Object Properties

Start of Animation
Reset

Using this setting you can offset the corresponding object’s animation temporally in relation to the information saved in the Alembic file. Clicking on the Reset button will set the animation start back to its original location.

Scale

Use this setting to scale Alembic objects at object level without having to re-import them.

Interpolation

See Interpolation

RELEASE 18

SDS Weight Scale [0..+∞%]

This setting can be used to adjust the weighting (if present) of imported Subdivision Surfaces. Make sure that you use values greater than 100%. This is necessary because there are Alembic files whose weighting can be greater than 100% (see Structure Manager). These will then be imported accordingly.

Use Original Path

Enable this option if the dummy object is already located in the open Project. You will then not have to re-enter the path to the Alembic file.

Path to Alembic File

As already mentioned here, the Alembic tags link to a separate Alembic file. This path will be set automatically when an Alembic file is opened. At the right you will find a selection button with which the link can be changed. At the right of the file selection button a green check mark or a red ,x’ shows whether or not Cinema 4D was able to locate the file.

Object Identifier

This is a unique ID that displays a link to the corresponding object in the Alembic file (don’t be confused by any unknown naming conventions - Alembic uses its own special naming conventions). At the right, a green check mark or red ,x’ shows whether or not Cinema 4D was able to locate the object.

Override Object for Rendering

When working in Cinema 4D it can be cumbersome working with high-res objects. It is easier to work with simple dummy objects that can be automatically replaced with high-res objects for rendering. Enable this option if a given object should be switched with another object (defined by the next two options) for rendering. Note that the same object type must be used.

Path to Alembic File

Here you can define the path to the Alembic file that contains the object to be rendered. If the Alembic file lies in the same directory as the Cinema 4D Project file, all you have to do is enter the object name.

Object Identifier

This is where you define the precise object ID of the dummy object for the rendered object in the Path to Alembic File field. To do so, open the corresponding Alembic file and copy the hierarchical path from the corresponding Alembic object. This object must be a polygonal object.

Only this object will be used - all Child objects will be ignored.

Update PSR

This option defines if the position, scale and rotation information from the animation in the Alembic file should be transferred to the corresponding object. This option will only be made available if the object has a PSR animation. If this option is disabled, the current animation state will be frozen. It can, for example, be animated briefly in Cinema 4D. However, if this option is then enabled, the Alembic file will define the object’s animation.

Update Geometry

This option defines if the geometry animation in the Alembic file (in Alembic files, an object’s vertices can be changed in number and position at any time, which in turn affects corresponding tags such as UVW, Normal, Selection, etc.) should be transferred to the corresponding object in Cinema 4D. If this option is disabled, the current animation state will be frozen. As soon as the option is enabled again, the Alembic file will define the animation.

Visibility

Use this option to determine if the visibility states saved in the Alembic file should be assigned to the object.

Tags

RELEASE 18

The following options show the respective functions as tags (which cannot be modified, copied or deleted). These will be marked with an a in the Object Manager to show that they are controlled by an Alembic file.

If these are disabled, the corresponding tag will no longer be displayed. If multiple UVW tags exist, these will work in conjunction with the normal Texture tag (arrange the Texture tag to the right).

Otherwise tags can be used as usual (e.g., a Polygon Selection tag can be linked in a Texture tag to restrict the material to a selection).

Normals

Use this option to define if the Normal tag should be evaluated/displayed.

UV Set

Use this option to determine if the UV tag should be evaluated/displayed.

Face Sets

Use this option to define if the Polygon Selection tag should be evaluated/displayed.

RELEASE 18

Color Maps

Use this option to define whether or not Vertex Color tags should be evaluated/displayed.

Creases and Corners

Use this option to define whether or not vertex and edge weighting for Subdivision Surfaces should be evaluated.

Other Attributes

Enable this option if the attributes saved in other tags (see also Other Attributes) should constantly be evaluated.
