When
You need several visual directions for a prop or character before selecting one.
Then
Keep an AI generator such as Meshy in the evaluation.
The useful comparison is how each candidate handles the same subject and how much of each result survives the next production step. Record the prompt or source image, examine multiple views, and reject a result that only looks convincing from one angle.
When
You must meet a specific silhouette, mesh structure, or material setup.
Then
Put Blender or another hands-on modeling application at the center of the workflow.
Direct editing lets you fix requirements that a generated preview cannot verify. You can still use a generated asset as reference or a rough starting point, but budget for rebuilding parts that do not meet the brief.
When
You like AI-first exploration but suspect another service may suit your subjects better.
Then
Test a second generator alongside Meshy before migrating.
Use the same reference and judge both outputs in the same viewer or project. Check geometry, texture alignment, import behavior, and the current usage terms separately; a different visual style is not, by itself, a better production fit.
