Sbsbaker: Warning: QT_DEVICE_PIXEL_RATIO is deprecated.

[linkitch]

I've been trying to get the sbsbaker to work, but after going through installing all the prerequisites I'm getting the following error when trying to run the script with PowerShell. What am I doing wrong?

Hi,

For clarity, is the warning the issue or does the baking fail in that no output file is written?

David

[linkitch]

No file is output, I just get the error.

[DavidAllegorithmic]

Is it possible for you to share a sample scene?

[linkitch]

I'm not sure what I can really share? All I'm doing is using PowerShell and pointing it to an FBX.
I've even tried running it on the Big_Rock.fbx located inside the SAT sample folder, I get the same error.

It seems like I'm doing something wrong if I get those errors, but I'm not at all sure what I can do to fix it.

[NevTD]

Just jumping in here as I've encountered the QT_DEVICE_PIXEL_RATIO warning before (unrelated to SAT) and it can often be innocuous (not saying it's the case here).

Out of curiousity, can you run your command with --verbose to see if any relevant details are provided regarding the output?

Code: [Select]

.\sbsbaker.exe ambient-occlusion "D:\Download\Bake Test\ORT3500A hus.fbx" --output-size 10,10 --verbose
Have you also tried baking with the --output-path command, in case it's a permissions issue?

[linkitch]

I was wrong a file actually did get output either way, just not where I was expecting it to show up.
And the verbose command does indeed show that. So I guess it does actually work, just shows that error every time for some unknown reason. Thanks for the help.

It outputs to current directory if no output path is provided.

Are you using a 4k or other high dpi monitor by chance?
My guess is that's what's triggering your QT_DEVICE_PIXEL_RATIO warning.
Either way it's safe to ignore on your end.

[linkitch]

Yeah I'm using a 2560x1440 monitor.

[NevTD]

Figured as much; it's something in the QT5 library probably triggering it on initialization via SAT.

I would say it's safe to ignore it unless Adobe/Allegorithmic says otherwise.
