Subdivs – Controls the number of samples to use when defining the quality of the final rendering of the material. Lower values will render faster, but the result will be noisier. Higher values take longer but produce smoother results. This parameter is only available when Use local subdivs is enabled in the Global DMC settings. This parameter is not available when the renderer is set to GPU. Random Melanin – Adds variation to the amount of melanin in each hair strand. Random Dye Hue – Adds variation to the hue component of the dye color. This makes each strand appear with a different dye color. This parameter has no effect, when the dye color is not used, i.e. when the dye color is pure white. Random Dye Saturation – Randomizes the saturation of the dye color between hair strands. This makes each strand appear with a more or less saturated dye color. This parameter has no effect, when the dye color is not used, i.e. when the dye color is pure white. Random Dye Value – Adds variation to the value component of the dye color. This makes each strand appear with a brighter or darker dye color. This parameter has no effect, when the dye color is not used, i.e. when the dye color is pure white. Random IOR – Randomizes the ior value for each hair strand. This makes some strands more reflective, and others - less reflective. Random Tangent – Adds a random offset to the hair tangent. This makes the hair stands receive light from slightly different directions, which also means that the highlights will be placed in slightly different places for each strand. Note that this parameter is depends on the scene scale. Random Glossiness – Randomizes the glossiness of each hair strand. Random Softness – Assigns a random value for the softness parameter for each strand. This makes some hair strands appear crisper, while other appear softer. Random Highlight Shift – Adds variation to the highlight shift for each strand. This offsets the highlights closer or further away from the root of the hair on a per strand basis. Glint Strength – Controls the strength of the colored highlights across and along the strand. Glint Variation – Adds a random glint variation along the strand. It affects the glint strength and orientation; the original secondary highlight strength and orientation; the softness, glossiness and highlight shift. Glitter Strength – Controls the glitter strength. Glitter is the additional more focused colorless highlight, which is randomly scattered along the strand. It is more pronounced with hard lighting produced by small or collimated light sources. For more information, see the Glitter Strength example below. Glitter Size – This parameter controls the size of the randomization pattern applied. Increasing the value increases the size of the pattern. For more information, see the Glitter Size example below. Glitter Scale – Internally, the variation along the strand is set in real world units. This parameter allows correction of the appearance of hair not modeled in real world scale. Values below 1.0 shrink the variation pattern, while values above 1.0 elongate it. For more information, see the Scale example below. |
