## Objects

### Hair

Parameter ID: `HAIR_RENDER_OBJECTS_HAIR`

Use this setting to define if hair on Hair objects should be rendered.

### Polygon

Parameter ID: `HAIR_RENDER_OBJECTS_POLYGON`

If you assigned a (Hair) Render tag to a polygonal object without assigning it a Hair material, hair will be applied to the complete object. Use this setting to define if these polygonal objects should be ignored globally with regard to rendering.

### Spline

Parameter ID: `HAIR_RENDER_OBJECTS_SPLINE`

Use this setting to globally define whether or not splines to which a Hair material has been applied should be rendered.

### Particle

Parameter ID: `HAIR_RENDER_OBJECTS_PARTICLE`

A Hair material can be applied to emitters or geometry objects (Thinking Particles). Particles will then be rendered as hair. Use this setting to define globally whether or not Hair particle effects should be rendered.

### Length

Parameter ID: `HAIR_RENDER_HAIR_LENGTH` · Range: [0..+∞m]

### Count

Parameter ID: `HAIR_RENDER_HAIR_COUNT` · Range: [0..2147483647]

(Hair) **Length** and (Hair) **Count** apply to polygon or Generator objects to which only a Hair material was applied, without using a Hair object. Use this setting to globally define length and count. Length and count can also be defined for each object individually in the (Hair) Render tag.

### Mode

Parameter ID: `HAIR_RENDER_OBJECTS_MODE`

Use this setting to define if the objects (if any) placed in the **Objects** field should be included in or excluded from rendering.

### Objects

Parameter ID: `HAIR_RENDER_OBJECTS`

Place all objects that should be included in or excluded from rendering into this field (Hair objects, objects containing a (Hair) Render tag or Hair material or an object linked to a Hair object). Use the hierarchy icon to the right of the object to define, whether or not child objects should also be included or excluded.
