The shader layer is a shader through which we can add more textures in one channel. Now go back to the main page of the diffuse layer and again click on the triangle next to the selection of the texture, selecting the layer. To change the color gradient double click on the squares on the ends of the gradient bar. In our case, we leave all the default parameters, except for the left color of the gradient, it changes from black to blue. Occlusion obscures all surfaces in the immediate vicinity of the grooves, and is adjusted in many ways, to which you can access by clicking on the square for preview. The final effect can vary in different lighting conditions and be used for models with a simpler geometry.įirst you create Vray Advanced Material and apply it to the object, in Diffuse Layer 1 add the AO effect to the environment.
In this part, we use a sculpture loaded with, with a form that allows us to better estimate the final effect illuminated by the Area light (right, left and above), and using an HDRi map for the environment.

How to use the AO effect to get a dirty vray metal material? The AO effect can be assigned in all areas in which you can insert a texture, Effect → Ambient Occlusion. Occlusion (abbreviated as “AO”, from Ambient Occlusion) is an effect in consequence of which the surfaces are obscured by their proximity, simulating the absence of light in the most enclosed areas.ĪO is great for imitating dirt and works perfectly if it is superimposed (at the shading level) on another image.

True realism is created from small defects and unevenness’s, and if we are to approach perfection, paradoxically, we must strive for imperfection.ĪBOUT US | CONTACT US | OUR PORTFOLIO | FREE TRIAL| REQUEST FOR QUOTE The main problem is that in reality there is nothing as perfect and clean as rendering. It is not easy to set up a higher-level metal vray, even if the object is well modeled and well-lit. It will be used both as a base color, and as a bump. For a stone material it is even easier, in this case one texture can suffice. In this lesson we’ll see how to simulate mud in the grooves of a 3D model using Vray Advanced Material and the occlusion effect of the environment to add a sense of imperfection that can raise the level of realism in our images, especially in those where metal objects and stones are present.Ĭreate a vray metal material is quite simple: you need to set the gray as the base color and raise the reflection almost completely in the mirror layer. We must strive upwards and begin the ascent to a higher level in the pursuit of extreme realism. If we want to stop being CG3D fans and become real professionals, it’s not enough for us to create the right images from the photographic point of view.
This is an advanced level lesson that will be dedicated to all those who want to start this journey. On the path of extreme realism: imitation of dirt on metal with V-Ray + Ambient Occlusion. Vray metal material in Cinema 4D imitation of dirt on metal
