Can a smooth mesh be exported as an Alembic file?
As a basic rule of thumb, a completely smooth mesh will be exported without normals and thus produce the smallest Alembic file. This is reflected in the importer; an Alembic mesh without normals is loaded as a smooth mesh. If it has Custom Loop Normals then the loop normals are exported.
Can you export a file from Blender to Alembic?
For example, other software, such as Houdini or Maya, can export files to Alembic, which can then be loaded, shaded, and rendered in Blender. It is also possible to animate characters (or other models) in Blender, export to Alembic, and load those files into other software for further processing.
When to use cache modifier in Alembic file?
When importing an Alembic file, Mesh Sequence Cache modifiers are automatically added to time-varying meshes. For time-varying object transforms (so animation of rotation, location, or scale) the Transform Cache Constraint is used.
What should the sample count be for Alembic?
For example, if information for detailed mesh motion blur is desired, some subframes around the current frame can be written to Alembic by using a sample count of 5, Shutter Open at -0.25 and Shutter Close at 0.25. This mimics a “180 degree” shutter, opening 90 degrees before the frame and closing 90 degrees after the frame.
What do you need to know about Alembic Blender?
Alembic is an open computer graphics interchange framework. Alembic distills complex, animated scenes into a non-procedural, application-independent set of baked geometric results. This ‘distillation’ of scenes into baked geometry is exactly analogous to the distillation of lighting and rendering scenes into rendered image data.
What kind of data is stored in Alembic?
This ‘distillation’ of scenes into baked geometry is exactly analogous to the distillation of lighting and rendering scenes into rendered image data. Alembic is focused on efficiently storing the computed results of complex procedural geometric constructions.
