[TOOL] Mirror shader

EDIT

Last video: water reflections and refraction - WIP 2

See details & screenshots on last post.

Neat mirror shader.

Now, let's go for realtime planar reflections on a floor.

This is pretty neat.

How much control is there over the shader? I.e. can we treat it like a regular PBR shader?

[EdWasHere]

This is pretty neat.

Thanks!

can we treat it like a regular PBR shader?

There are several parts where you can get control:
- First part: you can control metallic, roughness, normal, etc... all things relative to the surface of the mirror. You can add patterns, drawings, to the surface too.
- Second part: you can add and control refraction, etc... all things relative to thickness of the mirror.
- Third part: you can get control over reflections intensity, mixing reflections with specular highlights and refraction, etc... You could also tint or blur reflections here, or add any postprocess effect (grain, bloom, fringe or whatever you want), or mix between neat and blur reflections, according to a "steam map", for example. Or add a postprocess material to the reflections themselves.

So a lot of control.

Now that I have a neat basic shader, i'll post other videos to show more advanced uses of it (like I did with glasses shaders).

Great stuff here, how can i get my hands on this shader? also is it compatible with 4.11? Thanks!

[EdWasHere]

@William K: thank you! I plan to release this shader as a part of a "Glasses shaders pack", i'm working on. I'm working with 4.10 and didn't already test it on a 4.11 preview version. Unless major changes in Epic's source code, it should run. I'll give news about this, each time an official release is published.

This looks amazing mr EdWasHere.

I really would like to have something like this.

Keep up the great work!

Very nice,

Unbelievably, this is the first actually good mirror shader I've seen in UE4.

When do you think your content might be out on the Marketplace? Any documentation until then, or are you keeping it to yourself?

[EdWasHere]

Thanks, guys! Hopefully, it should be available in a few months, as part of a "Glasses shader pack" I'm working on.
Till then, no documentation, I'm affraid. But new videos, as teasers !

Well, looking forward to its release!

This is amazing. How is performance?

[EdWasHere]

Thanks! About performance: that's something I'll have to evaluate precisely to give good informations to potential users.
For the moment, all I can tell is how it runs on my old pc.
My config: Intel Q6600, GTX 560, 4 Go Ram. A high-end pc... of last century!
With a resolution of 1280x720 (both cam & capture), it runs at 50 fps.
With a resolution of 1920x1080(both cam & capt), it runs at 30/35 fps.
I'm really curious to know how it would run on a good actual PC for gamers. I'll test it on various configs and give you these informations.

Looks really nice! Is this done purely in the shader or did you use scene capture and render targets for this?

[Ravneson]

Awesome! Can't wait to see this released!

Amazing work as always. I'm really looking forward for the glass shader pack, please keep us posted!
