Texture Map Types
Texture Map Types
Source texture files are converted and compiled in .DDS format by the Resource Compiler (RC). If you do not specify presets for the source file, the Resource Compiler will do the following:
- Files with a file suffix of _ddn or _bump will generate an uncompressed RGBA or U8V8 NormalMap
.DDSfile with height information in the alpha channel. - Files with a non-white (less than 255) alpha channel will generate a DXT3-compressed
.DDSfile. - Files without an alpha channel will generate DXT1 compressed
.DDSfile.
Texture Map Types
| Texture Map | Filename Suffix | Description |
|---|---|---|
| Diffuse map | _diff | Defines the main color for an object. |
| Normal map | _ddn | Defines the direction of normals on an object surface. The RGB normal map stores the normal direction for each pixel in the texture. |
| Normal with Gloss map | _ddna | Achieves physically-correct results. DDNA textures are standard DDN textures with the gloss map stored inside the Alpha channel. |
| Environment map | N/A | Makes an object reflective. The environment map stores the image that is reflected off the object. |
| Displacement map | _displ | Gives more depth and definition to an object when used in tessellations, parallax occlusion mapping (POM), and offset bump mapping (OBM). |
| Detail map | _detail | Adds more detail to a surface. This texture map works like a second material layer and is not affected by the mapping of the object. |
| Emittance Multiplier | N/A | Multiplies the emissive color. |
| Blend (layer) | N/A | Blends multiple textures using an adjustable mask texture and a vertex alpha. |
