A sunlit render may be arranged to reveal a facade clearly, or it may depict a specified place, date and time. Decide which task is being commissioned. The same attractive image should not drift between those purposes without review.
For a construction client, this is an input and scope decision. A visualisation can illustrate a supplied solar scenario, but the image alone does not establish daylight performance, planning acceptability or a validated shadow assessment. Those purposes require the appropriate qualified process.
State whether the sun is being directed or located
An art-directed presentation may choose sunlight for composition and surface readability. If that is the purpose, do not attach a precise seasonal or time-based claim later simply because the result looks plausible.
A documented scenario needs an authoritative set of inputs. Ask the project owner to supply the location, orientation, date, time and time-zone basis, including any relevant daylight-saving treatment. The visual specialist should not guess the project's north from the way a model happens to open.
Epic's Sun and Sky documentation exposes location, north-offset, date and time-zone controls. These are authored inputs, not facts inferred automatically from an attractive building model.
Keep the two review questions separate
For presentation lighting, review whether the image serves the approved architectural explanation. For a supplied scenario, first confirm that the intended inputs have been used and that relevant geometry is present. Then review how the resulting image communicates the limited scenario.
Ask what the scene omits. Neighbouring structures, terrain or shading elements may affect a represented shadow. The film team should not silently supply missing context or imply that a visually detailed project model contains everything needed for a technical assessment.
If a requested artistic adjustment conflicts with the supplied scenario, make a decision rather than blending the two. A second presentation image may be appropriate. Alternatively, keep the scenario unchanged and explain why it looks different from the preferred marketing frame.
An invented facade request
A hypothetical contractor asks for a modelled facade image with light across a recessed entrance. Later, a reviewer wants the same image described as a winter-morning condition. The original sun was placed for readability, not from approved project inputs.
The buyer commissions a separate, clearly bounded scenario using information supplied by the responsible designer, or removes the time-based description. The production does not reverse-engineer convenient inputs to justify the existing image. This invented example illustrates scope control, not solar-analysis practice.
Keep the scenario record with the image
Retain the supplied input set, model identity and relevant omissions beside the approved asset. If the building rotates within the visual scene or contextual geometry changes, the scene should be checked again before the time-based description is reused.
For an animation spanning several times, identify which states are actually represented and how the film compresses them. Do not let a continuous-looking sun movement imply an assessment beyond the supplied purpose. The responsible subject owner should approve the wording and the intended use of any scenario output.
Ask Live Images about the visual explanation and identify any separately required specialist assessment at the outset. Confirm whether the film needs presentation lighting, a supplied scenario illustration or both, without assuming that animation includes solar consulting.
