The ULTRAGlass shader is a high quality, highly customizable glass shader which comes with 6 meshes, 5 materials and 15 preset instances for you to experiment with.
The glass shader allows you to customize the aberration, imperfection maps, normal maps, refraction, caustic and base color, and various other variables, which can be seen in the instance window in the images above.
You can add your own normal and imperfection maps to the glass shader, or disable them completely, the choice is yours!

Have you ever tried to create some realistic looking glass renders in Blender?
If you compare the results you get with the default glass shader with reference images, you will probably notice that it is not possible to get completely photorealistic results this way.
Why? Because the Cycles Render Engine does not use bidirectional rendering. This means it is not possible to get physically accurate caustics or dispersion.
With our Realistic Glass Shader you have full control over all parameters you could possibly need for creating awesome looking renders you would previously have used Blender’s built-in glass shader for, e.g. diamonds, water or glass. Please note that the caustics are still fake, because real caustics are simply not possible with Cycles. But who cares as long as the results are good?
You can turn off the reflective and refractive caustics under light paths in your render settings to reduce fireflies. We do not need this feature because we fake the caustics.
