Animation:
This section includes one option for the Resampling rate. When exporting an Alembic
animation, it is saved to disk using frames per second (fps). When importing Alembic data into
Fusion, the fps are detected and entered into the Resample Rate field unless you have changed
it previously in the current comp. Ideally, you should maintain the exported frame rate as the
resample rate, so your samples match up with the original. The Detected Sampling Rates
information at the top of the dialog can give an idea of what to pick if you are unsure. However,
using this field, you can change the frame rate to create effects like slow motion.
Not all objects and properties in a 3D scene have an agreed upon universal convention in the
Alembic file format. That being the case, Lights, Materials, Curves, Multiple UVs, and Velocities
are not currently supported when you import Alembic files.
Since the FBX file format does support materials and lights, we recommend the use of FBX for
lights, cameras, and materials. Use Alembic for meshes only.
Inputs
The AlembicMesh3D node has two inputs in the Node Editor. Both are optional since the node
is designed to use the imported mesh.
SceneInput: The orange input can be used to connect an additional 3D scene or
model. The imported Alembic objects combine with the other 3D geometry.
MaterialInput: The optional green input is used to apply a material to the geometry
by connecting a 2D bitmap image. It applies the connected image to the surface of
the geometry in the scene.
Basic Node Setup
The AlembicMesh3D node is designed to be part of a larger 3D scene. Typically, when
imported, a 3D geometry model is represented by one node, and any transforms are in another
node. The nodes imported as part of the Alembic file connect into a Merge 3D node along with
a camera, lights, and other elements that may be required for the scene.
