Starting with 1.7 and The Vault of the Galaxy, we recommend using a single fixed scale for all 3D models. Instead of changing the size of an object to fit the viewport, we zoom the camera until the viewport fits the object.
We recommend the following metrics:
3D models scale: 0.1 units per meter.
Object position: At origin.
Camera position: X=0 Y=-400 Z=800.
Camera directon: Pointing to origin (angles: 153.44 0.0 180.0)
Camera viewport: Centered on origin, zoomed to fit object.
Note: You will need to specify a viewportRatio in the image descriptor in order for the engine to have the proper 3D projection parameters. The viewport ratio is the ratio of the viewport width to the height of the camera.
Light Settings
The main light source is an infinite, soft-shadowed, white light source:
Light position: X=-500 Y=300 Z=500
Light direction: Pointing to origin (angles: -149.04, -40.61, 47.33)
Note that from the camera's perspective the object is slightly backlit. This accentuates shadows and evokes the darkness of space.
