u32 mat_tag
|
Tag indicating Mat. Set the following flag.
TAG_MAT 0x000a0100
|
|
u32 this_mat_index
|
Index number of this Mat area.
|
|
u32 mat_size
|
Size of this Mat area
|
|
u32 mat_name_index
|

|
|
u32 mat_type
|
Material in NIFF has three types: mat_shade_type, mat_color_type, and mat_alpha_type.
mat_shade_type is the field primaly to specify the setting for shooting. mat_color_type is the field to specify the setting of color value.
mat_alpha_typeis the field to specify the setting for Alpha value. Also, mat_color_type and mat_alpha_type have two fields each for application on N64.
You can specify how to refer to flags for Color setting and Alpha setting at mat_type field for customaization. The following flags are already specified at present.
MAT_TYPE_NIFF 0x00000000
MAT_TYPE_N64 0x01010101
MAT_TYPE_NIFF sets the conbination of color value and that of Alpha value respectively using colors to be set in the NIFF format. Flags set in these fields for mat_color_type* or mat_alpha_type* specify the exclusive flag for MAT_TYPE_N.
MAT_TYPE_N64 can use flags specified in mat_color type* and mat_alpha_type* to be able to specify all setting in color combiner of NINTENDO64. However, in case of the usage of color value which is not set in NIFF, you need to allocate colors to several user_flag on convertor to convert from NIFF to N64 in advance.
For details, please see Chapter 4, "Note for material type setting."

u32 mat_shade_type
|
This field primarily specifies the shading attributes of materials. The following flags are currently defined.
MAT_SHADE_LIGHT_OFF 0x00000000
MAT_SHADE_LIGHT_LOCAL 0x00000001
MAT_SHADE_LIGHT_GLOBAL 0x00000002
MAT_SHADE_FLAT 0x00000000
MAT_SHADE_SMOOTH 0x00000010
MAT_SHADE_USE_HILIGHT 0x00000100
MAT_SHADE_USE_REFLECT 0x00000200
The MAT_SHADE_LIGHT_* flag specifies the effect of light on materials.
If MAT_SHADE_LIGHT_OFF is set,the lighting process specified is not performed.
If MAT_SHADE_LIGHT_LOCAL is set, the Light in LightList that has the index specified by the local_light_index of this Mat area is used.
MAT_SHADE_LIGHT_GLOBAL is used, the Light that links to Scene is used.
MAT_SHADE_FLAT and MAT_SHADE_SMOOTH are flags that specify shading information of triangles.
If MAT_SHADE_FLAT is set, triangles are drawn using the spefified material.
If MAT_SHADE_SMOOTH is set, triangles are drawn using the specified material with color graduated between vertices.
MAT_SHADE_USE_HILIGHT specifies the use of highlight texture mapping.
MAT_SHADE_USE_REFLECT specifies the use of reflection texture mapping.
The MAT_SHADE_LIGHT_* flag must always be specified and only one MAT_SHADE_LIGHT_* setting can be specified.
Either MAT_SHADE_FLAT or MAT_SHADE_SMOOTH must always be specified. The use of MAT_SHADE_USE_HILIGHT and MAT_SHADE_USE_REFLECT is optional. Only one or the other may be specified.
