# Create Morph Target from Mesh Files

Grabs the deltas between Base and Morph files and projects them on the Target Mesh and creates a Morph Target on the Target Skeletal Mesh.\
This node requires Base and Morphed files to be FBX/OBJ format.\
Base and Morphed files are required to have same vertex count and order.\
Morph Targets are projected on all Target Mesh LODs.\
Projection is multi-threaded but can be very intensive on meshes with big data.

{% hint style="warning" %}
Unreal Engine 5.0.X requires ***`Use GPU for computing morph targets`*** disabled in project settings. This doesn't apply for UE 5.1 and above.
