Fiber settings refer to settings per actual output curve. The term `fiber` is synonymous with the term `output curve`.

Automatically Resample Fiber:
Automatically Resample Fiber:
#id: LYNX_fabric_thread_fiber_general_resample
This auto resamples the input curves to account for the [Twist Cycles|#LYNX_fabric_thread_thread_twist_twist]. The `Segments Per 360` parameter controls how many segments are created for every 360 twists.
:warning:
When enabling this the resampling only takes the thread twist settings into account and not the fiber twist settings when calculating the resample density.
Detangle Fiber:
#id: LYNX_fabric_thread_fiber_general_detangle
Detangle the curves after they have been extruded around the input curves. Higher iterations yield better results. The detangling is only done on the [Rest Frame|#LYNX_fabric_rest_frame].

Randomize the twist cycles and twist offset per fiber. This is useful to break up the look and to introduce irregularities. Using small values is recommended.

Seed:
Sets the seed per fiber used for generating a random value between 0 and 1.
Min/Max:
Remaps the random value to this range and adds it to the twist offset.
Remaps the random value to this range and multiplies it with the twist cycle count / adds it to the twist offset.

If a scale attribute is present on the input curves, this will influence if the scale attribute is applied before or after the twist. This can be useful for "flat" threads.
