A See-Through Window Effect Made With Unreal Engine

The effect was made by Alex Blintsov for an upcoming game Furnish Master.

Solo Game Developer Alex Blintsov, a.k.a AlFlakky, has recently demonstrated an amazing window shader with a see-through effect made in Unreal Engine for Furnish Master, an upcoming furnishing simulator the developer is currently working on. According to the creator, the effect was achieved without post-processing or separate rendering by only using a background scene under the floor and Custom Depth masking to make the floor transparent only the window is

"Window mesh is a plain, which is hidden from a user (”Render in Main Pass” disabled), but it has Custom Depth enabled," Alex commented on Reddit. "What I do next, is build a background scene under the floor. The floor (the one with room shader and underlight) has a transparent material. In opacity, I pass this custom depth buffer with Screen UV, so it matches with a window shape from a camera perspective. This way floor is transparent only where the window is. It also works with any number of windows."

@Rossetti Raffaele Hi! "FM" developer here.

No, this is not the same effect. Shaderbox uses a "Parallax" effect to create 3d image right inside shader(material). I just use some transparency trick to show a scene under the floor, which really exist there instead of being drawn by a shader. My approach a bit more expensive in terms of performance, but it allows to show real scenes with proper lighting and even animations.

"Did you made outside Material Editor?
It's a separated Blueprint?"
Hi! Thank you!
No, this effect is done by making three things.
1) Disabling rendering of a window plain, but enabling rendering custom depth and custom stencil.
2) Making a scene under the floor
3) Adding masking to a floor by custom depth mask the window generates.

So it does uses materials and some scene setup.

another approach is to do the ray-plane math and clip pixels

@Alex Blintsov, beautiful effect!
Did you made outside Material Editor?
It's a separated Blueprint?
I liked the possibility of animations and time of the day.

Best Regards!

I think, but I coul be wrong, is the same effect achieved with Shaderbox for interior.
