Can you nest custom transformers? That is, can you put one custom transformer inside another?

• A. Yes, with no restrictions
• B. Yes, but you can only nest transformers of the same type (Linked or Embedded)
• C. Yes, but you cannot nest Linked Custom Transformers
• D. Yes, but only a single level of nesting

Answer: (A)

Nesting custom transformers is supported without restrictions. You can place a custom transformer inside another custom transformer, creating a hierarchy of reusable components. This works for both Embedded and Linked custom transformers, and there’s no limit on nesting depth. The nested transformer behaves like a normal transformer inside the parent, with its inputs, outputs, and parameters accessible as part of the parent’s graph. This enables modular design and reuse, letting you build complex workflows from simpler building blocks.

Some might think nesting is limited to the same type or only one level, but in practice both Embedded and Linked custom transformers can be nested, and you can nest them multiple levels deep.
