When using a Normal map, map the texture to Normal.When using a Bump map, map the texture to Normal and enable No RGB.
Special considerations for Bump and Normal Maps is: Mapping is the process of applying a texture to the low-poly mesh.įor more information on applying a texture to a mesh’s material. Modeling feature can be used to good effect here). This may be replaced with a single plane, oriented in the same direction as the detailed ear mesh. For example,Ī highly detailed ear may have 1000 faces in the high-poly model. The same or similar faces should exist that reflect the model. Modeling a low-poly using Blender’s Mesh editing tools. Use the Render Bake feature in Blender to accomplish this. The similar object is identical to the high-poly mesh except with less vertices. The more ridges and details (knobs, creases, protrusions) you put in, the more detailed your map will be.īaking a map, simply put, is to take the detail of a high polygon mesh, and apply it to a similar object. How much detail you put in is totally up to you.

Map the map to the low-poly model using a common coordinate system.Ĭonsult the Modeling section for how to model a highly detailed model using the Mesh tools.Model a highly detailed (“hi-poly”) model.The steps involved in making and using Bump and Normal Maps is: The latter convention is used in “Doom 3” for example.

In Blender we store a full blue range, although some other implementations also map blue colors (128 - 255) to Since normals all point towards a viewer, negative Z values are not stored (they would be invisible anyway). Normal maps in Blender store a normal as follows: Often from higher resolution geometry than the geometry you are applying the map to. Normal maps usually have to be generated in some way, The drawbacks to normal maps are that unlike bump maps, which can easily be painted by hand, They can simulate that pixel being moved at any direction, in an arbitrary way.
They are much more accurate, as rather than only simulating the pixel being away from the face along a line,
These are images that store a direction, the direction of normals directly in the RGB values of an image. You may either use grayscale pictures or the intensity values of an RGB texture (including images). (The “bump” consists only of a displacement, which takes place along the existing,Īnd unchanged, normal vector of the face). The pixels seem to be moved by the required distance in the direction of the face normals. Bump maps These are textures that store an intensity, the relative height of pixels from the viewpoint of the camera. Synonymously, there are certain differences. (the direction pointing perpendicular from a face), which influences how a pixel is shaded.Īlthough the terms Normal Map and Bump Map are often used You will notice that the surface is not really shaped.īoth Bump Maps and Normal Maps work by modifying the normal angle If the camera angle is too flat to the surface, This will not cast any shadows and will not obstruct other objects. They simulate the impression of a detailed 3D surface,īy modifying the shading as if the surface had lots of small angles, rather than being completely flat.īecause it is just modifying the shading of each pixel, Normal Maps and Bump Maps both serve the same purpose:
