Prompt optimization tips

  1. Specify editability

    State which objects must remain separate, named and editable; otherwise a visually convincing shell may still be unusable.

  2. Close the test loop

    Ask the model to run the scene, inspect visible failures and repeat until concrete frame-rate, interaction and layout checks pass.

  3. Stage long builds

    For large worlds, split the work into districts, assemblies or milestones and approve each section before expanding scope.
