What is image masking
When an image is masked with a layer, a mask object is created in the design hierarchy.This object includes the mask and the related layers used for masking.
Best practices for masking
- All inner layers used for masking should remain under the mask object.
- Group these inner layers properly so only the intended images are included.
- Perform masking with a single group containing its masked object.

You did it!
Your masked images are now structured so Rocket can import them cleanly and keep your layout intact.
