After importing a dwg file (polymesh) from Maya to ACAD to Revit, it always renders with the default revit material. I tried to change the 'default' and 'default form' render materials in Revit > Manage > Materials, and also added materials to Manage > Settings > Objects > Imported - but nothing works. Although this changes the display material, it always renders in the white default. Is there a way to access the default render material to change it? Thanks.
