I would like to know if there is a way to export a fbx city mesh with shapegroups and have a custom name instead of Cityengine_Material_1,Cityengine_Material_2, Cityengine_Material_3 etc... ?
hi & sorry about the late reply.
i just verified with CityEngine 2016.1: if i specify a material called 'red' via CGA set(material.name, 'red') it appears in maya as material "red_mat". CE appends "_mat" to differentiate the object from any geometry called 'red' (required by fbx).
which CE version are you using?
