Design note: A third version of the model is often used, called the ' control cage', this is optional and more to do with work practices as it allows for the creation of both a high and low poly mesh from the same core data. In the image below this is the object marked 'high poly' on the right. The ' high poly 'art' mesh' is a high resolution, high density object built specifically for the purpose of texture baking the structural and geometric detail contained forms the basis upon which normalised data is generated and baked to the image wrapped around the low-poly mesh.

This object should to be optimised relative to its target use and must have at least one Material assigned with a Texture and Image slot be fully UVW unwrapped mapped to the assigned Material/s image/s. The low poly 'game ready' mesh is a low resolution version of the baked model solely for use in-game, in this instance a 'tech' door (shown on the left of the image below marked 'low poly'). Texture Bake Basics for Normal Maps? ^īecause of the way Normal maps are baked, explained below, for this to be performed successfully two prerequisites are needed (rendering baking cannot be done without the following) It is also assumed pre-made assets are available and ready for use as the information below does not discuss how to make high resolution 3D models. To get the most from the following materials its best a basic understanding of Blender be had beforehand being able to move and manipulate objects, change views and select options is necessary. The following is written with Blender 2.49 or below in mind.
