Jewelry 3D models often appear grainy in marketing due to low rendering resolution, excessive file compression, or insufficient anti-aliasing.
- Low resolution: Fails to capture fine details like gem facets or metal textures, leading to pixelation. - Over-compression: Common for web/social media, it strips pixel data and blurs sharp edges. - Missing anti-aliasing: Leaves jagged lines (aliasing) that look grainy, especially on curved surfaces.
For clearer results, render at 1920x1080+ resolution, use lossless formats (e.g., PNG) for static images, and enable anti-aliasing in your 3D software before exporting.
