now that your bump map is in place, you need to tell v ray how to interpret it. in the bump map rollout, click on the button next to the bump map parameter and select your bump map image. To create a bump map, open the maps tab and click on the bump map button. bump maps are great at adding a lot of low relief detail on low polygon objects, so a one polygon wall could show hundreds of bricks thanks to bump mapping. at its simplest, bump mapping only modifies the surface of a piece of geometry, whereas displacement mapping is actually altering the geometry. A bump map modifies the surface of a geometry.

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 maps are great at adding a lot of low relief detail on low polygon objects, so a one polygon wall could show hundreds of bricks thanks to bump mapping.īump mapping uses an image in order to simulate bumps on a flat face.

Bump mapping uses an image in order to simulate bumps on a flat face. however, bump mapping is a shading effect that only changes the appearance of a surface, while displacement mapping actually modifies the surface. the concept is very similar to bump mapping. Displacement mapping is a technique for adding detail to your scene geometry without having to model it first.

simply apply a bump material to an object to add additional bump or normal map functionality. overview the bump material gives the ability to add bump map and normal map effects when using any material.
