You can change the amount for altering the strength of the effect and get more definition.
Now plug this map into a VRayNormalMap and into your material bump slot.We now have a composite normal map with sharp and smooth fading detail.Now, by using the opacity setting for layers, blend all of these 3 maps.For each duplicate layer, apply the NormalMapFilter with a filter type of 3×3, 7×7 and 9×9 respectively.You don’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 you’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 you’re wondering, ‘normal’ is the technical name given to the direction which is perpendicular to the surface.
The color change tells the renderer the angles 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 you’ll get realistic 3d details. This tricks the ray trace rendering into believing it’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. Learn to create Normal Map with FREE NVIDIA plugin and shave off rendering time.
