Note that this shares a lot of the characteristics of the paint material, so the effect generated is very similar.
This preset has a series of sliders that allow you to adjust refraction (how an object allows light to pass through), as well as the fog color (which adjusts the color the light takes on as it passes through). Note that this preset has a series of different options than the other materials because it actually allows light to pass through it. For the third material, apply a glass preset.It also has a very low diffuse color value (the actual color of the object), but a very high reflection value (which is the color of the light being reflected). Note that this material has a higher glossiness, and also a high IOR, or Index of Refraction, which describes the way that light bends along the surface. For the second material, apply a “Metal” preset to it.Run a quick render and you can note that this material reflects both the sunlight around it, as well as the other spheres next to it. Notice that if we drag the slider for the reflection glossiness, the material gives a more clear reflection. In this case, a paint material is somewhat reflective, and has a glossiness to it. Notice that when we do this, our material preview changes to show the change to the settings we just made. To start off, let’s apply a preset of “Paint” to the first sphere within the quick settings of Vray.
Notice that when I select a material with the SketchUp eyedropper, the material also gets selected within Vray.
