When enabled, a vertex uv attribute will be generated for the output surfaces, based on the parameters below, if one isn’t already on the input. U corresponds with the input curve parametric coordinate, and V corresponds with the parametric coordinate around the axis. When Surface Type is Points, this will be a point uv attribute.

When enabled, a vertex uv attribute will be generated from scratch for the output surfaces, based on the parameters below, even if one is already on the input, instead of copying the UVs from the input.

When enabled, the individual U and V coordinate distances will be scaled, relative to other edges, by the corresponding edge lengths. When Normalize Computed Us and Normalize Computed Vs are on, U and V coordinates will still be scaled to be within the 0 to 1 range, but along the curves or cross sections, the relative lengths in UV space will be proportional to their lengths in physical space. See the image below.

When enabled, the U coordinate will be scaled to go from 0 to 1, (before UV Scale is applied). Otherwise, U will correspond with the average distance around the cross sections on the mesh, ignoring any stretch applied by Stretch Around Turns. Either way, U can be scaled by the first component of UV Scale. When this is enabled and Normalize Computed Vs is disabled, V will be scaled such that U and V appear scaled similarly in space, though depending on the Use Max Cross Section Length per Curve for Proportional Scale option. This is especially useful for things like applying repeating rope textures, where the texture should be applied isotropically. See the image below.

When enabled, the V coordinate will be scaled to go from 0 to 1, (before UV Scale is applied). Otherwise V will correspond with either the average distance along the mesh in the V direction or the distance along the backbone curve, depending on the Use Mesh Edge Lengths instead of Curve Edge Lengths. When this is enabled and Normalize Computed Us is disabled, U will be scaled such that U and V appear scaled similarly in space. See the image below.

When Normalize Computed Us is disabled and this is enabled, the range of U is rounded to the nearest positive integer, in order for textures to wrap correctly in the U direction. This rounding is applied after the corresponding component of UV Scale is applied, so that UV Scale can still be approximately a scale per length unit for small geometry when both Normalize Computed Us and Normalize Computed Vs are both disabled. See the image below.

When Normalize Computed Vs is disabled and this is enabled, the range of V is rounded to the nearest positive integer, in order for textures to wrap correctly in the V direction. This rounding is applied after the corresponding component of UV Scale is applied, so that UV Scale can still be approximately a scale per length unit for small geometry when both Normalize Computed Us and Normalize Computed Vs are both disabled. See the image below.

When this is enabled, any computed U values will be replaced with maxu-u, (e.g. 1-u if Normalize U is enabled and UV Scale has 1 for the first component), to avoid textures appearing backward. This should be on for textures to appear correct on surfaces viewed from the front, (i.e. normals pointing toward the camera), and should be off for textures to appear correct on surfaces viewed from the back, (i.e. normals pointing away from the camera). See the image below.

An additional scale on the generated UV coordinates. When Normalize U or Normalize V is on, the corresponding scale is applied after normalization. Otherwise, this scale is a scale per length unit, e.g. 0.5 would correspond with a period of 2 length units. If Make Computed Us Wrap Seamlessly or Make Computed Vs Wrap Seamlessly is enabled, the corresponding scale is applied before rounding to a positive integer number of repetitions of the U or V space, so that textures will still wrap correctly.
