Used to group the hair strands together.

Property	Function
Width	width of the clump (similar to the scatter modifier)
Depth	depth of the clump (similar to the scatter modifier)
Width Density	the number of clump strands in each unit of the width. (for example, if “width=2” and “width density=10” then, we will have 20 clump strands in width.
Depth Density	the number of clump strands in each unit of the width. (for example, if “depth=2” and “depth density=10” then, we will have 20 clump strands in depth.
Width randomness	the randomness of the position of the hairs in width.
Depth randomness	the randomness of the position of the hairs in depth.
Translate X	Move the clump strands in the X direction
Translate Y	Move the clump strands in the Y direction
seed	randomness seed of the generating the clump strands.
strength	level of clump impact
strength randomness	set random value for strength
strength curve	Adjust the strength by curve (linearly and nonlinearly from the root to tip)
fly away	Hair strands escaped from the clump
seed	randomness seed of the applying clump modifier to hair strands.

• The dice icon in front of some properties creates random value. (by clicking on it)
• When the clump modifier is selected and you add another modifier, it will be placed under the clump and will directly affect the clump strands.
• You can drag and drop other modifiers inside/outside of the clump. modifiers inside the clump will just affect the clump strands.
