# Lena blue A-line skirt -- WORKING recipe (verified 2026-07-30, result:
# tools/tailor/lena_skirt_v1.zprj + lena_skirt_v1_garment.fbx/.obj).
# Run inside a bridge session (fresh scene; imports the avatar itself):
#   python tools/md_bridge.py --file tools/tailor/md_skirt_v1.py --timeout 500
#
# BOTTOMS LESSONS (tee lessons in md_tee_v1.py still apply):
# - Elastic waist during the drape KILLS it (cinches before the panels wrap
#   the body; garment slides off a hip). Hold bottoms up by TENSION instead:
#   garment waist (2x500=1000mm) < hip circ (1095mm) -- fabric stretch lets
#   it sit snug. Enable elastic only after full settle, if at all.
# - Strengthen through the WHOLE settle (250 frames), relax only ~50 at the
#   end -- soft fabric rolls into a bunch at the waist otherwise.
# - Drape each garment ALONE in a fresh scene: a second garment (even
#   frozen) grabs and inverts the new one. Game exports are per-garment
#   anyway; outfit photos are the only reason to co-drape, do those last.
# - New-fabric creation: fabric_api.AddFabric(r"<path>.zfab") -- a NAME
#   string silently fails and index 0 is the DEFAULT fabric shared by every
#   pattern (coloring it dyes everything). Assign via
#   pattern_api.SetPatternPieceFabricIndex(pattern, fabric) --
#   AssignFabricToPattern returns False for every arg order tried.
# - SHORTS (crotch bifurcation) are NOT solved: 2-panel notch construction
#   twists (fabric can't thread between the touching thighs; every seam
#   direction parity tried). Next approach: 4 panels arranged on the
#   per-LEG arrangement points (Leg_Front_L/R, Leg_Back_L/R) so fabric
#   starts wrapped around each thigh.
