In essence both meshes need to be 1) co-located, i.e. In Blender this can be displayed or visualised by activating " Normals" in " Mesh Display" (" View Properties", " N") and selecting any one or combination of " Vertex", " Edge" or " Face" Normals (activating normals on a high-resolution meshes may cause significant performance issues).įor texture baking to work, and RGB Normalised values be properly calculated, it's important to ensure both high and low resolution meshes are correctly prepared beforehand. Specifically for Normal maps the process essentially means translating surface data into a series of " R", " G" and " B" ('red', 'green' and 'blue') colour values, each representing the orientation of an individual face normal.ĭesign note: the " normal" component in " Normal map" refers to " X", " Y" and " Z" coordinate values indicating the orientation of a given 'face'.
Texture baking a mesh to produce a Normal map is usually a 'like-for-like' process in that structural data from a high-resolution mesh is rendered down to an image mapped to a low-resolution facsimile.
which buttons are pressed, when and where. A basic understanding of Blender is useful but not specifically necessary to get the most from the below.ĭesign note: the "Texture Bake" process is much the same in principle as for Blender 2.49 or using Cycles Render although it differs somewhat in process. The following tutorial discusses this process, of using "Blender Render" and the "Texture Bake" sub-system to generate a Normal map from a high-resolution mesh.
