UImportanceSamplingLibrary::BreakImportanceTexture

function Engine Blueprint Since 5.0

#include "Kismet/ImportanceSamplingLibrary.h"

Access: public Specifiers: staticUFUNCTIONBlueprintPure

Description

Extracts the original source texture and weighting function that were used to build an FImportanceTexture. This is the Blueprint "Break" node counterpart to MakeImportanceTexture.

Caveats & Gotchas

• Only returns the original inputs (Texture, WeightingFunc); it does not expose the computed CDF/probability data, which stays internal to FImportanceTexture.
• The returned Texture pointer is a weak reference stored at construction time — if the source texture has been garbage collected it may be null.

Signature

static void BreakImportanceTexture(const FImportanceTexture &ImportanceTexture, UTexture2D *&Texture, TEnumAsByte<EImportanceWeight::Type> &WeightingFunc)

Parameters

Name	Type	Description	Default
ImportanceTexture	const FImportanceTexture&	The source ImportanceTexture object to inspect.	—
Texture	UTexture2D*&	Outputs the original texture used to build the ImportanceTexture.	—
WeightingFunc	TEnumAsByte<EImportanceWeight::Type>&	Outputs the weighting function used to build the ImportanceTexture.	—

Return Type

void

Example

Recover the source texture from an ImportanceTexture C++

UTexture2D* SourceTexture = nullptr;
TEnumAsByte<EImportanceWeight::Type> Weighting;
UImportanceSamplingLibrary::BreakImportanceTexture(ImportanceTex, SourceTexture, Weighting);
