General Issues and Bug Reporting

Summary

Can anyone confirm that the depth processing plugin for Metahumans works in the 5.6 release.
After adding the plugin to a new project I get "The following modules are missing or built with a different engine version:

MetaHumanMeshTracker
MeshTrackerNodes"

Is the only solution to build unreal? If so, is there a guide?

Hey @wafumaster,

It sounds like you need to update the Depth Processing Plugin - we released a new version alongside the full UE5.6 version.

You should see an update within your Epic Games Launcher.

Cheers

Root cause: I upgraded from 5.6 preview to 5.6 release. Removing the upgraded version and installing from scratch fixed it. Thanks.

Hi James, It is possible to get some sort of user facing output to indicate the quality of the depth map. The old command line tool with GUI at least let you dynamically adjust the blur factor and the final output gave an MSE value as an indicator. I don’t see that we get any means to validate the quality at this stage, or did i miss something?

Hey @jeC3d,

Did you mean the calibration error?

If so this is still available, admittedly a little harder to find, it is in the log eg:

[2025.06.10-08.52.50:002][555]LogMetaHumanCalibrationGenerator: Display: Successfully calibrated with reprojection error of 0.210428

That was the one. Thank you for highlighting it for me.
