Short answerNo. Click retry on the failed row and it re-runs for free; the unit was already paid for. Re-entering the art gate only lists what is still missing, and if a batch cannot be charged in full, everything is rolled back and nothing is billed.

Generation progress shows three boards: Scenes, Characters (anchor → four-view) and Props & voices. Each row has a lamp: green done, amber rendering, grey queued (props read queued, serial per owner), grey waiting on dep for a four-view whose anchor is not finished, and red with the error text when something failed. The header counts units and voices, and the whole page can be closed and reopened; it polls on its own.
A failed row shows a retry link. It re-fires just that unit. The unit is already in the charged list, so the retry is free; the header meter says so: failed retries are never billed.
If a voice fails, the row reads Voice failed and a note explains that voice generation may be temporarily unavailable or at capacity. Wait a few minutes and retry; if it keeps failing, write to support so we can check capacity. A missing voice never blocks the rest of the pack.
Click a finished row's label to open the images that unit produced, four-views first, then anchors. If an anchor looks wrong, this is the cheapest moment to fix it, before anything renders.
Ready, hand off → unlocks when every row is green. You do not have to wait for deferred rows you never ticked; those are generated during rendering.
