RenderMan 23.1 introduces the possibility to modify the contents of an existing Alembic archive as its contents is delivered to the renderer.
The shape editor uses the same logic as the RLF Editor: create rules to modify any nodes matched by an expression.
To create an edit, right-click in the edit field (teapot icon) and select the required options. The edit will appear in the field in plain English.
Relaunch the render to see your changes.
When a parameter is set to default, it means that it will be omitted and the renderer's default value will be used. Some defaults may change based on your rendermn.ini settings. See docs for more details. |
There are 3 matching engines:
Rules are evaluated in the editor's order. Because matching can be slow in large archives, the first matching rule will win and stop the process. |
You can either double-click in the field to type your expression or drag and drop from the alembic node list.
To drag and drop, you must first select the node in the alembic node list. |
The chosen subdivision basis and interpolate boundary settings will define the shape's look.
This table shows all the combinations.
