Tip:
In Cinema 4D R21, menu structures were changed slightly, mainly in the main menu.

The Mesh menu, for example, was restructured. Parts of it have been moved to the new Splines menu, the Mode sub-menu previously located in the Tools menu has been moved to the main menu, etc.

This may seem a little confusing at first for long-time Cinema 4D users (if you’re not only using the Commander anyway). If you prefer not to get accustomed to the new structure you can switch to the Cinema 4D Menu (Legacy) in the Layout menu, which will bring you back to the old menu strucure (this legacy menu will, however, be removed in the future).

Also, the tags in the Object Manager have been arranged under new sub-menus. This cannot be modified but the Commander mentioned above also works for tags if you want to quickly assign tags.

Tip:
Cinema 4D R21 cannot load scenes that were saved in Cinema 4D R4-R12. Open such scenes with Release Ï19, for example, and save them so they can be opened in R21. Visit labs.maxon.net for more solutions regarding such issues,

Tip:
The structure of the libraries in the Content Browser has been changed in Cinema 4D R21. It will be difficult for scenes that use Content Browser assets via a link to find these assets. As a workaround, open these scenes in Cinema 4D R20 and save them using the Save Project with Assets command. These scenes will then work independent of the Content Browser.

Tip:
Older plug-ins that were not created to work with Cinema 4D R21 will not work in R20. Please contact the respective plug-in developer for more information.

Tip:
Note that Cinema 4D is no longer installed in the Maxon directory but in the directory Maxon Cinema 4D R21.

Tip:
If you use OSX Mojave, the Color Chooser’s Color Picker can be disabled (grayed out). In order to make it possible for Cinema 4D to access the Color Picker, open the Mac system settings here: Security/Privacy. Add the executable Cinema 4D start file here.

Tip:
Make sure not to modify the installed program folders or their contents in any way (the only exception: The plugins folder - plugins can be placed here as usual)! If any modifications are made your software will not function properly! All user-specific information is saved to the user directory, including Content Browser libraries and similar elements.

Tip:
Cinema 4D always starts in OpenGL mode. If you experience Hardware OpenGL problems (i.e., a problem with the graphics card), quit Cinema 4D and restart Cinema 4D with the Ctrl/Cmd key held down until the messages Shift+Ctrl: Use Minimum Viewport Settings appears. Cinema 4D will then sart with reduced OpenGL settings (that you can increase again using the Main menu: Edit|Preferences|OpenGL setting) and Viewport settings (only Quick Shading in the Viewport, disabled Enhanced OpenGL, etc.).
