Custom Skin Tone

The Custom Skin Tone section allows you to modify the general tone and appearance of the arm. This control can be activated directly from the shader and provides several preconfigured options ranging from light to dark complexions.

To enable it:

1. Open the Shader Editor in Blender.

2. Locate the "Arms" material and enable the "Custom Tone" option.

3. In the "Skin Tones" node, choose a preset from the available list:

• Albino

• Fair

• Light Olive

• Golden Tan

• Warm Brown

• Deep Tan

• Medium Dark

• Deep Brown

• Ebony

Each tone adjusts the melanin and subsurface parameters to achieve a natural result.

Light Areas Mask:

This slider controls the visibility of lighter skin zones typical in darker complexions, such as the palms, knuckles, or finger edges. Increasing its value enhances the contrast between these regions and the rest of the skin.

Note: Skin tone parameters are physically based and optimized for realistic results. Adjust them gradually — small changes are usually enough to achieve a natural and consistent appearance.

Basic Adjustments

The Basic Adjustments section provides general visual controls for the skin material. These parameters affect the overall look and surface behavior of the arms and can be used to fine-tune the selected skin tone.

Hue:

Shifts the overall hue of the skin color. Useful to slightly warm up or cool down the tone.

Saturation:

Increases or reduces the intensity of the color. Lower values create a more desaturated or pale appearance.

Color Value:

Adjusts the brightness of the surface. Increasing it makes the skin lighter; decreasing it darkens the overall tone.

Roughness:

Controls how glossy or matte the skin appears. Lower values make the skin look shinier, while higher values produce a softer matte surface.

Specular:

Defines the amount of light reflected on the surface. Adjust this to balance the highlights depending on the lighting setup.

Subsurface Scale:

Determines the scattering depth of the subsurface layer. This helps keep the skin looking realistic under different lighting conditions.

Subdermis:

A color control that affects the lower layer of the skin. Adjusting it can subtly modify the warmth or tone of the underlying tissue.

Displacement:

Adds depth and surface relief to the skin microdetails. Moderate values are recommended to preserve realism.

Note: These controls work on top of the selected skin tone. Changes to roughness, specular, or subsurface can affect how the material reads under different lighting — test under more than one light setup before finalizing.

Tattoo Template

Inside the main textures folder of the model you will find the file "Arms_Template.psd". This template must remain in the same directory where the .blend file was originally unpacked. Blender uses relative paths to locate textures, so if the file is moved or renamed the material will not be able to find it automatically.

The template provides a complete 2D layout of both arms with clear orientation guides. It shows the front and back areas of each arm, including shoulders, elbows, wrists, hands, and fingers. The layout is organized to make it easy to position your own tattoo designs accurately.

When opening the file in a PSD-compatible editor (Adobe Photoshop, Affinity Photo, GIMP, or similar) you will see the following layers:

Design Layer:

Empty layer at the top where you can add your own tattoo artwork or graphic elements. You can create additional layers above this one for separate designs.

Arms_Template-Layers (do not paint here):

A folder containing internal reference layers used to build the guide. These should not be modified or painted over.

INFO (Hidden by default):

Contains extra information about how to use the template. You can enable it if you need a quick reference inside your editor.

Legend:

Shows the names and orientation of each section of the arm, such as "Outer forearm", "Elbow pit", "Palm", etc. This helps to place your design correctly on the 3D surface.

Areas:

Marks the regions that correspond to specific body parts like the knuckles, shoulder, or elbow. These are useful for precise placement of small details.

Edges:

Defines the visible limits of the texture. Designs should stay within these boundaries to avoid stretching or visible seams on the model.

Above the folder "Arms_Template-Layers" you can freely add new layers with your custom tattoo designs. Keeping this structure ensures that the visual guides remain intact and your artwork stays organized.

Painted Nails

The Painted Nails section provides all the controls for customizing the appearance of painted or decorated nails. These parameters are independent for each hand, allowing you to apply paint or designs selectively.

Painted / Natural — Right Hand:

Activates or deactivates the painted nail mode for the right hand. When disabled, the nails remain in their natural state.

Painted / Natural — Left Hand:

Activates or deactivates the painted nail mode for the left hand. You can enable both or customize each hand independently.

Template / Color:

Determines how the nail paint is applied. When disabled, the nails use a uniform color defined by the color picker below. When enabled, the system uses the "Nails_Template.psd" file, allowing each nail to display its own custom design or pattern.

Custom Color:

Defines the solid color used when the Template / Color option is disabled. This can be any tone, from neutral to vibrant, depending on the desired style.

Metallic:

Adds a metallic reflection to the paint layer. Increasing this value produces shiny, reflective finishes such as chrome or metallic nail polish effects.

Paint Normal:

Input for a normal or bump map. By default, it is connected to an internal noise texture that simulates the subtle irregularities of nail polish. You can replace it with any custom normal map to create unique surface effects.

Normal Strength:

Controls the intensity of the normal or bump detail applied to the nail surface. Lower values keep the surface smooth, while higher values emphasize the relief and reflections of the paint layer.

Nails Template

Inside the main textures folder you will find the file "Nails_Template.psd". This template provides the complete layout of both hands and allows you to design each nail independently.

The PSD file must remain in the original textures directory next to the .blend file to ensure that Blender can locate it correctly. Moving or renaming the file may cause the material to lose its connection.

The layout clearly separates the nails of both hands, labeled by finger (Thumb, Index, Middle, Ring, Pinky) for easy identification and precise placement of designs.

When opened in a PSD-compatible editor (Adobe Photoshop, Affinity Photo, GIMP, or similar), the template includes several guide layers similar to those used in the arms template — Design Layer, INFO, Legend, and Edges — which serve as visual references for orientation and boundaries.

You can freely add your own artwork or color layers above the existing structure to create personalized nail designs for each finger.

Applying Nail Designs

Important: Any area left transparent in the template (alpha channel) will appear black in Blender. Make sure every nail area is filled with a solid color or design before saving the PSD.

To create and apply custom nail designs, open the file "Nails_Template.psd" located in the textures folder of the model. Each nail corresponds to a labeled area in the layout, allowing you to paint or place designs individually.

1. Open the template in a PSD-compatible editor.

2. Add your colors, patterns, or logos on new layers above the existing structure.

3. When finished, hide the folder "Nails_Template-Layers (do not paint here)" so that only your artwork remains visible.

4. Save the file using File > Save (Ctrl+S).

5. Back in Blender, open the Shader Editor and go to the "Nails" material. Enable the "Painted / Natural" option for the right hand, left hand, or both. Make sure "Template / Color" is enabled so that Blender uses your PSD file. The designs will appear instantly on the corresponding nails.

If the texture does not update after saving:

• Switch from Rendered or Material Preview to Object mode and back again, or

• Toggle the "Template / Color" option off and on to force Blender to reload the file.
