V-Ray Procedural Mud Shader

In this video we will add a realistic mud effect to a whole car. We will use a very simple procedural workflow which does not require any additional preparations such as additional UV's or anything similar. As everything is procedural it will stay fully parametric and allows for maximum adjustability.

You can use this technique to quickly add procedural details to your assets. Like this you can texture a huge amount of assets very efficiently. We will discover what are the advantages of procedural masks and why you should use them. I will then show you my preferred way how to create an easy to control render setup for a Procedural Mud Effects and walk you through each step. We will discover the basics of Ambient Occlusion or VRayDirt and how we can use VRayTriplanar Textures to procedurally project any kind of details on our assets. 

We are 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.
