You know this effect from looking at a glass of water, or very thick glass.Īir has a refractive index of 1.0 – so light rays travel through it in a straight line -, water has an index of 1.33, window glass 1.52, and, for example diamonds have an index of 2.42 – they bend light quite heavily.įor further information on this topic, feel free to have a look at the Wikipedia article. The Refractive Index slider determines by which factor light is being bent when traveling through a transparent surface.
This menu allows you to choose a color that should be added to any semi-transparent areas of your material. If you’re using it combined with a transparency map, it will define the maximum opacity, so white areas on said map will appear as opaque as you’ve set using this slider. The Opacity slider controls the overall transparency of the surface. If you load a colored image, Enscape will automatically convert it to black and white, so you don’t have to worry about that. Grey areas will appear partially transparent, such as glass. It refers to the Opacity value, so a black area (which equals zero) on the image used will result in a perfectly transparent portion of the surface, while a white area will appear perfectly opaque. The Texture parameter allows you to control the transparency using a 2D image, a map.
