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.
