Files

General

Recent Files[0..100]

This value defines how many of the most recently opened files appear in the File menu(see Recently opened files).

Backup Copies[0..1000]

With this setting, you can make several backup copies (see previous setting Backup Copies). These are then numbered consecutively: *.bak, *.bak1, *.bak2, etc.

Link Assets

You will be familiar with the message from Cinema 4D if, for example, you want to load a bitmap that is not local - i.e., not in the project path or "tex" - into a material: "The asset is not in the search path of the project. Do you want to create a copy in the project directory?". This allows you to define whether the asset should be saved with a relative or absolute path.

If this question keeps bugging you, you can define what should happen by default here. You have the following options:

2025

Render Output Behavior

As already described at Save, you can define how existing, saved images are to be handled during rendering. You can select from the following options:

Auto-Save

You can use these options to have Cinema 4D automatically save copies of the open scenes at certain intervals.

2025
Note: Since Cinema 4D 2025.1, automatic saving is asynchronous - a copy of the scene is created in the memory and written to the data carrier. This trick means that work in Cinema 4D is no longer interrupted during autosaving: very practical for very large scenes that sometimes take minutes to save.

The file copies are saved according to this naming scheme:

Save

Every (min)[1..10000]

Enter the time interval at which scene files should be saved here. If nothing is changed in the file, it will not be saved.

Limit

To (Copies)[1..1000]

If you define relatively short intervals, you will receive a huge number of files within a short period of time with correspondingly large storage space requirements. Use this parameter to limit the number of copies. The oldest file exceeding this number will be deleted.

Save to Folder

Here you have 3 options with which you can define where the copies should be saved:

The next two options refer to the behavior of XRefs when loading and saving.

Deferred Refresh on Open

Activate this option if you do not want all XRef objects to be updated every time a master project is opened. This can greatly speed up the opening of a scene. This is particularly the case when Cinema 4D has to search through many paths. Please note that if this option is activated, you must update the XRef objects manually by clicking the button.

Reduced References on Save

If this option is activated, all XRef objects will automatically be unloaded when they are saved. This allows you to save a lot of memory (by default, all objects contained in XRefs are completely contained in the master project and are no longer mere instances, as in previous versions).

Paths

The Add Directory button below can be used to add new asset paths, which will then be added to the list here. To use this interface element, please refer to Path lists.

Cinema 4D searches for material textures and other assets (such as sound files) at specific locations:

In some scenes, certain assets may not be found under these paths (e.g., if you make assets available via a network). Although you can correct the paths individually, this is very annoying for many assets in the long-term.

Cinema 4D therefore offers you the option of assigning any number of replacement paths. If the editor or the raytracer does not find an asset in the directories deffined above, the replacement paths will then automatically be searched (the bitmap shader also searches all associated subdirectories).

Note: Be careful not to define optical data carriers or network paths. Depending on their size, these paths will usually be searched very slowly. An error message will only appear if the asset is not available there either.

The following applies to Node materials: No recursive search through all subdirectories will take place. Instead, relative paths can be used here, e.g., in the following form: "./directory1/directory2/texture.tif" (the path will automatically be generated when a texture is selected in the search paths). This path is then used in all search paths (see above) searched.

Paths as Watch Folders

Activate this option if you want to simultaneously define the folders defined under Paths as monitored folders. Their files will then be displayed in the Asset Browser.

Default Scene

Whenever Cinema 4D is restarted or a new scene is created, e.g., via File/New Project, either an empty scene, a complete sample scene with the Cinema 4D logo or an individually specified scene can be loaded. This can be helpful if you want to find a standard light setup or a material library in every new scene, for example. You can therefore use this setting to define what should happen when a new scene is created. The following options are available:

In the latter case, there are 2 ways:

Click on the folder icon to the right of the file path field displayed directly below this selection menu and navigate to the desired Cinema 4D file on your storage medium. Or:

2025

Click on the Asset Browser icon to the right of the folder icon; an Asset Browser window will open in which you can select any scene file.


Note 1:

In earlier Cinema 4D versions it was possible to save any project file under the name new.c4d in the program directory of Cinema 4D and thus always have this scene loaded as the default scene. This option is no longer available from version 2024.1. Instead, use the Custom scene setting and then enter the desired file for loading.

Note 2:

There is also the option to save a currently open scene as a new standard scene. To do this, call up the command Save as Default Scene in the main menu Window/Customize. This saves the current scene under the name new.c4d in the Cinema 4D presets directory and automatically loads it from there when Cinema 4D is opened and each time a new project is created. This is possible because the Default Scene mode is automatically switched to Custom Scene and new.c4d will be linked accordingly.
You can open the preset directory at any time after opening the Preferences by clicking the Preset directory button at the bottom of the settings window.
