With some complex scenes, you may be unable to move objects smoothly in the viewports with full shading due to hardware limitations such as processor speed.
To help resolve this issue, Cinema 4D estimates how long it will take to refresh the viewports. If the estimated time exceeds the redraw time limit specified here, a faster display mode will be used automatically. For example, Quick Shading will be reduced to Wireframe. Or, if the wireframe mode is still too slow, Box will be used instead.
The default value is 400 milliseconds. To prevent a less detailed display mode from being used, set Redraw Limit to a very high value such as 10000 milliseconds.
This option defines whether an animation will play in all 4 Viewports (enabled) if you open the 4-panel view or if the animation will only play in the active Viewport (disabled).
If enabled, the corresponding parameters will be updated continuously in the Attribute Manager while the animation is playing.
This can help to prevent viewport slow-down when working with complex scenes.
This option defines whether or not changes made to materials in the Material Manager - e.g., if when the color slider is moved - should be displayed continuously (option enabled) in the Viewport or after the mouse button is released (option disabled). A more fluid parameter adjustment can be achieved in particular when using the RadeonPro preview if this option is disabled.
These values specify the ratio of a pixel’s on-screen width to its on-screen height. the monitor aspect for most monitors is 1:1.
However, some display media use a pixel ratio other than 1:1. This will lead to distortion unless the pixel ratio is adjusted accordingly.
For example, circles will appear to be ellipses. To calculate the pixel ratio manually, expand the editor window to fill the entire screen. Select the side view and create a cube. Measure the width and height of the cube with a ruler and enter the value into the value field.
In the following you will find information regarding Color Management.
Define the ICC hardware profile for your display hardware (most often a monitor) here. Everything that Cinema 4D displays on your monitor - Viewport, color selector, rendered images in the Picture Viewer, etc. - will be displayed using this color profile (the same settings can be found in the Image Color Profile settings when saving rendered images).
ICC profiles can be obtained from hardware manufacturers. These values can also be incorrect due to variations in the manufacturing process. If you want to make 100% sure you have the correct color profile you must calibrate the device yourself using the appropriate calibration device.
In most cases you will not have to modify these settings because your computer’s operating system will use its default monitor profile. However, this automatic calibration can be (or become) faulty. In such cases you can adjust the profile manually.
Clicking on the button at the right will make a selection menu available with the following options:
Cinema 4D will ignore the monitor’s color profile and use uncorrected RGB values for display.
This command does not save the monitor profile to the Preferences but loads them from the computer’s operating system each time the application is started.
Here you can manually load an ICC profile (if you have calibrated your monitor
you will be given an ICC color profile file that can be loaded here but which will normally be supplied by your operating system automatically). If an image or a video with an integrated profile is loaded here, this image or video will be used.
Saves the current ICC profile as a file.
The operating system’s current monitor profile will be read (when command is selected) and saved to the Preferences.
An sRGB profile (which should always be used if no other profile has been specified) or a Linear profile can be defined.
