Standalone Morph Target
Standalone Morph Targets are a custom implementation of standard Morph Targets.
Standalone Morph Targets are a custom implementation of standard Morph Targets.
This new type of asset format allows users to store Morph Targets as standalone assets which can be visible in Content Browser.
The usage of Standalone Morph Targets is different from standard Morph Targets and the main purpose here is to allow transferring, baking and projection at runtime, easier, without interfering with the existing Morph Targets.
Standalone Morph Targets are exposed to blueprints and there are several nodes and tools that allow users to manipulate them at runtime.

Project Standalone Morph Targets to Morph Targets
Projects an array of Standalone Morph Targets on a Target Mesh and creates Morph Targets on the Target Skeletal Mesh.
Projects an array of Standalone Morph Targets on a Target Mesh and creates Morph Targets on the Target Skeletal Mesh.
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.
You can learn more about Standalone Morph Targets here.

|---|---|
Morph Targets
|

Target Mesh
|
Target Mesh to project Standalone Morph Targets on. |
Max LOD

Vertex Threshold
|
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
|
Normal threshold at which a triangle is deemed as incompatible. This helps to avoid triangle flipping during Projection. |
Smooth Iterations
|
Smooth Iterations steps used to Smooth the resulted Projected Deltas. |
Smooth Strength
