the computer.

Yes, lounching multiple background operations slow down the computer. HDR needs to read a bunch of files (at least 3) and combines them into a heavy HDR file. It's probably on the i/o side (disk access) where there is a bottleneck ... also on recent hardware.

I agree but is there a way to have LR comple one at a time so I can select multiple HDR tasks at a time. I shoot a lot of real estate and shoot around ten bracketed shots per house.  Time is important for me and the agent I'm working for.

Many people have asked for the ability to do batch HDR and panorama mergers.  Please add your me-too vote and details about your situation to this feature request in the official Adobe feedback forum: Lightroom: Ability to batch process Photo Merge (HDR and panorama) | Photoshop Family Customer Commu... .

If I understrand correctly, when you combine three pic to an HDR it works fine. If you try to merge more, for ex. five, pictures  it doesn't work.

It could be a problem with the compatibility of your graphic card or the driver. Try to disable the GPU support.
