    mirror material?

    this is UE3:


    why is this not possible to do in UE4? how long should we wait until it will? it is an absolute must for almost any scene.

    Actually it is possible -> take a look at the reflection demo. There you can find a mirror material

      actually it is not possible -> THIS is not a mirror. its a live camera footage broadcasted on a screen. check the youtube link above, thats a mirror, and that is Unreal Engine 3. the SceneCaptureReflectActor is missing and its not possible to do without the missing actor. thus something like window or mirror is impossible to render realistically. and i wonder why is it missing? im sure it wont be a big deal to implement the actor from udk that should be there in the first place. its an absolute essential feature

        Hi, i am the author of that UDK bathroom demo.
        and i can confirm, realtime reflections like that are impossible to achieve in UE4 without the missing SceneCaptureReflectActor.
        Which is really mind boggling to me. Why on earth would you discard a feature as essential as that?

        Is there a way of getting this request to the right ears? cause i would love to see the SceneCaptureReflectActor implemented ASAP

        This is how realtime planar reflections worked :

        and i cant think of any good reason why this should be impossible to do in UE4.

            i need the realtime reflection too.
            Hope they listen to use.

              Jazvecina,

              Where is that bathroom sample scene located?

              Thanks

                    you have to use cubemap, i know it is not real-time but so far it is best solution

                      right, but that would look really horrible.
                      so it's not really a solution

                        Cubemaps - real time or not - are not a replacement for mirror surfaces which require maximum accuracy

                        This gave some hopes but unsure how it evolved: https://www.youtube.com/watch?v=Q4P0SdDANvo

                          Well, that one is probably made with the Scene Capture 2D Actor. and it looks really fake.
                          The problem with that is, that the 2D actor is static no matter the players position in space. its more like a TV screen, not a mirror.

                          A mirror setup must have a reference plane, it must be aware of the players position in space, and it must evaluate the reflection angles depending on where the player is and where is he looking.
                          Which is essentially the UDK's SceneCaptureReflectActor

                            Yep and that's what he's trying to achieve, change the reflection camera transform based on the player POV. I know he has a WIP thread somewhere on the forum discussing the issue.

                              Have a look at this thread. It´s not perfect, but works.
