retrotails | Godot engine - Fancy marble reflection & refraction @retrotails | Uploaded 8 years ago | Updated 3 hours ago
Lazy, inaccurate reflection & refraction, with fresnel and chromatic aberration
Also I suppose the reflection should be inverted, but that's assuming the ball has the refractive index of glass. I like how it looks more like a bubble, though if I was able to make the warping stronger I'd invert the Y axis.
