The Shaderfx Game Hair shader allows you to view realistic game hair shading for models directly in the viewport. You can create this shader via the Create tab in the Hypershade.
Create polygon strips to model the hair. You can quickly generate these polygon strips using the Convert XGen Primitives to Polygons workflow. Apply the Shaderfx Game Hair shader to these polygon strips, then connect an opacity map to the shader to define the hair strands per strip, and a breakup map to provide controlled noise to make hair appear more realistic. You can then preview your hair shading in the viewport. You may wish to tweak your UV's per strip to add variety to your strand layout.
A selection of professionally painted opacity maps and a breakup map are provided for you in the /presets/Assets/Textures directory of your installation folder.
Upon creation of the shader, an opacity map and a breakup map are already connected by default.
After you have applied the shader to your meshes, you can adjust its attributes as follows:
Connect a map to add controlled noise to the hair, so that hair strands appear to intersect with and weave over and under each other, providing a more realistic appearance.
A texture is already connected by default. To map to a different texture, navigate to the file node connected to the Breakup Map attribute and select a different file via the Image Name attribute.
The texture map that defines the hair strands. It determines the opacity of the polygon strips so that each strip looks like a bunch of hair.
