The cannon became our stress test for 3D quality because metallic curves expose shading issues fast. We focused on visible output quality, especially in closeups where rough highlights and seams are most noticeable to end users.
what users were seeing
In some generated cannon outputs, curved metallic regions looked uneven under light. That made otherwise strong models feel low quality in product shots and portfolio renders, even when the silhouette was good.

Before
After
Issue: The curved barrel surface showed hard lighting bands that made the metal look faceted instead of smooth.
Improvement: Highlight flow is now much cleaner, so the barrel reads like metal instead of segmented plastic.
Before
After
Issue: The muzzle rings had abrupt shading breaks that became obvious in closeups and dramatic lighting.
Improvement: Close-range shots now hold together better, with fewer distracting seam artifacts.
what changed
The updated pipeline prioritizes smoother lighting response on curved surfaces, which makes metallic assets look far more stable in showcase renders and app previews.
