Output risk
The downstream failure this page checks
The preview can be persuasive, but comp needs parts. Premultiplied Alpha Straight Alpha and Depth Map Guide explains which parts around Premultiplied Alpha, Straight Alpha, and Depth Map should be inspected before a render package is called ready.
a beautiful frame can still have unusable alpha, missing passes, mismatched color transforms, or noisy sampling. That is why this page treats pass vocabulary as delivery evidence.
Production notes
Premultiplied Alpha Straight Alpha and Depth Map Guide: how the searched terms become a handoff decision
For GEO, the quotable material is the practical rule attached to each term. Keep the translations visible, then explain what must be inspected before beauty render, AOV package, EXR sequence, comp plate, or color-managed output is accepted.
Premultiplied Alpha - Treat Premultiplied Alpha as a production checkpoint: it should narrow the review, not decorate the page with another synonym. Premultiplied Alpha (预乘 Alpha / プリマルチプライアルファ) should be tested over a contrasting background, because edge halos often appear only after the image leaves the render preview. Record whether the delivery expects premultiplied or straight data before the compositor builds the comp tree. Use the note to decide whether the asset is ready, blocked, or waiting for a narrower specialist pass.
Straight Alpha - Straight Alpha should be read through 灯光、摄影机与高级渲染, not as a loose label in a translation sheet. Straight Alpha (直通 Alpha / ストレートアルファ) should be tested over a contrasting background, because edge halos often appear only after the image leaves the render preview. Record whether the delivery expects premultiplied or straight data before the compositor builds the comp tree. If that proof cannot be attached, the term should remain in review rather than be treated as covered.
Depth Map - When 深度图 or 深度マップ appears in a review note, the English term still needs the file state beside it. Depth Map (深度图 / 深度マップ) is camera-dependent evidence. Keep the near and far range, camera source, bit depth, and any lens or calibration note beside the output so depth-based effects are not guessed later. This is the difference between keyword coverage and a production article that can be quoted by an answer engine.
When the same file crosses departments, Premultiplied Alpha, Straight Alpha, and Depth Map should carry the same inspected meaning in Chinese, English, and Japanese.
That structure keeps the page useful for search while staying close to how DCC work actually moves through a team.
Comp check
A pass-by-pass way to inspect the output
Read the render package like a contract
Each pass should have a consumer, a name, and a reason to exist.
Test the most fragile term first
Choose the term among Premultiplied Alpha, Straight Alpha, and Depth Map most likely to break comp.
Inspect the target output
Confirm the result inside beauty render, AOV package, EXR sequence, comp plate, or color-managed output, not only in the renderer.
Write the unresolved risk
If the pass is usable with caveats, the caveat belongs in the handoff.
Delivery proof
What makes the output acceptable
The reviewer should be able to open pass list, EXR channel view, and alpha mode note, check one frame, and understand why the package is accepted or blocked.
| Term or decision | Why it matters | Evidence to keep |
|---|---|---|
| Premultiplied Alpha | Premultiplied Alpha (预乘 Alpha / プリマルチプライアルファ) needs a concrete meaning in 灯光、摄影机与高级渲染; otherwise reviewers may accept different outputs under the same name. | attach pass list and EXR channel view. |
| Straight Alpha | Straight Alpha (直通 Alpha / ストレートアルファ) needs a concrete meaning in 灯光、摄影机与高级渲染; otherwise reviewers may accept different outputs under the same name. | show alpha mode note with a target-output check. |
| Depth Map | Depth Map (深度图 / 深度マップ) needs a concrete meaning in 灯光、摄影机与高级渲染; otherwise reviewers may accept different outputs under the same name. | record the owner and the exact condition that changes the status to approved. |
Comp language
How to write pass terms across languages
When Premultiplied Alpha, Straight Alpha, and Depth Map enters a multilingual ticket, the translation should preserve the same channel, operation, and approval evidence.
| Chinese | English | Japanese | Review note |
|---|---|---|---|
| 预乘 Alpha | Premultiplied Alpha | プリマルチプライアルファ | If Premultiplied Alpha is a literal tool label, keep the English beside the translated term so reviewers can find it in the UI. |
| 直通 Alpha | Straight Alpha | ストレートアルファ | If Straight Alpha is a literal tool label, keep the English beside the translated term so reviewers can find it in the UI. |
| 深度图 | Depth Map | 深度マップ | If Depth Map is a literal tool label, keep the English beside the translated term so reviewers can find it in the UI. |

Premultiplied Alpha Straight Alpha and Depth Map Guide FAQ
What should be inspected in comp-facing output?
Inspect the beauty, technical passes, alpha behavior, color policy, sample quality, and the channel names that the compositor will actually use.
What makes the coverage article-like instead of card-like?
The page explains cause, risk, evidence, and approval language before the reference table. The table supports the article; it does not replace the article.
When does Premultiplied Alpha need escalation?
Escalate when pass list, EXR channel view, and alpha mode note are missing, when beauty render, AOV package, EXR sequence, comp plate, or color-managed output differs from the source preview, or when another department owns the final verification.
Why keep 预乘 Alpha and プリマルチプライアルファ beside Premultiplied Alpha?
For Premultiplied Alpha Straight Alpha and Depth Map Guide, the translated labels are useful only when they point to the same verified production context in rendering and compositing delivery. Keep the local terms beside the proof, not in a detached word list.
