Epic Games has taken a major step towards all-in-editor workflows. Unreal Engine 5.6 introduces an experimental workflow that allows animators to create and sculpt morph targets directly in the Skeletal Mesh Editor. By leveraging the engine's built-in modeling tools, artists can now edit pre-existing morph targets and sculpt blend shapes while in Play-in-Editor (PIE) mode, dramatically reducing the need for tedious roundtrips to external DCCs like Maya or Blender.

To help tailor future insights, tell me a bit more about your workflow:

Morph target animation (also called blendshape animation) is a technique for animating complex deformations by interpolating between predefined vertex-position shapes. Instead of driving deformation with skeletal rigs alone, artists create multiple target meshes (morph targets) that represent specific expressions or poses; the final animated mesh is computed by blending these targets with the base mesh.

The gap between capturing an actor’s performance and translating it into morph target data has narrowed significantly due to automated tracking software. Next-Gen Apple ARKit and TrueDepth Expansion

uses structured latent spaces and "Morphing Cross-Attention" to generate seamless transitions even between different categories of objects. Real-Time Performance: Modern workflows increasingly use GPU Compute Shaders

Frameworks like Apple's ARKit (with its 52 standard blend shapes) and Epic Games' MetaHuman DNA have created universal standards. This allows hardware like iPhone TrueDepth cameras, specialized head-mounted rigs, and audio-to-expressive-text AI tools to instantly drive any compliant 3D character mesh.

Utilize the Morph Target Tab to "store" a state of your sculpt, allowing you to blend back to it later or use it as a reference for cleaning up details.

The introduction of more robust "virtual mesh" technology allows facial animations to scale better with complex characters. The engine’s native AI integration allows for more intelligent, automated blending between targets. 5. Emerging Trends: AI Twins and Generative Motion
