Need help using the Simple_Hair_UV script for creating hair uvs

[mickeal_alex]

Im using the Simple_Hair_UV script found in the Xgen UE documentation however when i imported my IGS alembic file that i exported, i has 3 different description and multiple splinegrp .
How do i add multiple groups and curves in the script?
Tried using " ; " and " , " in between each group and it doesn’t work.

Here is the part i am having trouple with, it's using Python.

curve_top_group= 'Herc_Flyaways|Herc_Hair_SplineGrp0 , Herc_HairBlend|Herc_Hair_SplineGrp0 , Herc_Hair|Herc_Hair_SplineGrp0'

It keeps giving me a sintax error, here is how the outliner looks like

Here is the default script:

from maya import OpenMaya import os def create_root_uv_attribute(curves_group, mesh_node, uv_set='map1'): ''' Create "groom_root_uv" attribute on group of curves. ''' # check curves group if not cmds.objExists(curves_group): raise RuntimeError('Group not found: "{}"'.format(curves_group)) # get curves in group curve_shapes = cmds.listRelatives(curves_group, shapes=True, noIntermediate=True) curve_shapes = cmds.ls(curve_shapes, type='nurbsCurve') if not curve_shapes: raise RuntimeError('Invalid curves group. No nurbs-curves found in group.') else: print "found curves" print curve_shapes # get curve roots points = list() for curve_shape in curve_shapes: point = cmds.pointPosition('{}.cv[0]'.format(curve_shape), world=True) points.append(point) # get uvs values = list() uvs = find_closest_uv_point(points, mesh_node, uv_set=uv_set) for u, v in uvs: values.append([u, v, 0]) #print (str(u) + " , " + str(v) ) # create attribute name = 'groom_root_uv' cmds.addAttr(curves_group, ln=name, dt='vectorArray') cmds.addAttr(curves_group, ln='{}_AbcGeomScope'.format(name), dt='string') cmds.addAttr(curves_group, ln='{}_AbcType'.format(name), dt='string') cmds.setAttr('{}.{}'.format(curves_group, name), len(values), *values, type='vectorArray') cmds.setAttr('{}.{}_AbcGeomScope'.format(curves_group, name), 'uni', type='string') cmds.setAttr('{}.{}_AbcType'.format(curves_group, name), 'vector2', type='string') return uvs def find_closest_uv_point(points, mesh_node, uv_set='map1'): ''' Find mesh UV-coordinates at given points.

Well as it turns out this script is limited and i found an alternate exporter that works better.
