Clumping

Causes the fibres in Input 0 to clump around the fibres in Input 1, the amount of clumping is based on the

Inputs

Clumping

Parameter Description
Weight an overall weight of the effect.
Weight Random a means of randomizing the effect.
Tip/Base Attraction how much the fibres attract to the tip/base of the clump, 1 is completely, 0 is none and -1 will actually push the fibre away.
Attraction Bias controls where along the clump the transition from base to tip happens.
Min/Max Distance defines a limit to how close and far the fibre will be attraction to the clump.
Twist causes the fibres to twist themselves around the clump.
Fly Away the higher the value the more fibres will fly away from the clump, adding a frizz effect.

Geometry

Parameter Description
Space defines whether the clumping should be evaluated in Local or World space, this usually depends if you’re clumping around Fibres or a guide curve.
Maintain Length by default Yeti tries to maintain the length of the fibres, in some circumstances this can lead to uneven looking results due to longer segment lengths - toggling this off helps produce smoother results with the side effect that the overall length of the fibre may be slightly different.
Length Handling depending on the configuration of your graph there are situations ( especially when using guide curves ) when a fibre is longer than a clump, this can cause stray looking hairs. Turn this to Conform If Longer will cause fibres that are longer than a clump to conform to the length of the clump.
Obey Weight this will control how the output fibres will behave if Conform if Longer is true and the fibre is longer, if on the Weight parameter will be take into consideration, anything with a weight of 0 will be completely ignored thus retaining their lenght.
