Distribute Workspace

From Garibaldi Express
Jump to: navigation, search

Quickly specify where and how much hair to add to your character with seamlessly even follicle distribution.

Add hair colouring with base and tip colour texture maps. Add controllable root darkening and hair strand colour salt and peppering for that professional quality.

Settings

The following describes the settings for hair strand follicle distribution, hair strand colourings and width settings and viewport preview settings for the 'Garibaldi Express' distribution workspace.

Distribution

Specifies how many and where hair strand follicles are distributed over the characters surface geometry. Uses a high quality pseudo-random point distribution algorithm to produce a even density of follicles throughout the characters geometry surfaces. The pseudo-random distribution progressively adds more follicles as the distribution amount increases, rest lting a predicable even distributed follicles.


Distrubution Settings.


Amount

Specifies how many hair follicles are created on average on every square centimetre of a characters geometry surface.

Amount = 10.0
Amount = 50.0
Amount = 140.0

The texture control setting will multiple the follicle amount. A texture control is required for the follicle distribution to proceed.

Amount = 200.0 with control texture
The control texture

Seed

The random generator seed for the follicle distribution. Editing this setting will cause all follicles to shift to different positions on the character geometry surface while retaining the same practicable distribution.

Seed = 0
Seed = 1
Seed = 2

Width

Settings used to specify the hair stand widths during rendering.


Width Settings.


Base

The width the hair strands will be at the base. Toward the tip of the hair strand the base width will blend with the tip settings value. Half way up the hair strand the width value will be half way between the Base and Tip settings value.

Base = 0.0, Tip = 0.01
Base = 0.025, Tip = 0.01
Base = 0.1, Tip = 0.01

Tip

The width the hair strands will be at the base. Toward the tip of the hair strand the base width will blend with the tip settings value. Half way up the hair strand the width value will be half way between the Base and Tip settings value.

Base = 0.01, Tip = 0.0
Base = 0.01, Tip = 0.025
Base = 0.01, Tip = 0.1

Colour

The colour the hair strand will use as the basis for there colour when rendering. Note that the Colour Salting/Peppering settings and the Garibaldi nodes material shader can be set to override this colour in certain ways.

Colour Settings.
Base = Red, Tip = Red
Base = Blue, Tip = Red
Base = Blue, Tip = Blue

Base

The colour the hair strands will be at the base during rendering. Toggling the 'Use Preview Hair Colour' setting will preview the colour settings in the Garibaldi Editor preview viewport. Toward the tip of the hair strand the colour base setting value will blend with the tip settings value. At the mid point specified by the blend bias the hair strand colour value will be half way between the Base and Tip settings value. Clicking the colour preview rectangle will display the Windows/Macintosh colour picker dialog box.

An optional colour control texture setting will override the base colour value setting.

Base = Control Texture, Tip = Red
The control texture

Tip

The colour the hair strands will be at the tip during rendering. Toggling the 'Use Preview Hair Colour' setting will preview the colour settings in the Garibaldi Editor preview viewport. Toward the tip of the hair strand the colour base setting value will blend with the tip settings value. At the mid point specified by the blend bias the hair strand colour value will be half way between the Base and Tip settings value. Clicking the colour preview rectangle will display the Windows/Macintosh colour picker dialog box.

An optional colour control texture setting will override the tip colour value setting.

Base = Blue, Tip = Control Texture
The control texture

Root Dark

A fractional value setting of how much to darken the base hair stand colour by. A value of 1.0 will cause the base colour to become black. A value of 0.0 will not change the base colour.

Root Dark = 0.0
Root Dark = 0.5
Root Dark = 1.0

Blend Bias

This fractional value will set how the base and tip colour values blend along the hair strands length. The value specifies the where along the hair strand the tip and base values will be evenly blended. As the setting value is changed above or below 0.5 the weighting of the blend transition will change. A setting value of 0.5 will cause a linear blend, when half way up the hair strands the colour will be half of the tip and base colours.

Blend Bias = 0.25
Blend Bias = 0.5
Blend Bias = 0.75

Colour Salting

Using the colour salting feature adds random bleaching to individual hair strands. It allows the quick simulation of the nature phenomenon where random hair strand pigments have faded to towards white (lightened).

The probability of a hair being salted is set with the amount settings value and the strength of the salting is chosen at random between the Min and Max settings value.


Colour Salting Settings.


Min

This the minimum fractional value that the hair strands with salting can be faded to white by. This value needs to be less than the maximum value to function correctly.

Max

This the maximum fractional value that the hair strands with salting can be faded to white by. This value needs to be more than the minimum value to function correctly.

Amount

The fractional probability that the hair strand will be salted. A value setting of 0.0 will no hair strands to be salted and a value of 1.0 will result in all hair strands being salted.


Colour Peppering

Using the colour peppering feature adds random darkening to individual hair strands. It allows the quick simulation of the nature phenomenon where random hair strand pigments have are darker.

The probability of a hair being peppered is set with the amount settings value and the strength of the salting is chosen at random between the Min and Max settings value.


Colour Peppering Settings.


Min

This the minimum fractional value that the hair strands with peppering can be faded to black by. This value needs to be less than the maximum value to function correctly.

Max

This the maximum fractional value that the hair strands with peppering can be faded to black by. This value needs to be more than the minimum value to function correctly.

Amount

The fractional probability that the hair strand will be peppered. A value setting of 0.0 will no hair strands to be peppered and a value of 1.0 will result in all hair strands being peppered.


Preview

Generic hair preview settings are provided in conjunction with specialised preview settings related to the distribution.

Preview Settings.


Show All Meshes

Show all surface meshes contained in a character if used to spawn hair or not.

Show Follicles

Shows a preview of the generated hair follicles.

Show Hair

Shows a preview of the generated hair strands.

Show Hair With Widths

Shows a preview of the generated hair strands with accurate widths after the clump deformers are applied. This requires more system and graphics memory and may be slow with older graphics cards.

Amount

This percentage setting changes the amount of hair strands previewed. The hair strand width used for preview will also be inversely updated based on this percentage setting. Showing more hair strands will require more time to process and more memory to store the results, displaying more hair strands of complex hair styles is not recommend for older systems.

Use Preview Hair Colour

Switches between showing a preview hair strands with the optimal preview colouring and the unshaded colours used during rendering with 3Delight by the Garibaldi Express Material.
