Writes Bifrost points, strands, and meshes to an Alembic file. Make sure that at least one of this nodes' outputs is connected to the output node at the top level of the graph.

Inputs

meshes

The Bifrost meshes to write.

points

The Bifrost points to write.

strands

The Bifrost strands to write.

enable

If true, enables writing of files. Otherwise, this node simply passes its inputs through to its outputs.

filename

The file name.

directory

The directory.

frame

The frame number.

frame_rate

The desired frame rate.

start_frame

The start frame when the Alembic archive is created.

end_frame

The end frame when the Alembic archive is finalized and written.

overwrite

If true, overwrites existing file.

create_directories

If true, creates output directory hierarchy if it doesn't exist.

properties

A space-delimited list of properties to write.

write_single_file

If enabled, writes animation as a single Alembic archive. Note that frame_rate, start_frame and end_frame are only taken into account if this mode is enabled.

Outputs

out_meshes

Passthrough of the input Bifrost meshes.

out_points

Passthrough of the input Bifrost points.

out_strands

Passthrough of the input Bifrost strands.

success

True, if file was written successfully.

file_path

The full path of the written file.

Limitations

• An invalid Alembic archive (i.e. one which cannot be read again) will be produced if graph evaluation is stopped on a frame between start_frame and end_frame.
• Does not support writing data geo properties that have no specified target (this information can be viewed with a watchpoint).
• Does not support writing and subsequently reading recursively indexed properties.
• Writing the default values of properties is not supported.
• The Bifrost types uchar4 and float4 are written to Alembic as attributes of type color.
• Not all Bifrost types are supported natively by Alembic and properties with these types are currently not written to the Alembic archive. These types are: float3x2, float4x2, float4x3, float2x4, float3x4, double4, double3x2, double4x2, double4x3, double2x4, double3x4, char2, char3, char4, char2x2, char3x2, char4x2, char2x3, char3x3, char4x3, char2x4, char3x4, char4x4, short4, short3x2, short4x2, short3x3, short4x3, short2x4, short3x4, short4x4, int4, int3x2, int4x2, int3x3, int4x3, int2x4, int3x4, int4x4 long2, long3, long4, long2x2, long3x2, long4x2, long2x3, long3x3, long4x3, long2x4, long3x4, long4x4, uchar2, uchar2x2, uchar3x2, uchar4x2, uchar2x3, uchar3x3, uchar4x3, uchar2x4, uchar3x4, uchar4x4, ushort2, ushort3, ushort4, ushort2x2, ushort3x2, ushort4x2, ushort2x3, ushort3x3, ushort4x3, ushort2x4, ushort3x4, ushort4x4, uint2, uint3, uint4, uint2x2, uint3x2, uint4x2, uint2x3, uint3x3, uint4x3, uint2x4, uint3x4, uint4x4, ulong2, ulong3, ulong4, ulong2x2, ulong3x2, ulong4x2, ulong2x3, ulong3x3, ulong4x3, ulong2x4, ulong3x4, ulong4x4, bool2, bool3, bool4, bool2x2, bool3x2, bool4x2 bool2x3, bool3x3, bool4x3, bool2x4, bool3x4, bool4x4.
