Export
A scene can also be exported to a foreign file format for subsequent work in other 3D software (the available options are described underImport/Export). Cinema 4D automatically adds the relevant file extension to the file. Each 3D program works differently, therefore it is not always possible to convert all information within a scene. Further, the result will always differ according to the materials and lighting used, so a manual re-working may be necessary.
All exports will be treated as commands, i.e., they will, for example, be listed in the Command Manager and can, for example, be assigned keyboard shortcuts or be added to palettes or menus. If the export function has options, these can - as is the case with other commands - be accessed by clicking on the cogwheel icon.
If the Shift key is pressed when the command is called up, only the currently selected object will be exported.
This export format is useful for game developers because Cinema 4D can be used as an editor with which physics can be exported. The exported *.bullet file can then be incorporated into a bullet-based game engine.
It can export all except the following:
- Soft Bodies
- All forces (Spring, Motor, Force, Particle Fields, as well as Spring on a wheel connector).
- Combined Connectors (i.e. when two Connectors are connected directly with each other).
- If Trigger is set to On Collision or At Velocity Peak (Dynamics Body tag)
- A Cone object will always be exported as a Bullet Cone, which does not allow an elliptical cross section or a clipped off tip (Upper Radius must always be set to 0 and a different center point). Cylinder, Oil Tank and Capsule will always be exported as Bullet Cylinder or Bullet Capsule (depending on which is more appropriate; again, no elliptical cross section is possible and the convex surfaces of the oil tank area also not allowed). A Sphere will also be exported as a Bullet Sphere and may not be elliptical in shape.
In other words, the following can be exported:
- Rigid Bodies
- Connectors not connected with each other
- Geometry - with a couple of limitations for Cone, Cylinder, Oil Tank and Capsule.
