Marvelous Designer Alembic versus  UnrealEngine Cloth Physics

Adding to last week's post I'm sharing some more tests and insights on 3D Virtual Clothing physics in UnrealEngine. There's roughly two ways of approaching this; either a pre-baked external simulation (Alembic) or 'Live' cloth simulation reacting to the movement of an avatar in UnrealEngine itself. The movie below shows the principle at work; although the outfits look the same - they are configured differently and serve different purposes. The Pink garment is really accurate and detailed, but pushes hardware performance. While the Yellow garment simulation is less accurate, but light on performance and able to alter in realtime. (note: this mesh is a quick test and needs smoothing and fixes) Depending on the kind of UnrealEngine project, a choice between both setups is made; for instance the Pink Alembic setup is used for recording movie clips, adds or video effects - while the realtime Yellow setup would be used for Live Virtual Production interaction or gaming purposes. I will dive more into the Alembic setup in next updates. Let me know if you have questions about this technology!
