Settings
Type – Specifies which type to use for the Cellular texture. The choices are Dots, Chips, Cells, Chess Cells, or Plasma.
Background Color – Controls the color of the background of the Cellular procedural texture.
Center Color – Controls the color of the center of the cells.
Edge Color – Controls the color of the edges of the cells in the Cellular procedural texture.
Size – Controls the size of the Cellular procedural texture. For more details, please see the Size examples below.
Spread – Controls the spread of the procedural Cellular texture. For more details, please see the Spread examples below.
Density – Controls the Density of the Cellular texture. For more details, please see the Density examples below.
Low – Controls the low threshold (background color). For more details, please see the Low examples below.
Middle – Controls the middle threshold (edge color). For more details, please see the Middle examples below.
High – Controls the high threshold (center color). For more details, please see the High examples below.
Fractal – Enables the addition of fractal generation. Only available with Dots and Chips Types.
Fractal Iterations – Controls the number of fractal iterations. For more details, please see the Fractal Iterations examples below.
Fractal Roughness – Controls the roughness of the fractal. A value of 0.0 is very rough and a value of 1.0 is very smooth, which negates the fractal. For more details, please see the Fractal Roughness examples below.
Color Tweaks
Default Color – Specifies the color when there are no valid UVW coordinates.
Mult – Specifies a strength multiplier for the texture color.
Offset – Color corrects the texture by adding the RGB color values specified here to the RGB color values in the texture.
Invert – When enabled, inverts the resulting texture color.
Alpha Tweaks
Source – Specifies where the alpha channel is drawn from:
Alpha – Alpha channel is drawn from the texture.
Color – Alpha is generated from pixel intensity.
Opaque – Alpha channel is fully opaque.
Use – Differentiates between textures exported from different applications. You can choose between Color Intensity (3ds Max) and Color Luminance (Maya).
Mult – Specifies a multiplier for the texture alpha.
Offset – Specifies an additional offset for the texture alpha.
Invert – When enabled and Invert from Color Tweaks is also on, the resulting texture alpha is inverted as well.

Rotate Frame – Rotates the frame after applying UV noise.
Rotate UV – Rotates the UVs after mirroring.
Offset U – Offset added to U before mirroring (after wrap, coverage, clamp).
Offset V – Offset added to V before mirroring (after wrap, coverage, clamp).
Noise U – Noise magnitude multiplier in U direction.
Nose V – Noise magnitude multiplier in V direction.
Mirror U – When enabled, every other tile outside the [0;1] range is mirrored in U.
Mirror V – When enabled, every other tile outside the [0;1] range is mirrored in V.
Wrap U – When enabled, U values outside the [0;1] range wrap back to [0;1].
Wrap V – When enabled, V values outside the [0;1] range wrap back to [0;1].
Stagger – When enabled, tiles in the V direction add +0.5 to the U value for a 'staggering' effect.
Type – Specifies the type of projection mapping to use from the following:
None
Planar
Spherical
Cylindrical
Ball
Cubic
Tri-Planar
Perspective
Projection Camera – Selects a camera.
Projection Camera (LOP) – Same as Projection Camera parameter but for use in the LOP context.
Fit Fill – Specifies how the projection is fitted.
Fit Fill – Fitted to fill the space.
Horizontal – Fitted horizontally.
Vertical – Fitted vertically.
Fit Type – Specifies the type of fitting to use:
None
Match Camera Film Gate
Match Camera Resolution
U / V Angle – Specifies the U / V mapping angle.
Film Gate W / H – Specifies the width / height of the film gate.
Hide Backface – Determines whether to project on back faces of polygons.
Hide Occluded – Determines whether to project on occluded points when using the Perspective Type.
Object Space – When enabled, the projection is applied in the object space of the currently shaded geometry.
Mapping Type – Specifies the type and shape of the texture from the following: Spherical, Angular, Cubic, Mirror Ball, Screen, Spherical (3ds Max), Cylindrical (3ds Max), Shrink Wrap (3ds Max), and Spherical (V-Ray).
