P: Export at full res fails on Tiff with particular mask

[John Pane]

I imported a 9138x6310 TIF file and performed numerous adjustments including several masked adjustments.

The image exports fine at reduced resolution (2048x1414) but if I try to export at full resolution Lightroom gives the error: "An unknown error occurred. (1)". If I click "Turn off Masks" the image (without masks) exports at full resolution with no error. The exports are performed with the "Export..." command.

If instead I attempt to export with masks on via Publish Services ("jf Flickr: in this instance) the following error is reported: "Couldn't render image: AgNegative:renderToFile: <AgErrorID>dng_error_unknown</AgErrorID>".

I narrowed this down to one of the 8 masks. If I delete the other 7 masks, the image will still not export at full resolution. However, if I "Reset All Settings" and paste in the mask it will export. So the mask seems to be interacting with other develop settings. 

[John Pane]

The mask consists of just a brush mask.  I reset the effect and it still won't export.

[John Pane]

I deleted the mask in question and recreated it from scratch. The file now exports without issue.

I have saved a virtual copy that exhibits the bug, in case you need more info, log files, develop settings, etc. for debugging.

John, 

Is it possible to share the file?

If you go the Virtual Copy that fails and export it as a DNG it should give us some indication of where to go next. 

[John Pane]

Hi Rikk,

Sorry for the delay. For some reason I did not get a notification that you had replied.

When I try to export this virtual copy as DNG, I get the following error. I turned off embedded preview but that didn't help.

Of course the referenced TIF file does exist on disk and is selected if I click the virtual copy and select "Show in Finder".

[Rikk Flohr: Photography]

What was the original source of the Tiff?  Was it from a scanner?

[John Pane]

No, from PixInsight astrophotography processing software. I have hundreds of such files in Lightroom and have not experience problems with any except this one.

[Rikk Flohr: Photography]

Are you able to share a copy of the file that includes the errant mask?

You would have to share it as a single image catalog since Export doesn't work. 

[John Pane]

I just successfully exported to DNG the version of this image where I deleted and remade the broken mask. That uses the same source TIF. So the failure to export to DNG is related to the broken mask, apparently.

[John Pane]

Yes, absolutely willing to share via a catalog. Right here in this thread or some other way? The TIF is almost 300 MB.

[John Pane]

Zip file with image and catalog is 318.9 MB.

Please post to a Creative Cloud Shared folder, Dropbox, OneDrive or similar and share the link. You can DM me the link if it is private. 

[John Pane]

DM sent. Thank you.

[Rikk Flohr: Photography]

Thanks. I have the files and it is failing on Export for me as well. I will log a bug with the team. Do I have permission to share this catalog and file with the team?

[Rikk Flohr: Photography]

Adding Bug and setting status to Acknowledged

[John Pane]

Yes, you have my permission to share with the team.

Thanks

[John Pane]

Thank you for your responsiveness!

Update:

The cause (which will be fixed in the next update) was due to having brush dabs placed out of the image bounds.  We will handle that contingincy better in the future but if you want to fix your image now, you can go in and clean up those brush strokes.

[John Pane]

Thank you for the follow-up Rikk!

I already solved my problem by deleting the offending mask and recreating it. But I was curious and went looking for the errant brush dab. I certainly had no intention to add such a dab to the mask. I got a glimpse of it but then the mask interface becomes non responsive, and I had to restart LR. Then I tried again and the same thing happened. So I don't think I could fix it if I needed to. And that dab is far out of bounds, not close to an edge. I don't think the UI intends to allow out-of-bound dabs, so the creation of the dab is a mystery. So, the development team may be interested in investiging how it got there in addition to handling the contingency of their presence.
