Quits not displaying correctly with LookingGlassStudio

[CrossVR]

Describe the bug
When rendering a quilt with version 2.3.1 of AliceLG results in a quilt that is somehow incompatible with LookingGlassStudio even though it displays correctly in any other tool that can be used to view quilts.

To Reproduce
Steps to reproduce the behavior:

1. Setup a scene with the default blender cube
2. Render and save a quilt
3. Import the quilt into LookingGlassStudio

Expected behavior
A correctly displayed quilt on the looking glass display.

This appears to be an issue introduced by Blender 4.5, it works fine in Blender 4.4.

What's really weird is that I am unable to find any visual difference with the exact same quilt being rendered with Blender 4.4:

[CrossVR]

Found the cause of the issue, the DPI metadata is messed up when rendering with Blender 4.5 and Blender 5.0:

Changing the DPI to 72 x 72 fixes compatibility with LookingGlassStudio. This is only an issue when exporting as PNG, since Blender does not include pixel density metadata in JPEG formats.

[regcs]

Thank you for the report and digging into the issue. Am I understanding it correctly that it is only the metadata and not the actual resolution that is messed up? And is this something that happens with normal Blender renders as well?

[CrossVR]

The image data is exactly the same, I did an image diff and the only difference between the two images is noise. Normal Blender renders are indeed affected in the same way. I've attached both below:

[CrossVR]

I suspect that this change made shortly after the release of 4.4 has triggered this issue: blender/blender@af1110f

  /**
   * Pixels per meter (factor of PPM base).
   * The final calculated PPM is stored as a pair of doubles,
   * taking the render aspect into support separate X/Y density.
   * Editing the final PPM directly isn't practical as common DPI
   * values often result the fractional part having many decimal places.
   * So expose the factor & base, where the base is used to set the "preset" in the GUI,
   * (Inch CM, MM... etc).
   *
   * Once calculated the final PPM is stored in the #ImBuf & #RenderResult
   * which are saved/loaded through #ImBuf API's or multi-layer EXR images 
   * in the case of the render-result.
   *
   * Note that storing the X/Y density means it's possible know the aspect
   * used to render the image which may be useful.
   */

Since AliceLG uses non-square pixels for most of its presets the X aspect ratio is set to 1.03125. This is roughly the ratio between the 70 and 72 DPI values.

So Blender isn't necessarily doing anything wrong, since it is correct that the pixels in the quilt are non-square. It's just that Looking Glass Studio expects that information to be specified in the filename (a0.56) rather than the image header.

And as the documentation above mentions, Looking Glass Studio could in theory use this information to retrieve the correct aspect ratio even if it was omitted in the filename:

(372 / 682) * (72 / 70) = ~0.56

[regcs]

Thanks for providing the details. So, it is basically a new feature of Blender causing the change.

And as the documentation above mentions, Looking Glass Studio could in theory use this information to retrieve the correct aspect ratio even if it was omitted in the filename [...]

So, when you add the a0.56 to the filename, does Looking Glass Studio display the quilt correctly?

[CrossVR]

No, there is no way to get Looking Glass Studio to display a quilt correctly when a non-square pixel density is specified in the image header. I've tried messing around with other aspect ratios too, but I didn't get any closer to getting it to display correctly.

[regcs]

Okay, then I am not completely sure whether this is something to be fixed in the add-on or in Looking Glass Studio.

Maybe @alxdncn or @BryanChrisBrown have any thoughts on this?

[BryanChrisBrown]

oh wow, this is a new kind of bug, never seen this before!

I'll have to dig into why this causes issues in Studio. Thanks for going in depth here @CrossVR @regcs !

[BryanChrisBrown]

I think the solve for now may be to recommend formats other than png, for the time being at least. It'll take me a while to dig into this in studio.

[CrossVR]

@BryanChrisBrown Thanks for digging into it. Do you think it'd also be possible for LookingGlassStudio to use the DPI metadata to calculate the correct aspect ratio in case it's missing from the filename?

I think the solve for now may be to recommend formats other than png, for the time being at least.

That would only be a temporary workaround as JPEG can also store the DPI and those will have the same issue when imported into LookingGlassStudio. It's only a matter of time before Blender will start adding that metadata to JPEGs as well.
