One of the drawbacks of bump mapping is that sometimes, you might not be able to achieve the depth that you’re looking for with a bump map, so you may want to try a displacement map instead. You can adjust the strength of the bump using the “Amount” slider in the maps area of your materials editor. The Vray materials built into Vray have actual bump map images associated with them that help you get a much better result. If you have an actual map of your material, you’ll notice that your result is much better. The best way to do this is to use a texture type that actually has a bump map image associated with it. As you can see, in your rendering, you know have that bump map applied to your white material. Then, go into your maps section of your materials editor and add a bump map material. To do this, start by applying a color texture to your face in SketchUp. To test this, let’s add a bump map to a simple material from SketchUp. It’s basically a shading effect applied to your model. Basically, Vray will use the texture image to determine where it should simulate bumpiness within your model. BUMP MAPPINGīump mapping uses an image in order to simulate bumps on a flat face.
Both of these options are designed to help simulate the bumps and roughness that naturally come with materials in the real world without having to actually model that detail.
In this video, I want to talk about the difference between bump mapping and displacement mapping in Vray for SketchUp. In addition, learn the benefits of both Bump Maps and Displacement maps, and when to use each of them in your Vray Renderings! In today’s video, learn to use Bump Maps and Displacement maps in Vray for SketchUp to create realistic rough surfaces in your renderings.
