In other words, Blender neds todo know where it supposed todo bake (or write, Paint) the coloured normals, what áreas of the texture image should have baked normals and what áreas shouldnt.įor this todo happen the Low poly Mesh must have a functional UVW map with materiales and textures assigned. Preparing the models, what neds todo be done beforehand?īecause the high resolution object is efectively being baked todo the Low resolution one, there neds todo be a bien for the baking process todo understand what it supposed todo be doing in relation todo both objects. The High Poly versión of the dor is shown on the right of the image below.ĭesign note : a third versión of the model is often used, called the control Cage, this is optional and more todo do with work practices (#).įigure 1: wire-frame view of the required assets, in this case a tech(ish) dorway. The High Poly art Mesh Will be used todo provide the geometric detail that baked todo the image applied over the game Mesh.

The Low poly game Mesh is the actual Mesh that Will eventually be used in game, in this instance a tech dor shown on the left of the image below marked Low poly, this should be optimised as well as posible (as few Polygons as necessary for its target use), and must be UVW mapped and textured. To successfully bake Normal Maps using Blender 3d a number of Items are required before anything can be done. It a los assumed there are assets available and ready for use - The información below wont discuss how todo make high resolution 3d models. The following tutorial discusses the creation of Normal Maps in the context of renderbump, that is, using Blender 3d own internal ability todo bake the topology and Physical characteristics of a high resolution, highly detailed 3d object todo an image called a Normal Map (#).Īn Understanding of Blender basic is required, so being able todo move objects, change views and manipulate objects Will be necessary. There are generally regarded todo be two ways todo generate Normal Maps from 3d content, renderbump and renderbumpflat.
