Known Issues and Limitations | MetaHuman Documentation

Scaling Joints not directly supported (Limitation)

Description

Arbitrary scaling of joints requires the reciprocal transformation to be applied to deltas, something that at present time doesn’t happen automatically.

Workaround

You can use the Scale Command from the DNACalibration library (that is part of MetaHuman for Maya) to change the scale of a DNA file created using the Expression Editor. To use this library, import the dnacalib2 module in Python.

The Unreal Fest Presentation of MetaHuman DNA features an example of how to use this command (and others), albeit using the previous version of the DNACalibration API.

Preview meshes won’t be created, and a warning message will be displayed indicating which expressions couldn’t be previewed..

Workaround

A workaround is not available at this time.
