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 >
