How to make this weird effect

How do I make this weird effect on a part in which it displays sky in it’s top face but distorted and then has every other face in pitch black like this:


Any help is appreciated thanks.

Looks like a highly reflective part reflecting a custom skybox. It’s possible that there are black decals/surfaceguis covering the sides, or maybe the sun angle/brightness is set up just right to only reflect on top.

Could that be negative reflectance? Setting the value to negative numbers gets weird results similar to that.

The thing is that the skybox is completely different from what the part is reflecting, still, I’m going to try doing the decal thing.

I’m gonna try doing that thanks

If the sky is what it shows in the pic, which is pitch black, you could achieve that with an inverted black sphere, or a by building a large cube in the sky out of parts with black surfaceguis on them. Then you still have your skybox asset which is reflecting on the reflective parts!

Pretty sure that’s the Reflectance property on a really high value because I tested negative reflectance and it doesn’t do anything. Another method: they might’ve put a highlight with OutlineTransparency set to 1.

example with red highlight:


no highlight:

more reflective, less transparent highlight = more disturbed


0.6 fill transparency, 4 reflectance
