Start Frame[-18000..3240000]

End Frame[-18000..3240000]

Use these settings to define the frame range of an animation to be exported. The animation prior to and after these frames will be omitted.

Frame Step[1..100]

This setting should be familiar to you from the Edit Render Settings menu (see Frame Step). Here it has the same effect on exported animations. Not every animation frame will be exported if a value greater than 1 is entered. For example, values of 2 or 10 will export every 2nd or 10th frame, respectively.

Subframes[1..100]

If you want to save subframes in addition to the ,normal’ animation frames, enter the desired value here. This value defines the number of animation frames in the Alembic file per Cinema 4D animation frame.

Example:

• You export an animation from frame 0-3. At a Subframe value of 2, the animation information at 0 0.5 1.0 1.5 2.0 2.5 3.0 will be exported.
• You export an animation from frame 1-3. At a Subframe value of 4, the animation information at 1.0 1.25 1.5 1.75 2.0 2.25 2.5 2.75 3.0 will be exported (note that exactly this last frame will be exported as the last animation state).

Subframes are, for example, required for calculating motion blur (Cinema 4D does not have the animation information saved in its own Timeline and depends on the information from the Alembic file).
