Please describe the feature you have in mind and explain what the current shortcomings are?
Add the ability to perform actions during construction with workfile template builder.
What is an action
An action is a plugin (like a loader) that is used to execute code.
Actions Type
Workfile Template Builder Actions
This Plugin/Code is executed at the build moment, two possibilities pre or post build.
Placeholder Actions
This plugin/Code is executed when processing a placeholder, the only possibility after processing.
Example
Workfile Template Builder Actions
The keep_placeholder option in the workfile template builder would be a post build action. It will remove placeholders like today. These actions would be listed in the settings of workfile template builder to enable them.
Workfile Template Builder Actions
In a scene with two placeholders, the first loads the model of an asset and the second loads the look of the asset. In this case the look is not applied. An action added to the placeholder will add the look to the model.
