For each duplicate layer, apply the NormalMapFilter with a filter type of 3Г—3, 7Г—7 and 9Г—9 respectively.

You donвЂ™t need to worry about all the settings to create a simple normal map. Just open up your Bump map in Photoshop and apply this filter. After installation youвЂ™ll find it as a Filter > Nvidia Tools > NormalMapFilter.

If you already have bump maps, you can use them to create a normal map using the free Nvidia plugin for Photoshop. So wherever the normal changes, the color changes while the flat surface is purple. In case youвЂ™re wondering, вЂnormalвЂ™ is the technical name given to the direction which is perpendicular to the surface. The color change tells the renderer the anglesВ of the normals of the surface. Normal-maps are usually purple, with cyan and pink hues. Quite simply, you can view from different directions and move lights, and youвЂ™ll get realistic 3d details. This tricks the ray trace rendering into believing itвЂ™s a real geometry and casts shadows accordingly. Normal-maps look more realistic than bump because they carry the complete 3 dimensional data, and not just height alone. Where bump maps add the illusion of height to details, normal-maps go much beyond that. There is also the option of bump maps, but these are mostly obsolete nowadays. When you want to add fine detail to meshes, you can either use real geometry or normal-maps. You can then apply a map in the same way that we applied the bump map material.Learn to create Normal Map with FREE NVIDIA plugin and shave off rendering time. Once youвЂ™ve grouped your geometry, youвЂ™re then going to go in and enable displacement mapping in the material settings. Larger edge length = faster render times, lower quality However, youвЂ™ll also notice that displacement maps take SIGNIFICANTLY more time to render that bump maps, so you may not want to use them unless youвЂ™re trying to simulate fine detail. Notice that the materials themselves simulate the roughness of the material much more accurately with a displacement map. This will also work with your built-in Vray materials, just make sure to go in and apply your bump map to your displacement map. You can adjust how strong this effect is by adjusting the amount setting within Vray. Notice that when you run your render now, Vray is actually changing the location of the geometry within your face, rather than just simulating a bump with light. I was not able to get it working with raw geometry. So the first thing to note when working with displacement mapping (at least in my experience), is that it really works best with materials applied to groups of geometry. What a displacement map does is actually move your geometry within your render to give you an accurate simulation of a rough material. One of the drawbacks of bump mapping is that sometimes, you might not be able to achieve the depth that youвЂ™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 вЂњAmountвЂќ 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, youвЂ™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, letвЂ™s add a bump map to a simple material from SketchUp. ItвЂ™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 MAPPINGД«ump 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 todayвЂ™s video, learn to use Bump Maps and Displacement maps in Vray for SketchUp to create realistic rough surfaces in your renderings.
