There are quite a few different types of asphalt and it can look different depending on its age. This shader is for a pretty fresh and dark look. Scatter a bunch of rocks on a plane and render out a zdepth pass. Clip in the whites to make sure the topmost stones make a smooth, flat surface. After that, the…
Clay is a straight-forward material with a basic set of maps. Here is the setup: The interesting part here is the Normal map, which adds the finger indentations and other distrotions to the surface. It is best to sculpt it in Zbrush, on a simple plane ("Brush Wrap" on to make it tileable). Try different sculpts for different results.
This is a rather interesting material. In the real world, pearl is made up from many different transparent layers with different colored reflections. When combined, these layers give the iridescence effect. Let's start with the first layer. We need a light Diffuse color (with slight bluish/beige/pink tint, depending on the type of pearl). The reflections are colored and then blurred…
Porcelain is different from many other stone-type materials, because it has translucency. To achieve this effect, we are going to use VrayFastSSS2 material. First deal with the basic settings like IOR and Specular layer. The reflections are pretty strong and quite sharp, so use a very light color for Reflections and a glossiness value of 0.98. Fresnel IOR is set…
One of the main characteristics of plaster is that it looks flat when compared to other materials. The light and shadow play is not as strong. Microscopic irregularities cause this effect and it can be simulated in Vray by raising the Roughness parameter a little bit (0.25 in this example). The diffuse map is a photo, adjusted so that the…
Let's go back to a single layer material and convert it to a rough granite shader. The main difference here is that the material needs to have lower glossiness and a rough looking Bump map (in this example, we are actually using a Normal map for higher quality results). A bit of color variation in the glossiness is good. And here…
Here is our reference, which we will try to achieve. The Diffuse map is a simple, tileable photo of sand (the example here is a crop). Reflect and Gloss maps are based on a greyscale version of the Diffuse, but with some brighter specks added in. These brighter dots simulate the little quartz grains in sand that sometimes are much more…
This is a very popular way to show off the object's wireframe. Basically, you want to combine the AO and Wireframe shaders together to show both the shape and polygon structure of the model. There are quite a few ways to achieve this, but this is the best approach. Take your AO shader and change the Dirt map to Composite…
Traditional wireframes can be rendered by taking a regular VrayMtl and sticking a VrayEdgesTx map in the Opacity slot. This usually looks fine for very simple objects. You can adjust the wireframe thickness in pixels or real world units (we think the default setting of 1 px looks best). For complex objects, this transparent wireframe look can be very messy…
To create an AO shader, use VrayLightMtl and VrayDirt map. Use VrayLightMtl so that it does not receive any additional shading from the lights in the scene. It's a good idea to raise the Dirt subdivs, so that there is no ugly noise in the occluded areas. If you are going to use this shader to create an AO pass…
