Ensure occurs if the decal scale is set to a very small value

The variable emitting this ensure (RelativeWorldToDecalMatrix) is not actually used, so this line can be removed.

FDeferredDecalPS::SetParameters
...
		const FLargeWorldRenderPosition AbsoluteOrigin(View.ViewMatrices.GetInvViewMatrix().GetOrigin());
		const FVector3f TilePosition = AbsoluteOrigin.GetTile();
		const FMatrix WorldToDecalMatrix = DecalProxy.ComponentTrans.ToInverseMatrixWithScale();
//		const FMatrix44f RelativeWorldToDecalMatrix = FLargeWorldRenderScalar::MakeFromRelativeWorldMatrix(AbsoluteOrigin.GetTileOffset(), WorldToDecalMatrix);  //we can remove this line
		const FMatrix DecalToWorldMatrix = DecalProxy.ComponentTrans.ToMatrixWithScale();
		const FMatrix44f RelativeDecalToWorldMatrix = FLargeWorldRenderScalar::MakeToRelativeWorldMatrix(AbsoluteOrigin.GetTileOffset(), DecalToWorldMatrix);
		const FVector3f OrientationVector = (FVector3f)DecalProxy.ComponentTrans.GetUnitAxis(EAxis::X);

1. Launch the editor with any project
2. Place DecalActor in the level
3. Set the Decal Fade Screen Size to 0
4. Set the scale of the DecalActor to a small number (0.000000001)

Result:

Ensure condition failed occurs : 

Ensure condition failed: false [File:D:\dev\UnrealEngine-5.0.2\Engine\Source\Runtime\Core\Private\Misc\LargeWorldRenderPosition.cpp] [Line: 52]
