This article explains how to transfer pre-existing UE morph targets to the final meshes generated by mutable.
= Transfer Pre-Existing UE Real Time Morphs Targets
1) First of all the feature needs to be enabled in the Customizable Object Properties tab by checking the checkbox **Enable Real Time Morph Targets** .
This is an opt in option per Customizable Object and should only be enabled when this Customizable Object have meshes with morph targets that are wanted to be transferred. Be aware that by enabling the feature more memory will be used.
2) Next, select which morph targets need to be transferred to the mesh generated by mutable. This is done by specifying by name at each SkeletalMesh Node which morph targets need to be transferred to the final mesh. Go to the Node Properties tab and add as much elements as needed in the property **Used Real Time Morph Target Names**. Then specify by name which morphs have to be transferred.
>In this capture, only "Fat" and "Slim" morph targets will be transferred to the final mesh.
This needs to be done for every mesh and sub-mesh that will contribute to the final output. If two or more sub-meshes have morph targets with the same name, the resulting mesh will have them merged such that all vertices of the final mesh affected by a morph target with this name are driven by the same curve.
