Hi everyone,
I built Storefront Studio, a Unity Editor extension for managing the repetitive process of creating game artwork for multiple storefronts and image dimensions.
Instead of repeatedly capturing images, switching to another application, recreating layouts, and checking every output separately, Storefront Studio keeps the complete workflow inside Unity:
Capture > Compose > Validate > Export
Available now on itch.io:

Available now on Fab:

The Unity Asset Store is currently pending review.
Capture
Capture images from:
Game View
Scene View
An offscreen camera at custom dimensions
The Capture workspace includes crop-area guidance, multiple overlays, custom overlay positioning, and PNG or JPEG output.
Captures are stored inside the Unity project and remain available through the Capture Library for reuse in later compositions.
Insert the Capture screenshot here:

Compose
The Composer supports:
Multiple artwork and text layers
Logos, headlines, and taglines
Direct canvas movement, resizing, and rotation
Independent X/Y scaling
Negative scaling for mirroring
Optional center and element snapping
Exact Inspector controls
Shared settings and per-output overrides
Undo, Redo, saved compositions, and session recovery

I would be interested to hear from developers who have prepared store pages before:
Which storefront dimensions or validation checks create the most repetitive work in your release pipeline?
Feedback about additional presets and workflow improvements would be very helpful for future updates.
Thanks for taking a look!
