Visibility Scale
These values determine the size of the irregularities in the X, Y and Z directions in relation to the
scene’s absolute Cartesian coordinates. If the noise effect is too severe, try reducing these values.
Illumination Scale
Use this setting to dene the size of the noise on lit objects. Lower values will result in rough noise,
larger values will result in ner noise.
Wind, Wind Velocity
Here you dene the wind properties for the noise, This will add realism to the animation since wind will
appear to blow the dust. The three Wind values dene the vectors of the wind direction in absolute
Cartesian coordinates (and/or local coordinates if the Local option is enabled). Use the Wind Velocity
value to change the wind’s strength.
Lens Effects
Lens effects cannot be displayed in QuickTime VR panoramas
CINEMA 4D can simulate the aberrations of real-world camera lens systems and lm material. Basic
sunbeams are brought to life with a solar corona or a halo. A lens reection of a low-quality camera
lens can be easily simulated, as rainbow colored circles develop and run diagonally across the screen.
A welcome aw in an otherwise too perfect virtual world!
Why not build a library of lens effects? You can produce many types of light
sources with different effects an save them as individual objects in the Object
manager. When you require one of these specic lights for your scene, simply
load it from your light source library.
You may recall that on the General page you have the option to disable light radiation (No Light
Radiation). If this option is enabled then the light source will no longer illuminate the objects in the
scene, but all lens effects of the light will still be visible. This is handy, for example, in a scene in which
the objects are already illuminated as you want and adding another light source for a lens are will
result in over-lighting the scene.
Try not to overuse lens effects; they can soon become distracting. Real world
the cameraman will try to avoid them.
The parameters for these lens effects are many and varied and take up two separate pages. You can
dene the basic effect on the Lens page. Use the Glow editor and Lens editor to rene almost any
detail of the lens effect.
