• Use the node Save Mesh Paint As Bytes to save all the painted effects / pixel collision etc in your world
• Use the Actor filters parameter if you only want to a save a subset of actors/materials
• If you need to bake textures, check the bNeedsBakedTexturesForSkinnedMeshes parameter
  • Most usecases will not need this, saving just the paint strokes will be sufficient. This also has the advantage of being “non-destructive”.
  • Skeletal meshes with multiple animation poses per paint stroke (and requiring fully accurate reproduction) may want to use this option.
  • Baking textures requires far more disk space than the saving just the paint strokes so only use if required.
  • For more information check out the documentation for this parameter which is provided as part of the Blueprint / C++ API
