I would like to inquire about 3D coordinate movement,Vignetting correction, and LUT files

We have found that since the beta version of UE5.3 was used in Aximetry, the function of 3D coordinates can no longer be used normally in Aximetry

I would like to inquire about 3D coordinate movement,Vignetting correction, and LUT files

When we select the viewport normally and select the corresponding LED screen, the corresponding preview viewport no longer shows 3D coordinates. And this is feasible in the old version.

I would like to inquire about 3D coordinate movement,Vignetting correction, and LUT files

We want to know how to use this feature properly in the new version? Is there a bug?

And we have doubts about the production of Vignetting and LUT files: they seem to have been updated, but the document does not provide corresponding operation guidelines, and following the prompts cannot complete these functions normally. Can you provide corresponding operation methods and precautions?

Hi,

There was a version of Aximmetry where the LED Wall's handle gizmo was not visible. This was fixed some versions ago and should work correctly in the latest version (2024.2.0 BETA):

If you have unlocked the LED Wall camera compound, make sure to "Revert In-Place Modifications" after updating Aximmetry. For more information on linked compounds, please refer to this link: https://aximmetry.com/learn/virtual-production-workflow/preparation-of-the-production-environment-phase-i/scripting-in-aximmetry/flow-editor/compound/#linked-compound

The Vignette and LUT generation have seen significant changes in recent versions. They are now designed to guide you through the process without needing to read any documentation. If you encounter any issues or something is unclear, please report back so we can further improve the process.

We have documentation about these topics in LED Walls available here:
https://aximmetry.com/learn/virtual-production-workflow/preparation-of-the-production-environment-phase-i/led-wall-production/using-led-walls-for-virtual-production/#color-matching-using-a-lut
And about Vignette in general here: https://aximmetry.com/learn/virtual-production-workflow/preparation-of-the-production-environment-phase-i/green-screen-production/how-vignette-correction-could-be-useful-for-you/
Please note that these documents may be somewhat outdated due to the recent changes in both features.

Warmest regards,

Ruizhong

During the utilization of Vignette, we utilized a large TV to display a pure white image for calibration. Despite our efforts to capture the picture with the camera, we were only able to achieve 99% accuracy, falling short of the required 100% for proceeding to the next step.

The initialization of the LUT file encountered an issue related to white and black levels, preventing us from proceeding. I will attempt to resolve this later. Alternatively, do you have a relevant example video for reference?

Hi,

The accuracy of the Vignette is measured by the percentage of the screen's scanned surface. If you haven't reached 100%, it indicates that an area(s) has been missed. This missed area should appear in red with a yellow outline. You need to locate and scan this area to proceed to the next step.
If, for some reason, the missed area is not highlighted or cannot be found, please provide a screenshot or video of the process. This will help us identify the source of the issue.

In the LUT measurement, any areas where the camera does not see the LED wall will be shown in magenta. There could be several other issues, as mentioned in the text about black and white colors. If you are still having trouble, it is best to share a video or screenshot of the camera's input.

Currently, we do not have any up-to-date tutorials or reference videos available on these topics. However, we are working on creating them, along with more detailed documentation of the entire LED Wall production process.

Warmest regards,

Hi Ruizhong,

The newest version of Aximmetry (2024.3.0 BETA) fixes the issue where the Vignette Scanner would stop at 99% when the input was 2160p. You likely encountered this same problem.
The version also includes other LUT and Vignette related fixes: https://aximmetry.com/learn/software-version-history/
