The cube has a solidify and bevel modifier in its stack to avoid a complete solid glass object. To demonstrate this, we can setup a node network like this using the noise texture. Roughness will change how rough the reflection of the glass is, a high roughness value will make the reflections look hazy while a low roughness value will make the reflections very clear, this can also be controlled with any kind of texture. The color will set the color of the glass, you can also control it through its input with a texture or other kinds of input. The biggest difference is that the sharp method won't take roughness into account and GGX is the only option supported when we get to Eevee. The algorithms are different scientific methods to calculate how the glass will be calculated and they give slightly different results. When we add a Glass BSDF node to the shader graph it comes with a few options: To start we will talk about the Glass BSDF Shader, this is probably the most simple and quickest way of creating a glass material.

Drag from the Glass BSDF output to the Material Output Surface input.Press Shift + A then select Shader > Glass BSDF and place it.If the object has no material add one with the New Material Button.Select the object you’re applying the glass shader to.We will explore glass shaders for both Cycles and Eevee.

Glass can add a lot of realism to our scenes and getting a glass shader right can be key to lighting our scenes in a convincing way. When creating art in Blender there are many cases where we may need a glass shader.
