Sometimes it is useful to increase the Threshold value to prevent minor details being reected.
Although minor details are calculated correctly, too much detail in reections can distract the viewer.
However, if you want all rays to be calculated, set Threshold to 0%.
Level of Detail
If you render into a viewport, the viewport’s level of detail value (Display
menu) is used in preference. The Level of Detail value here in the render
settings is only used for rendering to the Picture Viewer.
This value inuences all objects in the active scene that support a reduction in detail, such as metaballs,
primitives and NURBS. However, objects that have their own Level of Detail setting dened in a Display
tag will continue to use their setting. If the value is set to 100%, the objects will be rendered in full
detail. If the value is set to 50%, the objects will be rendered with only half their usual detail.
Multi-Pass
Multi-pass is ideal for trying out various lighting setups for your rendering
The setups will be rendered more quickly as a single multi-pass le than as
separate projects.
Multi-pass rendering makes it easy for you to post-edit your renders in compositing software such
as Adobe After Effects, Photoshop and Combustion. With multi-pass you can split the CINEMA 4D
rendering into separate layers such as shadows, reections, highlights and each separate light source.
You can save the layers in RLA, RPF, Photoshop (PSD) and BodyPaint 3D (B3D) format.
Suppose you’ve rendered a complex movie and the reections look too strong. With multi-pass, there’s
no need to re-render the CINEMA 4D scene. Instead, simply reduce the opacity of the reections layer
in your compositing package. Or why not include alternative lighting setups in the same rendering?
You’ll then be able to select the best setup during post-editing.
