V-Ray | Realistic GEMSTONE Shader
In this tutorial you will learn how to build a realistic shader for a Gemstone. The same technique can also be applied for similar materials such as Crystals, Quartz, Mineral, Diamonds and so on.
We will first prepare our asset with a detailled normal map. Then we will dive into the most important aspects of this shader: Volumetric Translucency. After you understand how this effect works you can create lots of nice looking materials that can be applied to a wide range of objects, including ice and snow or other translucent materials. Finally we will add some procedural displacement to finalize our shader.
I am using 3ds Max and V-Ray 6 in this demo but you can also use identical techniques for older versions such as V-Ray 5, V-Ray NEXT and V-Ray 3. A similar workflow can also be used in other software such as Cinema4d, Maya, Blender and different kind of render engine such as Corona, Octane, Redshift, Arnold, Cycles, CyclesX, Eevee and countless others.
