What happens if a render comes out wrong?
It depends what is wrong. If the take misses on camera, light or mood, regenerate: same product, same brief, a fresh take. If your product itself drifted from your photo, report the render instead: an automatic check compares the two and returns that render's credits when it finds drift. A render that fails outright offers a plain retry.
Last reviewed — this answer is checked by hand, not regenerated on deploy.
Generative rendering is not deterministic, and pretending otherwise would set the wrong expectation. Some takes miss — a camera move that hides the label, a set that fights the product, a grade that flattens a colour you care about. The design assumption here is that you will regenerate sometimes, so regenerating is one button rather than a support ticket.
Three failure modes, three different fixes
A render that finishes but is not right is usually a taste problem: watch it, press regenerate, and Nitaris shoots the product again. You can also change the mood first, which usually does more than a reroll on the same brief. Every regenerate is a new render, and it is charged.
A render where the product itself has changed is not a taste problem, and regenerating is the wrong button for it. If a letter in your logo is different, a cap or clasp has been redrawn, a finish has turned glossy or a colour has shifted, press Report issue on that render, in the web studio or the Shopify app, and say in a sentence what does not match. An automatic check compares the render with your reference photo. If the product drifted, that render's credits go back to your balance. It works per render, so one wrong still in a set returns one still's credits, and you can report a paid render for 30 days. Complaints about the angle, the lighting, the background, the crop or general taste are outside the check: they are passed to the team as feedback rather than returned as credits.
A render that fails outright is a technical problem: the app says so plainly and offers a retry.
Why the free preview comes first
This is also the argument for looking at the free preview first. It is your own product, filmed, before you have spent anything — the cheapest possible moment to discover that you want a different treatment.
