DNA File Size Reduction

Hi All,

I am exploring the ways to reduce the FaceMesh size (Currently around 145 MB) of the MetaHuman.

As per my understanding, the DNA file is the major contributor for such a huge size.
Currently, On an average, the DNA file for Metahumans comes around 90MB.

However, 3Lateral claims that the DNA file for each Character will be 400KB as per the article → Gene Splicer From 3lateral & ILM Rogue One on UE4 - fxguide

DNA File holds Descriptor, Definition, Behavior and Geometry data of Metahuman face.
Do we need Geometry data?. Can Metahuman Work properly with Behavior data alone?

I am looking for ways to reduce the Metahuman DNA file size, thus reducing the FaceMesh size (MB) Overall.

Please let me your thoughts and suggestions.

I have same problem, I’ve got over 200 metahuman faces and the size of my metahumans folder is about 45gb. As a test, I exported one and imported it back in to UE5. Now the file size of the imported MH is 8mb instead of 145mb!

33mb for the face mesh after export with export morphs option ticked.
