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.
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.
Creating Morph Targets at runtime will invalidate existing Morph Targets available in editor.
Base File
Mesh Morpher FBXInput Structure (by ref)
FBX File and Import Settings of the Base FBX.
Morphed File
Mesh Morpher FBXInput Structure (by ref)
FBX File and Import Settings of the Morph FBX.
Name
Name
Morph Target Name.
Target Mesh
Skeletal Mesh Object Reference
Target Mesh to project Standalone Morph Targets on.
Max LOD
Integer
Maximum LOD Index on the Target Mesh to project the Morph Targets
Vertex Threshold
Float (double-precision)
Maximum Distance threshold between a vertex in the target mesh and a vertex in source mesh, at which they are considered to be correspondent.
Normal Incompatibility Threshold
Float (double-precision)
Normal threshold at which a triangle is deemed as incompatible. This helps to avoid triangle flipping during Projection.
Smooth Iterations
Integer
Smooth Iterations steps used to Smooth the resulted Projected Deltas.
Smooth Strength
Float (double-precision)
Smooth Strength used to Smooth the resulted Projected Deltas.
Smooth Type
EMeshMorpherSmoothTypes Enum
Smooth Type used to Smooth the resulted Projected Deltas.
Return Value
Boolean
Returns true if the Morph Target was successfully created.
