COLLADA 1.4 Import
Defines how "round" the Splines contained in the COLLADA file will be displayed. To be exact, this value defines the number of subdivisions to be created. Larger values will result in a smoother, rounder shape, lower values can go as far as creating a square out of a circle.
Disable this option if you only want to import geometry and do not want to import Splines (or lines imported as Splines).
Depending on the program from which the COLLADA files are exported, geometry may contain lines that will be imported into Cinema 4D as Splines. These will then be superfluous in Cinema 4D.
An animation’s Position, Scale and Rotation will be imported.
When importing files from SketchUp it can occur that all materials are interpreted as transparent. Enabling this option prevents this and imports the materials correctly.
