I am trying to use an action and I keep getting the message: The Command Lighting Effects is not currently available. I am using Photoshop CS5 on a PC. Does anyone have any suggestions about what this might mean?
It means »Lighting Effects« is not available – seems pretty clear …
Filter > Render > Lighting Effects is, if I remember correctly, 32-bit, so if you are running Photoshop 64-bit you may have to restart with the appropriate settings.
OK, so maybe I didn't word my question precisely -- I do understand what the words "not available" mean. The issue was that I didn't know why it wasn't available. The second part of your answer seems to have actually given me the info I was looking for -- indeed I am running Photoshop 64-bit. I just saw on the NAPP site that in the new CS6 version this should not be a problem very soon.
Actually the windows cs5 64 bit version should have Filter>Render>Lighting Effects.
Did you look under Filter>Render>Lighting Effects to see if the filter is there?
Perhaps the action itself is at fault or the documents color mode and/or bit depth doesn't support the lighting effects filter.
Ah, hadn’t thought of that; but with Actions and Scripts one has to keep those things in mind as not every operation is possible on any image (depending on Color Mode, bit-depth etc.).
Best to include a check (or change) in the Automation to ensure proper conditions.
