All of the parameters on this page are mappable, meaning that you can connect texture maps to them to create specific effects. For an example of mapping, see Connecting a Texture Map to Hair Color Parameters.
Setting the Hair’s Transparency
The Hair Renderer shader lets you set the transparency level of the tips and roots of hair strands, as well as where their levels meet and blend.
• For a more realistic hair look (especially for white or light-colored hair), use lots of hair strands with a fairly high transparency value.
• Higher transparency also decreases shadowing because it allows light to pass through the hair volume. Having a very low transparency value for the roots can make the hairs opaque and look like hair plugs.
• To save time while previewing, deactivate the transparency in the Hair Renderer shader.
To set the hair strands’ transparency
1. Open the Hair Renderer property editor and click the Transparency tab.

2. Set the Tip and Root levels to have the hair completely opaque at the tip/root (a value of 0) or completely transparent (a value of 1).
3. Set the Root/Tip Crossover Center to define the point along the hair strands at which the transparency switches from the root to tip transparency value. A value of 0 is mostly tip and 1 is mostly root.
4. You can also control the blending between the root and tip transparency values by setting the Root/Tip Crossover Range. A value of 0 provides a sharp transition (no blending) and 1 is full blending.
