Give every architectural render comment a view identifier, source revision, location and requested decision. Separate design changes from rendering corrections and presentation preferences. This lets the team route the issue to the right owner and verify the revision against the original request.
“Make it warmer” and “the entrance material is wrong” are not equivalent instructions. One may concern image treatment; the other may require a different design source or material assignment.
Identify the image being reviewed
Use stable view names and visible revision information in the review package. Preserve the exact file reviewed, including its hash where practical. A markup attached to an old export should not silently become an instruction on a newer building model.
The visualization brief establishes the intended decision and deliverables. Bring that purpose into the review so comments do not drift into unpriced new views or unrelated design work.
Classify the issue before assigning it
| Issue class | Example | Likely decision needed |
|---|---|---|
| Source design | Opening position differs from the accepted design | Confirm the correct model revision |
| Material assignment | Wrong product on a named region | Confirm mapping and reference |
| Scene or render | Context or image treatment obscures a feature | Correct presentation conditions |
| New requirement | Additional viewpoint requested | Agree added scope and schedule |
Chaos’s CAD rendering workflow separates source preparation from later visualization work.1 Use that distinction to avoid asking a renderer to improvise a design decision that belongs upstream.
Write a reproducible instruction
Name the view and region, describe the observed discrepancy, link the intended reference and request an action or decision. “View EXT-03, entrance soffit: compare with finish schedule revision C; confirm whether the current wood assignment should change” is more useful than “entrance wrong.”
If two reviewers disagree, record the conflict and its decision owner. Do not apply both comments sequentially and call the latest image approved. Resolve the underlying design or presentation choice first.
Retest the exact concern
Keep the original issue visible in the revision record. After correction, compare the same view and region under the relevant conditions. Note whether the requested change solved the concern or exposed a different dependency.
If geometry changed, identify other affected cameras and schedules. If only exposure changed, check that it did not obscure a material comparison. The facade comparison guide explains why observation consistency matters.
Close issues with evidence
Use the comment ledger to connect each issue to an owner, revised output and receiving conclusion. “File sent” is a delivery event; “reviewed and accepted for the stated purpose” is a different event. Preserve both when they matter to the handoff.
The Rendora architecture entry supports the relevant project workflow. Keep review evidence tied to the configuration and output being discussed so an updated source cannot inherit an unrelated approval.
Should every preference become a new issue?
Record preferences that change the accepted output or scope. Consolidate exploratory comments before issuing production instructions, while retaining any unresolved decision that could block release.
