Dynamic lighting is computed in the Player as users and objects move about the scene.
Dynamic and static lighting are added together in the Player. For object that will move and rotate, it is best to light
them just with background light and the to use a dynamic light in the Player to represent the sun.
Effective Lighting Techniques
Here are some tips and techniques that may be useful as you explore Atmosphere's lighting.
•
An emissive surface used as a light that is twice as big will emit four times the light.
•
Spheres are good light sources that emit light equally in every direction.
•
If you use a Box object for a light, it may cause artifacts to appear in the scene. The larger the object the more
pronounced the artifacts.
•
Emissive surfaces can be hidden, so you can add a little light to a dark corner by placing a hidden, emissive object.
•
Texture images have their own lighting. Atmosphere lighting tends to darken them. To compensate for this, you
can increase the brightness of texture images before importing them into Atmosphere using Image > Adjustments
> Levels in Photoshop.
•
Viewpoint objects are not included in the pre-computed lighting calculations and they don't cast or receive
dynamic lighting shadows.
•
Viewpoint objects that are converted to Surface Objects are included in the pre-computed lighting solution, but
they loose any included animation.
