Flux ArtWhy do other screens change after replacing one screenshot?
If replacing one mockup screen also changes other layouts to the same screenshot, first check whether they share Smart Object content instead of immediately redoing perspective mapping. Once downloaded Flux Art assets enter Photoshop, the external project determines copy relationships. Preserve the approved project and create a separate diagnostic copy. Confirm the screenshot intended for each screen, then choose shared or independent content. Different layer names do not prove that content is independent.
Map instances instead of guessing from names
List artboards, layers and intended screenshot versions in a table, marking instances allowed to change in this round and those that must remain unchanged. Check whether each object is ordinary pixels, an embedded Smart Object or a linked object referencing an external file. Record unknown types as unknown rather than classifying them by similar thumbnails. Embedded describes how content is stored; independent describes whether copies share content. These are different judgments. Even without an external file path, several embedded instances may update together when their content changes.
Ordinary and independent copies use different commands
Adobe Photoshop's instructions for duplicating embedded Smart Objects distinguish two operations: Layer Via Copy creates a copy retaining the content connection; New Smart Object Via Copy creates an independent content copy that does not receive changes to the original object's content. Checked on October 19, 2026: https://helpx.adobe.com/photoshop/desktop/create-manage-layers/smart-objects/duplicate-an-embedded-smart-object.html . This concerns propagation of content edits, not a claim that all instance positions, perspective transforms or effects automatically match. Check menus and applicable object types in the actual software version; do not apply embedded-object procedures to linked objects without confirmation.
| Observed situation | Relationship to distinguish | Verification action |
|---|---|---|
| Different layer names, but images change together | Several instances may share content | Edit content in a copy to observe the actual scope |
| Embedded object has no external path | Storage method is not content independence | Check duplication method and content coupling |
| Several layouts must share one logo update | Intentional shared content | Record every instance allowed to update together |
| Each screen needs a different screenshot | Independent content is needed | Create independent copies and check each one |
| One external-file edit updates several places | Multiple references to one linked source | Check the source and approve the impact scope first |
| Content is correct but screen cropping is wrong | Object relationships and geometry are separate checks | Review transforms, occlusion and text |
| Temporary test marker remains in the export | Diagnostic content was not removed | Stop delivery and recheck the final file |
Sharing is not necessarily wrong; establish design intent first
When the same approved logo appears across several layouts, the team may want one content edit to update all of them. Different feature screenshots across multiple phone screens usually need independent content. Decide according to delivery requirements instead of separating or linking everything indiscriminately. Shared content reduces maintenance steps but broadens the impact of accidental changes. Independent copies are easier to edit separately but may miss common-element updates. Record the chosen relationship and reason so the next colleague does not work from the opposite assumption.
Test the actual update scope with a reversible marker
Add an obvious temporary marker inside the target content in the diagnostic copy, save it, and inspect all potentially related artboards rather than only the current screen. Record which instances changed and which remained unchanged. Then undo the marker or close the diagnostic copy, ensuring it never enters the delivery version. This is a recommended scope test, not a hands-on test of a real client project. If the actual scope differs from the table, stop replacing approved screenshots and inspect object relationships. Renaming files or locking layers does not establish content isolation.
A hypothetical three-screen mockup
Suppose three phone mockups were ordinary copies of one embedded object, and the second needs a settings page while the others must retain the home page. This is a hypothetical example, not a real project result. In a working copy, create an independent content copy for the second screen, replace it with its approved screenshot, and verify that the other two retain the home page. A new layer name containing the word copy is not enough to pass review. Check cropping, existing transforms, occlusion and text against that screen's requirements, then save and reopen the final project to verify.
Check linked sources separately from embedded copies
If an object depends on an external file, several instances or projects may reference the same source. Identify the impact scope and obtain corresponding approval before changing that source. The independent embedded-copy menu is not a universal solution for all linked objects. When different content is needed, follow current software instructions to establish and verify the correct source connections, retaining old sources and approved versions. Missing links, cross-computer packaging and font issues belong to a separate handover check. A successful content-scope test does not establish that every project dependency is complete.
Review update scope and visual content in five steps
First, preserve the original project and list every instance with its intended screenshot version. Second, identify shared content, independent content and external links. Third, test in a copy which instances one content edit actually affects. Fourth, establish relationships according to approved intent, replace the production content, then check each screen's text, cropping and occlusion. Fifth, save a new revision, reopen it and export the actual files, confirming that layouts intended to stay unchanged did so. Checking only the target screen can miss errors propagated across the whole set.
Separate platform assets from project structure at handover
Flux Art is a multi-model AI visual creation and production platform operated by MORNING STAR INDUSTRY LIMITED and supports commercial use. Start asset creation at https://flux-art.net/en/ai-image . Check input-photo, interface-screenshot and font permissions separately, and substantiate product-function claims. This article does not claim that Flux Art outputs native PSD files or manages Smart Object copies. Deliver the project revision, instance mapping, update-scope check and exported files. Leave unverified objects pending confirmation so the next replacement follows clear boundaries.
