8 On the Output rollout, add a NormalsMap element (see Baked Texture Elements on page 6376). Assign Bump as its target map slot. 9 In the Selected Elements Unique settings group, turn on Output Into Normal Bump. 10 Click Render. 3ds Max renders the Normals map, which stores normals data from the high-res object. As for other kinds of texture baking, it creates a Shell material and applies that to the low-res object, with the Normals map assigned as the bump component. Components of Normal Bump Mapping In the 3ds Max interface, controls for normal bump maps appear in three locations: ■ The Render To Texture dialog Specifically, normal projection controls are found on the Objects To Bake rollout on page 6401 and the Output rollout on page 6406. ■ The Projection modifier on page 1628 You can apply a Projection modifier yourself, or let Render To Texture do so automatically. ■ The Normal Bump map type on page 6033 Render To Texture creates this automatically if you turn on Output Into Normal Bump (step 9, above). Viewing Normal Bump Maps If your display driver uses DirectX 8, you can view normal maps in viewports by using the Metal Bump shader on page 5761. If your graphics driver is DirectX 9, you can view normal maps in any shaded viewport. See Direct3D Driver Setup Dialog on page 7800. If your display driver is Software or OpenGL, you can't view normal maps in viewports. However, you can still render them and use normal mapping in renderings. Normal Projection with Sub-Object Selections You can associate different sub-object selections with different high-resolution geometry. See Reference Geometry Rollout (Projection Modifier) on page 1633. Creating and Using Normal Bump Maps | 6385
