button ui_resetpos "Reset Position" width:160 height:30

on ui_resetpos pressed do
(
macros.run "Animation Tools" "TransformToZero"
)
)

rollout ResetPrmRollout2 "Reset Position2"
(
button ui_resetpos2 "Reset Position" width:160 height:30

on ui_resetpos2 pressed do

macros.run "Animation Tools" "TransformToZero"
)
)
)

custAttributes.add $.modifiers[1] Reset_position_attributes
