class NBTRILINEARINTERPOLATION_API UTrilerpMeshComponent
    : public UDynamicMeshComponent;

Reflection-enabled

Specifiers:

  • ClassGroup = Rendering

Meta Specifiers:

  • BlueprintSpawnableComponent

A DynamicMeshComponent which supports trilinear interpolation of the underlying mesh.

Properties

  • Lattice

    public:
TArray<FVector> Lattice;

    Reflection-enabled

    Specifiers:

    • BlueprintReadWrite
    • EditAnywhere
    • EditFixedSize
    • Category = NBTrilinearInterpolation

    Offsets from interpolation lattice corners. Do not modify length.

    First four values represent the bottom four corners, second four the top four corners.

    Because this is a list of offsets, if all vectors are zero the trilinear interpolation will not modify the mesh, it will just return the original vertex positions.

    Reflection-enabled

    Specifiers:
