In addition to the [[LuxCoreRender_Textures_Blender| Blender Textures]], LuxCoreRender support a number of its own procedural textures. These also include special textures for mixing or altering other textures.

==Procedural Types==

===Add===
*Output value: float or color
[[Image:Texture_add.jpg‎|frame|left|Add texture using a blue and an orange texture]] 
The Add texture mixes two textures by adding the color/grey scale values together. For example, if the same area in both textures uses the color value 0.4 (grey), the resulting color will be 0.8 (white) in that area.

===Band===
*Output value: float, color or fresnel
Band allows for a gradient to be generated using "stops" which can be colors/floats or textures. The "mix amount" value defines where on the gradient the texture's final output value will be taken. You can use blender_blend from 0-1 on the mix amount to output the entire gradient.

To understand this texture, it may help to think of the regular mix texture as a gradient editor as well. Mix would be like a gradient editor that can only have 2 stops, which are stuck at either end of the gradient. Band, however, allows however many stops you want, placed wherever you want. Either way, you sample a single point on the gradient. So texturing mix amounts allows you to change which point is sampled depending on the location on the texture.

===Bilerp===
*Output value: float, color or fresnel
[[Image:Procedural_bilerp.png|frame|left|''bilerp'' texture using ''uv'' and ''spherical'' mapping]] 
The bilerp texture takes four colors as input and interpolates the colors in between. It can use uv, planar, cylindrical and spherical mapping.

===Brick===
*Output value: float or color
[[Image:Bricktest.jpg|frame|left|Examples of brick textures]]
 
The brick texture generates a 3D projection of a tiled brick-and-mortar pattern. 
The parameters can be changed to simulate a variety of common brick and tile installations that have a repeating pattern.
 
''Note:'' it does not cross corners or handle curved surfaces in a realistic way.

'''Parameters'''

*'''Bond type''': choice of 7 patterns: chain link, basket, herringbone, english, flemish, stacked, running
** 5 wall patterns
*** chain link, english, flemish, stacked, running
*** show on the object's x-by-z faces by default (results dependent on object or global selected in Texture Transform coordinates).
*** use Texture Transform, Object Coords, Rotate to move the texture to the desired object face
** 3 floor patterns
*** herringbone, basket, stacked
*** show on the object's x-by-y faces by default (results dependent on object or global selected in Texture Transform coordinates).
*** use Texture Transform, Object Coords, Rotate to move the texture to the desired object face
*'''Width''': length of brick (longest edge of brick by default)
*'''Height''': row size of brick (stacking height per brick)
*'''Depth''': size of brick face that is covered when stacked (buried inside the surface)
*'''Mortar size''': width of mortar line between bricks
*'''Bevel''': ?
*'''brickrun''': amount of linear offset down the row between adjacent rows
** only works for running, english, flemish
** for the correct pattern, flemish brickrun must be 0.75
*'''bricktex''': color or texture of exposed brick face
*'''brickmodtex''': modulation texture of brick face--sampled randomly for each brick to pick a color that will modify bricktex--use it to break up color uniformity by creating a field of bricks with varying shades or colors
*'''mortartex''': color or texture of exposed mortar lines

===Checkerboard===
*Output value: float or color
[[Image:Procedural_checkerboard.png|frame|left|2d and 3d ''checkerboard'' texture]] 

This texture generates a two- or three-dimensional checkerboard pattern.

'''Parameters'''

*'''2d/3d''': switches between the two- and threedimensional patterns
*'''closedform/supersample''': anti aliasing algorithms for the 2d pattern
*'''uv''': base the pattern on the object's uv texture mapping
*'''cylindrical''': use a cylindrical projection (2d pattern)
*'''spherical''': use a spherical projection (2d pattern)
*'''planar''': use a planar projection (2d pattern)
*'''Ud/Vd''': offset values for the planar projection

===Cloud===
*Output value: float only
This texture creates a 3D volumetric cloud.

'''Parameters'''

*'''radius''': overall cloud radius inside the base cube
*'''noisescale''': strength of the noise
*'''turbulence''': size of the noise displacement
*'''sharpness''': noise sharpness - increase for more spikey appearance
*'''noiseoffset''': offset value for noise pattern
*'''numspheres''': count of spheres for cumulus cloud generation
*'''octaves''': the range of noise frequencies - higher values create more *'''omega''': the amount of noise per octave
*'''variability''': amount of extra noise
*'''baseflatness''': the strength of the flattening effect on the bottom of the cloud
*'''spheresize''': size of spheres for cumulus cloud generation

===Dots===
[[Image:Procedural_dots.png|frame|left|''dots'' texture]] 
*Output value: float only
This texture creates a grid of dots, each of which has a 50% chance of being displayed.
'''Parameters'''

*'''uv''': base the pattern on the object's uv texture mapping
*'''cylindrical''': use a cylindrical projection
*'''spherical''': use a spherical projection
*'''planar''': use a planar projection
*'''ud/vd''': offset values for the planar projection

===FBm===
[[Image:Procedural_FBm.png|frame|left|''fbm'' texture]] 
*Output value: float only
The FBm (fractal Brownian motion) texture generates fractal noise, which is very suitable for use as a bump map.
'''Parameters'''

*'''roughness''': the noise roughness - low values generate smooth shapes, higher values add detail
*'''octaves''': the range of noise frequencies - higher values create more detailed patterns

===Harlequin===
[[Image:Procedural_harlequin.png|frame|left|''harlequin'' texture]] 
*Output value: color only
This texture assigns a color to each face, which can be useful for checking mesh subdivisions.

===Marble===
[[Image:Procedural_marble.png|frame|left|''marble'' texture]] 
*Output value: color only
The marble texture generates a marble pattern by distorting a layer pattern.

'''Parameters'''

*'''octaves''': the range of noise frequencies
*'''roughness''': the amount of noise
*'''noisescale''': the scale of the noise
*'''variation''': additional variation in the pattern by offsetting through the marble layers

===Mix===
[[Image:Texture_mix.png|frame|left|''mix'' texture, mixing a checkerboard with a solid red color]] 
*Output value: float, color or fresnel
The mix texture mixes textures by taking the average of their color values. The proportion between the two source textures can be defined by the user.



===Scale===
[[Image:Texture_scale.png|frame|left|''scale'' texture, scaling a checkerboard with a solid red color]] 
*Output value: float or color
The scale texture mixes textures by multiplying their color values, where black is zero and white is one.

===UV===
[[Image:Procedural_uv.png|frame|left|''uv'' texture]] 
*Output value: color only
The UV procedural texture is intended to clearly display UV mapping. A red gradient is used for the U direction, while a green gradient indicates the V direction.

===Windy===
[[Image:Procedural_windy.png|frame|left|''windy waves'' texture]] 
*Output value: float only
The windy (or windy waves) texture is intended as a bump map or displacement map for waves. It is based on the FBm material and does not have any adjustable parameters.

===Wrinkled===
[[Image:Procedural_wrinkled.png|frame|left|''wrinkled'' texture]] 
*Output value: float only
The wrinkled texture generates turbulence noise, which is very suitable for use as a bump map.
'''Parameters'''

*'''roughness''': the noise roughness - low values generate smooth shapes, higher values add detail
*'''octaves''': the range of noise frequencies - higher values create more detailed patterns
