I try to do some furnitures to use in a layout file. If I respect the naming convention of the material ball (like described in the complete_technic_doc) the furniture appears on the game (the furniture is described in a layout file). But without color or without the adequate structur. If I doesn't respect the naming convention of the material ball (fg using the default name), the funiture would not appear ! I'm using 3DS MAX 2014 ! Any idea ? Thanks.
