[TUTORIAL] Fog Of War

[stunder]

i’ve managed that it lags in this part of the code…

void AFogOfWarManager::Tick(float DeltaSeconds) {
Super::Tick(DeltaSeconds);
if (FOWTexture && LastFOWTexture && bHasFOWTextureUpdate && bIsDoneBlending) {
LastFOWTexture->UpdateResourceW();
UpdateTextureRegions(LastFOWTexture, (int32)0, (uint32)1, textureRegions, (uint32)(4 * TextureSize), (uint32)4, (uint8*)LastFrameTextureData.GetData(), false);
FOWTexture->UpdateResourceW();
UpdateTextureRegions(FOWTexture, (int32)0, (uint32)1, textureRegions, (uint32)(4 * TextureSize), (uint32)4, (uint8*)TextureData.GetData(), false);
bHasFOWTextureUpdate = false;
bIsDoneBlending = false;
//Trigger the blueprint update
OnFowTextureUpdated(FOWTexture, LastFOWTexture);
}
}

It triggers if bIsDoneBlending==true, and then it lags. If i disconnect in blueprint setting this bool to true - its not lags. Then i thought, that its an OnFowTextureUpdated lag, so i connected setting bool in bp and disconnecting everything from event ‘OnFowTextureUpdated’, but it still lags. So i made a conclusion, that this part of code making system lag, but i dont understand, why it lags on win 10!
