Texture is a container section used in DFF files as child of a material section or an Material Effects PLG section. The section itself does not store any data at all. All additional information get stored inside a struct section which directly follows this one as a child. A texture section is used to store the sampler state of a texture.
Structure
The structure stores filtering and uv-addressing information for the texture.
1byte Texture filtering (Texture filtering modes) 4bit U-addressing 4bit V-addressing 1bit Does texture use mip levels 15bits padding
Example C structure (UInt32 is a 4 byte unsigned integer type)
struct
{
// Filtering mode
UInt32 filtering : 8;
// Addressing modes for u, v
UInt32 u : 4;
UInt32 v : 4;
UInt32 mipmaps : 1;
};Texture filtering modes
0 - FILTERNAFILTERMODE (filtering is disabled) 1 - FILTERNEAREST (Point sampled) 2 - FILTERLINEAR (Bilinear) 3 - FILTERMIPNEAREST (Point sampled per pixel mip map) 4 - FILTERMIPLINEAR (Bilinear per pixel mipmap) 5 - FILTERLINEARMIPNEAREST (MipMap interp point sampled) 6 - FILTERLINEARMIPLINEAR (Trilinear)
Texture addressing modes
0 - TEXTUREADDRESSNATEXTUREADDRESS (no tiling) 1 - TEXTUREADDRESSWRAP (tile in U or V direction) 2 - TEXTUREADDRESSMIRROR (mirror in U or V direction) 3 - TEXTUREADDRESSCLAMP 4 - TEXTUREADDRESSBORDER
Child sections
There are always child sections which appear in the order they are listed here.
