I created a .dxf model of a red balloon using openfx software, and loaded it into flight gear according to David Megginson's "Mini-HOWTO: 3D Aircraft Models in FlightGear". I followed the instructions listed below:
The easiest way to load a new model is to set the property at startup with the --prop: command-line option; for example, to use a 3D aircraft model that you have installed in $FG_ROOT/Models/my-cessna.wrl, you could invoke FlightGear like this (under Unix-like systems):
fgfs --prop:/sim/model/path=Models/red_balloon.dxf
The balloon appears as it should, however I only get a black image of the balloon. I change the material settings in openfx to red, and the model renders in red, and appears in openfx designer as red. I export the model as a dxf file, but it appears in Flight Gear as black. Can anyone tell me what I am doing wrong. Thanks.
I don't know the DXF file format well, but I don't think it can export material settings like ambient, diffuse end specular color. Is there any other format to which you can export the model (like .obj or.3ds)?
