Materials

Materials hold data about how certain parts of a model should render. They hold the textures, color data, shader flags, and blend flags.

Textures

Arcade Textures

Project DIVA games that follow Arcade's structure (Arcade, Dreamy Theater/2nd/Extend, Arcade Future Tone, Future Tone, Mega Mix/+) support the following textures:

Texture Type	Use	Example	Flag
Color	The base color of the model (Also known as "Diffuse" or "Albedo" textures). The Alpha channel can be used for the transparency of the model. If second Color map is present, it is treated as a lightmap.	[insert]	Color, ColorL1
Normal	Normal Map for baked details	[insert]	Normal, NormalAlt
Specular	Controls the Specular reflection color and intensity, with the Alpha channel controlling Environment intensity	[insert]	Specular
Translucency	Controls blending of the skin color in the TIGHTS shader. (Unused on the HAIR shader)	[insert]	Translucency
Transparency	Controls the transparency of the model	[insert]	Transparency
EnvironmentCube	Cubemap used for reflective surfaces	[insert]	Environment

F Textures

Project DIVA games that follow F's structure (F, F2nd, X) support the following textures:

Texture Type	Use	Example	Flag
Color	The base color of the model (Also known as "Diffuse" or "Albedo" textures). The Alpha channel can be used for the transparency of the model. If second Color map is present on the BLINN shader, it is treated as a lightmap. If the texture is RGB8 and has the 0x000500E0 Sampler flag, it is treated as a Toon Curve texture. (Note: the toon curve texture has 4 lines of data, the top line is unused, the 2nd line controls the fresnel, the 3rd line controls the specular, and the 4th line controls the diffuse)	[insert]	Color, ColorL1
Specular	Controls the Specular reflection color and intensity	[insert]	Specular
EnvironmentCube	Cubemap used for reflective surfaces. Only supported on the BLINN shader	[insert]	Environment

X (Ps4) Textures

Project DIVA X on the Playstation 4 features upgraded graphics, and has support for different textures as such:

Texture Type	Use	Example	Flag
Color	The base color of the model (Also known as "Diffuse" or "Albedo" textures). The Alpha channel can be used for the transparency of the model.	[insert]	Color, ColorL1
Normal	Normal Map for baked details. The alpha channel controls the Ambient Occlusion of the model.	[insert]	Normal, NormalAlt
Specular	Material texture, where: The Red channel is roughness, The Green channel is fresnel reflectance (and the material is treated as metal if the value is over 0.999), The Blue channel controls where Self-Shadowing should take place, The Alpha channel controls the brightness of the fresnel effect of the model.	[insert]	Specular
Height	Controls the emmision of the model, with the Alpha channel acting as a Specular map	[insert]
Translucency	Toon Curve texture, with 4 lines of data: The top line is unused, The 2nd line controls the fresnel ramp The 3rd line controls the specular ramp The 4th line controls the diffuse ramp	[insert]
Transparency	Cubemap used for reflective surfaces	[insert]	Environment
(not indexed)	Lightmap for baked lighting (Used in the OBJM_H shader)	[insert]

Blend Flags

Blend flags are material settings that specifically affect how a model is drawn.

Flag	Input	Use
Alpha texture	True, False	Enables the transparency of a model to be driven by the Alpha channel of the color or transparency texture.
Alpha material	True, False	Enables the transparency of a model to be driven by the Alpha value of the material.
Punch through	True, False	Discards alpha values below 0.5, resulting in sharper transparency
Double sided	True, False	Disables Backface Culling when true
Normal direction light	True, False	Unused(?)
Source blend factor	String	Used to determine blending behaviour
Destination blend factor	String	Used to determine blending behaviour
Blend Operation	Value	Unused(?)
Z bias	0-15	Unused
Ignore fog	True, False	Material will not be affected by fog if true
