Fur
The Poiyomi Fur Shader is a system that uses a height-based technique to enable simulation of fabrics and hairs. It can look similar to how fur is simulated in animated films but with some differences.
To use Poiyomi Fur, select the shader version .poiyomi/Poiyomi Pro Fur. This exposes the Fur category with the following settings shown below.
Poiyomi Fur is an expensive feature, each layer increases the number of times your mesh must be rendered. Use it conservatively!
Layer Count
- Type
- Range
- Range
- 1to31
How many fur layers to use. The higher the value, the more fur simulation will occur.
Length
- Type
- Range
- Range
- 0to0.05
How much length the fur should be from the surface of the Mesh.
Gravity Strength
- Type
- Range
- Range
- -1to1
How much Gravity should be simulated on the fur.
Color
- Type
- Color
The Base Color of the Fur, if no Texture is defined.
Fur Texture
- Type
- Texture Slot
- Accepts
- Color texturesRGB On
Texture pattern to use as the fur.
Apply Fur Texture to Skin
- Type
- Toggle
If enabled, applies the Fur Texture to the skin's surface.
Mask
- Type
- Texture Slot
- Accepts
- Data texturesRGB Off
Texture slot to use for masking areas where Fur should only simulate.
Height Map
- Type
- Texture Slot
- Accepts
- Data texturesRGB Off
Specify which Height Map to use for the Fur. This is the main driver for the Fur simulation.
Height Map Min Max
- Type
- Clamped Slider
- Range
- 0to1
Determines the intensity of the Height range as determined by the Height Map.
AO
- Type
- Range
- Range
- 0to1
Intensity of Ambient Occlusion to use on the Fur simulation.
AO Min Max
- Type
- Clamped Slider
- Range
- 0to1
Determines the intensity of the AO range.
Hue Shift
- Type
- Toggle
Enables options to change the Hue of the fur color using the Animator.
Color Space
- Type
- Dropdown
- Options
- OKLabHSV
Choice of Color Space to use for the Hue Shift. By default, it will be set to OKLab.
Learn about the difference of Color Spaces as documented here in Color Adjust.
Select or Shift
- Type
- Dropdown
- Options
- Hue SelectHue Shiftdefault
This dropdown allows you to select how the Color Adjustment should behave when the Hue Shift is used. By default, this will be set to Hue Shift.
Select or Shift Options
Hue Select: Directly applies the selected Hue as an override to the entire Fur.Hue Shift: Only tints the Fur based on the lerped value. This is the default behavior.
Shift Speed
- Type
- Float
How much to constantly shift the hue with time. A value of 1 will result in a full hue shift cycle every 20 seconds.
Hue Shift
- Type
- Range
- Range
- 0to1
How much to shift the fur color around the hue circle.
This value is circular, and will have the same result at 0 and 1.
Advanced
Vertex Color Normals
- Type
- Toggle
If enabled, uses Vertex Color Normals for the Fur surface.
Min Distance
- Type
- Float
The minimum distance of the Fur.
Max Distance
- Type
- Float
The maximum distance of the Fur.
