Repair with masks
Open the mask editor
In Studio, select a drawn panel and choose “Fix a part”, next to “Redraw”; the mask editor opens so you can paint the part you want repainted. With Advanced mode on (Settings › Preferences, or the “Advanced” switch at the top of Studio), the same editor also opens for “Swap a character”, “New background”, “Remove an object” and “Swap an object”, which you’ll find under “More image tools”. Mask tools are part of the Creator and Studio plans.
Paint what may change
Paint the area that may change; everything else is protected. The blue guide shows what’s editable. “Add” paints and “Erase” removes paint. “Brush” sets the size from 4 to 120 (default 52), and “Hardness” sets how soft the edge is, from 0 to 100 (default 80). “Invert” swaps the painted and protected areas, and “Clear” starts again. “Overlay” only changes how strong the blue guide looks. You can paint only inside the panel’s visible crop, and an empty mask can’t be submitted. Describe the change in “What should change?”, then submit.
What the mask guarantees
After the new image is generated, ComicWave copies every pixel outside the painted area from the original and checks that each protected pixel matches exactly. If any protected pixel differs, the job fails: no new version is created and the held credits are released. With a soft brush, faint edges stay protected, while stronger edges blend new and original pixels, always inside the painted area.
Replacing a character
“Swap a character” also asks which character to paint in. Pick an approved or locked character that has a Must match face or full-body reference in Cast; if none qualifies, the editor asks you to lock a reference in Cast first.
What it costs
Mask tools run at Standard quality and hold 15 credits while the job runs. The button reads “Fix a part · 15 credits”; with Advanced mode on, the footer also shows how much of the visible crop is editable and the button reads “Submit repair · 15 cr”. You pay for a finished new version; a failed job releases the hold.
Review the result
Each result becomes a new version of the panel. With Advanced mode off, a finished result is kept on the page automatically, and earlier versions stay under “Other versions”, where “Restore” goes back to one. With Advanced mode on, the versions list offers “Accept” to use a result and “Reject” with a reason or correction note, and “Compare versions” shows the old and new versions side by side or with a slider.
When Describe a change is the better tool
“Describe a change” (the Revise tool) changes one described thing across the whole panel without a mask, so keeping the rest of the panel is an instruction to the model rather than a pixel check. Use it when the change affects the whole panel, when the area is hard to paint, or when you want Draft (9 credits) or Final (45 credits) quality instead of Standard. It’s also available on Starter, which doesn’t include mask tools. Use a mask when the surrounding pixels must not change at all.
