HOW TO CREATE A BUMP MAP IN CHEETAH 3D FULL

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 вЂњbumpвЂќ consists only of a displacement, which takes place along the existing,ДЄnd 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.ДЄlthough the terms Normal Map and Bump Map are often used You will notice that the surface is not really shaped.Д«oth 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,Д«y modifying the shading as if the surface had lots of small angles, rather than being completely flat.Д«ecause it is just modifying the shading of each pixel, Note: Turn on Alpha Is LuminanceВ in the colour balance section under file node when importing graffiti (not under layeredTexture node).Normal Maps and Bump Maps both serve the same purpose: Add a graffiti texture to Alpha in layeredTexture node. Put layered texture node in between the Albedo node and material. Set Scaler Zero Value to 0.5.ДЄdd Graffiti by pressing Tab and typing layeredTextureВ in Hypershade then it creates the node.

Set up type and iterations.Д¬hange Displacement attributes under the Shape tab: Hight, Bounds Padding, Scaler Zero Value. Subdivide at render time: go to Subdivisions under Shape tab in Attribute Editor. In between the shading group and displacement map, we need a DisplacementShader node. Note: Displacement map should be connected to Shading Group (the last node in the shading network), not the material node. Note: Normal map is more realistic than the Bump map.ДЄdd displacement map: displace a physical mesh using the map. Then connect it to Normal Camera (like Bump). Make aINormalMap to connect the normal map to it.

The surface still will be flat after adding bump shader. Note: Bump map does not lift the surface. This will create a node for us to connect our bump map to it. After importing the bump map, go to the shader and find Bump mapping under Geometry. Note: After adding the specular, roughness map, bumpВ and displacement map, turn on ' Alpha is luminance' under colour balance in file node (in Hypershade, when importing the file and setting colour space).ДЄdd bump map to fake depth (like drop shadowing) on the surface-White: more deep, black: less deep. Note: Colour Space: For colour images: sRGB / For 0-1 maps & grayscale images: Raw This helps us to duplicate the Albedo and make other shaders. Place2dTexture: GoВ to these settings to change Repeat UVs (when the texture is too big)В and translate frame options.ДЄfter setting up Place2dTexture for Albedo map: in Hypershade,В select the Albedo map and go to Edit-> Duplicate -> With connections to Network. Put all the maps into Sourceimages folder inside my project folder.
