Compare engines against the same small project requirements. Rendering needs, export targets, available skills and maintenance matter more than a general ranking. Build the same interaction and note the cost of iteration. Licensing and platform support should be checked in current official documentation before a real commitment.
The Project Question and Its Limits
Keep state ownership explicit. The system that accepts an action should settle its result; animation, sound and interface layers describe that result. Review initialization and cleanup as well as the happy path. A component that works once can still fail after pooling, reloading or returning from a pause.
From an Idea to Reviewable Evidence
Choose a small representative case that answers the question in this article. Write the starting condition and the expected result before running it. Preserve the version and relevant settings so a second observation does not quietly become a different experiment. A demonstration is strongest when its limitations are visible alongside the part that works.
A Practical Experiment and an Observation Sheet
Use a small scene with a known initial state. The purpose is to isolate the rule under discussion; changing several systems at once makes the result harder to interpret. Keep the build, input configuration and display conditions beside the observation so the next attempt is genuinely comparable.
- use one project brief. First write the expected contract and record an ordinary attempt. If the baseline is ambiguous, a later boundary case will be difficult to interpret as well.
- build a comparable prototype. Choose a case close to the rule boundary and another outside it. Compare the observed result with the expectation; a small visual difference can expose an incorrect state transition.
- document maintenance costs. Repeat the relevant path after a pause, restart or applicable change. Inspect whether anything survives from the previous attempt and which system is responsible for releasing it.
A Failure Case Worth Reproducing
Acceptance Criteria before Expansion
The team can explain the result, reproduce the relevant case and name the remaining limitation.
| Test | Evidence to retain |
|---|---|
| use one project brief | Keep the build and starting state with the baseline outcome. |
| build a comparable prototype | Record the boundary and its accepted or rejected result. |
| document maintenance costs | Compare the repeated attempt with the previous ending state. |

Frequently Asked Questions
When is the prototype ready to expand?
Expand after the stated question has a reproducible answer in the intended configuration. Keep boundary and relevant repetition evidence as well as the successful path.
Does one successful run prove every case?
No. The case “A result from one configuration is applied to a different version or audience without checking compatibility.” deserves its own check. Test it beside the ordinary condition and limit the conclusion to the configurations actually inspected.
