3D Graphics — Side-by-Side Results
Prompt
"Photorealistic 3D render (Blender/Unreal Engine aesthetic) of a mid-20s woman with shoulder-length wavy brown hair in a cozy oversized hoodie and bike shorts, holding her phone slightly above eye level for a casual front-camera selfie while glancing near the lens with a half-smile. She’s sitting at a small window-side café table with an iced latte and a messy tote bag, candid “quick check-in” vibe, a few people softly blurred in the background. Natural morning window light with subtle volumetric rays, subsurface scattering on skin, physically-based materials on the glass cup and knit fabric, slight handheld framing like an Instagram story."

Flux Ultra 1.1 Strengths
- Exceptional micro-detail for 3D surfaces (materials, pores, scratches, fabric weave, brushed metal)
- Photorealistic CGI look with strong lighting and shadow definition for product and environment renders
- Premium, polished output that often needs fewer re-rolls to reach a “final render” feel
- Strong at high-impact hero images where realism and clarity matter most
Seedream 4.5 Strengths
- Image-to-image editing for iterating on an established 3D look (pose, framing, palette, prop swaps)
- Versatile styles for 3D graphics—clean product CGI, stylized renders, and digital art variations
- High-resolution output suitable for detailed scene exploration and concept directions
- Efficient workflow for art direction: generate, then refine without restarting from scratch
Verdict
If your priority is premium photorealistic 3D renders—especially close-up product CGI, realistic materials, and crisp lighting—Flux Ultra 1.1 is the stronger pick for “final-looking” images.
If your 3D workflow depends on revisions and controlled iteration (e.g., evolving a scene layout, reworking an existing render, or exploring multiple stylizations), Seedream 4.5’s editing capability and style flexibility make it the better day-to-day production choice—at the same 16 credits per image.
