Exports

Make the following settings for Front Side and Rear Side in the Exports section:

Base Map	The base map contains the basic information about the image file.
Alpha Map	An alpha Map contains information about transparent areas of a texture. In a 3D software it is required to define the transparent space.
Normal Map	Also referred to as Bump Map. The Normal Map specifies the angle, with which virtual light is reflected over a digital surface. With it the appearance of the texture depth is simulated. The Normal Map is a necessary part of digital textures in a 3D software.
Displacement Map	Also referred to as Height Map. A Displacement Map can artificially generate an additional height of a digital texture. This way, a more realistic appearance of three-dimensional surface structure results within a 3D model.
