UKismetMathLibrary::Conv_IntVectorToVector

function Engine Blueprint Since 4.0

#include "Kismet/KismetMathLibrary.h"

Access: public Specifiers: staticBlueprintPureBlueprintAutocast

Description

Converts an FIntVector (three int32 components) to an FVector (three doubles) component-wise. Commonly used when converting voxel or grid coordinates to world space.

Caveats & Gotchas

• Lossless for the full int32 range — int32 values are exactly representable as double. However if you then multiply the resulting FVector by a voxel size to get world coordinates, keep in mind FVector uses double precision in UE5, so large grids remain accurate.
• The reverse path (FVector to FIntVector) truncates — use FMath::FloorToInt or RoundToInt explicitly to control rounding before the reverse conversion.

Example

Voxel grid coordinate to world location C++

FIntVector GridCell(10, 20, 5);
const double VoxelSize = 100.0;
FVector WorldLocation = UKismetMathLibrary::Conv_IntVectorToVector(GridCell) * VoxelSize;
