= Material Textures Influence =

Not only can textures affect the color of a material, they can also affect many of the other properties of a material. The different aspects of a material that a texture influences are controlled in the {{Literal|Influence}} panel.
{{note|Note|Texture options for {{Literal|Surface}} and {{Literal|Wire}} materials and in some cases also for {{Literal|Volume}} and {{Literal|Halo}} materials.}}
== Surface and Wire materials ==
[[File:25-Manual-Textures-Influence-Surface.png|thumb|308px|Texture {{Literal|Influence}} panel for a {{Literal|Surface}} material]]

==== Diffuse ====
; {{Literal|Intensity}}: Amount texture affects affects diffuse reflectivity
; {{Literal|Color}}: Amount texture affect the basic color or RGB value of the material
; {{Literal|Alpha}}: Influences the opacity of the material. See [[Doc:2.5/Tutorials/Textures/Use Alpha for Object Transparency|Use Alpha for Object Transparency]]. Also use {{Literal|Z Transparency}} for light and if combining multiple channels.
; {{Literal|Translucency}}: Influences the Translucency amount.

==== Specular ====
; {{Literal|Intensity}}: Amount texture affect specular reflectivity
; {{Literal|Color}}: Influences the {{Literal|Specular}} color, the color of the reflections created by the lamps on a glossy material.
; {{Literal|Hardness}}: Influences the specular hardness amount. A DVar of 1 is equivalent to a Hardness of 130, a DVar of 0.5 is equivalent to a Hardness of 65.

==== Shading ====
; {{Literal|Ambient}}: Influences the amount of Ambient light the material receives.
; {{Literal|Emit}}: Influences the amount of light Emitted by the material.
; {{Literal|Mirror}}: Influences the mirror color. This works with environment maps and raytraced reflection.
; {{Literal|Ray Mirror}}: Influences the strength of raytraced mirror reflection.

==== Geometry ====
; {{Literal|Normal}}: Commonly called bump mapping, this alters the direction of the surface normal. This is used to fake surface imperfections or unevenness via bump mapping, or to create reliefs.
; {{Literal|Warp}}: {{Literal|Warp}} allows textures to influence/distort the texture coordinates of a next texture channel. The distortion remains active over all subsequent channels, until a new Warp has been set. Setting the factor at zero cancels out the effect.
; {{Literal|Displace}}: Influences the Displacement of vertices, for using [[Doc:2.6/Manual/Textures/Influence/Material/Displacement|Displacement Maps]].

=== Other Controls ===

;{{Literal|Blend}}
:Blending operation to perform. See [[Doc:2.6/Manual/Textures/Influence/Material/Blending_Modes|Texture Blending Modes]] for details.
;{{Literal|RGB to intensity}}
:With this option enabled, an RGB texture (affects color) is used as an intensity texture (affects a value).
;{{Literal|Blend Color}}
:If the texture is mapped to Col, what color is blended in according to the intensity of the texture? Click on the swatch or set the RGB sliders.
;{{Literal|Negative}}
:The effect of the Texture is negated. Normally white means on, black means off, {{Literal|Negative}} reverses that.
;{{Literal|Stencil}}
:The active texture is used as a mask for all following textures. This is useful for semitransparent textures and "Dirt Maps". Black sets the pixel to "untexturable". The {{Literal|Stencil}} mode works similar to a layer mask in a 2D program. The effect of a stencil texture can not be overridden, only extended. You need an intensity map as input.
;{{Literal|DVar}}
:Destination Value (not for RGB). The value with which the Intensity texture blends with the current value. Two examples:

*The {{Literal|Emit}} value is normally 0. With a texture mapped to {{Literal|Emit}} you will get maximal effect, because {{Literal|DVar}} is 1 by default. If you set {{Literal|DVar}} to 0 no texture will have any effect.

*If you want transparent material, and use a texture mapped to {{Literal|Alpha}}, nothing happens with the default settings, because the {{Literal|Alpha}} value in the {{Literal|Material}} panel is 1. So you have to set {{Literal|DVar}} to 0 to get transparent material (and of course {{Literal|Z Transparency}} also). This is a common problem for beginners. Or do it the other way round - set {{Literal|Alpha}} to 0 and leave {{Literal|Dvar}} on 1. Of course the texture is used inverted then.

;{{Literal|Bump Mapping}}: Settings for bump mapping.
:;{{Literal|Method}}
:{{Literal|Best Quality}}, {{Literal|Default}}, {{Literal|Compatible}}, {{Literal|Original}}
:;{{Literal|Space}}: {{Literal|Texture Space}}, {{Literal|Object Space}}, {{Literal|View Space}}
{{Clr}}

== Volume materials ==

[[File:25-Manual-Textures-Influence-Volume.png|thumb|308px|Texture {{Literal|Influence}} panel for {{Literal|Volume}} material]]

Special texture options for {{Literal|Volume}} materials
; {{Literal|Density}}: Causes the texture to affect the volume's density.
; {{Literal|Emission}}: Causes the texture to affect the volume's emission.
; {{Literal|Scattering}}: Amount the texture affects scattering.
; {{Literal|Reflection}}: Amount the texture affects brightness of out-scattered light
; {{Literal|Emission Color}}: Amount the texture affects emission color.
; {{Literal|Transmission}}: Amount the texture affects result color after light has been scattered/absorbed.
; {{Literal|Reflection Color}}: Amount the texture affects color of out-scattered light.

== Halo materials ==

[[File:25-Manual-Textures-Influence-Halo.png|thumb|308px|Texture {{Literal|Influence}} panel for a {{Literal|Halo}} material]]
Special texture options for {{Literal|Halo}} materials
; {{Literal|Size}}: Amount the texture affects ray mirror.
; {{Literal|Hardness}}: Amount the texture affects hardness.
; {{Literal|Add}}: Amount the texture affects translucency.
