Mirror Material with Roughness

[GreenWolf]

Hi,

i want to make a mirror with the roughness setting of the material + the metallic value, but it don't works right .

With roughness 0 and metallic 1 i am getting a mirror but the mirror only reflects things what the player camera is seeing too.
If i look with the camera in the mirror from the side, so that i can see the wall in front of the mirror too, then i can see the reflection correctly,
but if i rotate the camera so that the wall is not visible to the player camera, the reflection disappeared too.

It looks like some occlusions effect, if i move the camera closer to the mirror i can see that the ground behind the camera turns into black and don't
getting reflected anymore (Like a fog of war in a RTS Game) and if i am very near to the mirror and the player camera can only see the mirror, i see nothing reflecting in the mirror.

Thank you for your help

You can use static lighting and reflection spheres to capture the angles SSR cant. Check out the screenshots here to understand what's going on: https://forums.unrealengine.com/show...l=1#post117216

But you should really look into scene capture 2D actor as a better solution for mirror.

Thank you for your help,
i will take a look into scene capture 2D, i hope i can use the reflection in realtime, static is bad in my case.

Scene Capture 2D as far as Im aware is flat, and only acts like a tv screen. Not like a mirror, as its not parallax corrected. Currently there is no working solution for a proper / perfect mirror reflection.

If you rotate your Scene Capture 2D, you get close to something what looks like a mirror



(Note that the fixed axis depends on the orientation of the mirror)

Thank you all very much,
yes the Scene Capture is like a Display , but the rotation works, the effect is good enough.
Thank you all for your help.

On the image Mars007 posted above, would I create that whole blueprint on the camera that pops out when I first create a "Scene Capture 2D"?

and how exactly would I create that "Scene Capture2D1 from persistent Level" node that is to the far left in the image Mars posted?

[Mars007]

I just dropped a SceneCapture2D in the Level and referenced it in the LevelBlueprint.

And i extended the above version by creating a Mirror-Blueprint that conains a flat surface with the mirror material assigned.
No matter how many mirrors i drop in my level, the SceneCapture will place itself to the nearest mirror and face the player.

The flip is done with UV coordinates on the mesh.

Edit: As a quick solution, flip the coordinates in the Material Graph.

It would be interesting to find a step by step process for creating the blueprint. The mirror is visible in a matinee?

Just download and migrate the mirror to your project.
This project includes two mirrors, to demonstrate endless reflections

...............Thanks

Sounds like you should also be able to get a static reflection using a simple sphere reflection capture as long as you rebuild lighting with some indirect lighting.
