How can I get viewport camera frustum bounds in editor.

I need to know the world coordinates covers in the viewport camera in editor. I need camera frustum bounds for this

I assume you trying to DeprojectScreentoWorld. Though even if you don’t - you can check the source code of this node to see where it gets the camera params from

upd: talking about exact question, seems it’s the data you looking for:

	ULocalPlayer* LP = PlayerController->GetLocalPlayer();
	if (LP && LP->ViewportClient)
	{
		// get the projection data
		FSceneViewProjectionData ProjectionData;
		if (LP->GetProjectionData(LP->ViewportClient->Viewport, /*out*/ ProjectionData))

		// < rest of code which is non relevant to problem in question >
