Add Grain (Slow)
At top, a low “Samples” value; at bottom, a higher “Samples” value.
This is another way in which to avoid the artifacting mentioned in “Samples” above. A grainy rendering
will be used to eliminate any visible light source structures. The “Samples” value should be high
enough to avoid an extremely grainy look. On the other hand, such a grainy look could be just what
you want...
The render times will be quite a bit longer compared to “normal” (with “Add Grain (Slow)” deactivated)
rendering.
Show in Render
Caption: Active “Show in Render” and “Show in Reection” options.
Activate this option if you want to render the Area light source itself. Depending on brightness, the
light source will, in most cases, be rendered white.
Area lights with no actual area (surface), such as “Line” or splines, cannot be rendered.
