To create a normal map
1 Select Lighting/Shading > Transfer Maps.
The Transfer Maps window appears.
The Transfer Maps window lets you create various textures based on
mappings from polygon models. First you need to assign the source and
target meshes for the transfer.
2 In the Outliner, select lo_res_toad.
3 In the Transfer Maps window, in the Target Meshes section, click Add
Selected.
4 In the Outliner, select hi_res_toad.
5 In the Transfer Maps window, in the Source Meshes section, click Add
Selected.
Next you need to set the Search Envelope.
The Search Envelope represents the volume of the target geometry to consider
for the texture. Whatever part of the source mesh between the Search Envelope
and the target mesh is mapped to a texture.
Generally you want the Search Envelope to encompass your entire source
mesh so you dont miss any detail.
To set the Search Envelope
1 In the Transfer Maps window, set Display to Envelope.
The low resolution toad is replaced by a translucent red mesh.
This red mesh represents the Search Envelope.
2 Drag the slider under Search envelope (%) to the right.
The red mesh grows.
Drag the slider so that the red mesh barely encompasses all of the high
resolution mesh without leaving any white spots (excluding the eyes).
You can also enter a value in the box next to the slider. In this case, a
value of 4.3 yields just enough coverage around the two meshes.
