I attempted to integrate the extended difference of Gaussians from Acerola’s GitHub code into Unreal Engine. Initially, it worked, but when I tried scaling the viewport in both the editor and standalone play mode, I noticed spaghetti-like lines appearing along the screen edges. After troubleshooting, I traced the issue to the “UserSceneTexture” nodes. I suspect this might be a bug, as the problem doesn’t occur when using the “SceneTexture:PostProcessInput0” node. It seems the issue arises because the UV of the “UserSceneTexture” node doesn’t adjust with the resolution.
