Maliyet:
- AI generation: $20 / ay
- Manual asset: $50-200 / prop
- 50 prop = $2500-10000 → $20
"

Limitasyonlar

AI 3D weakness 2026:

- Multi-character scene (overlap problem)
- Fine detail (vs ZBrush)
- Topology quality (auto = bad)
- Animation rig (manual still)
- Material physics (procedural eksik)
- Industrial CAD (mechanical precision)
- Architectural complex
- Hard surface clean topology

Pro Workflow

Pro 3D artist 2026:

1. Concept (sketch + AI)
2. Base mesh (AI generation)
3. Sculpting (ZBrush manual)
4. Retopology (manual)
5. UV (AI assist)
6. Texture (AI + manual)
7. Rigging (Mixamo / manual)
8. Animation (manual + AI assist)
9. Lighting (manual)
10. Render

Workflow shifted: AI early stages, manual mid-end.
Time savings: %40-60.

Lisans / Telif

• Tripo / Meshy: paid tier ticari OK
• Open source models: lisans değişken
• Reference image telifli: ihlal risk
• Game asset marketplace: AI disclosure değişken
• NFT: telif sorunu (training data debate)

Yaygın Hatalar

1. Topology ignore: AI mesh → animation fail
2. High polygon production: optimize yok
3. No retopology: Game performance kötü
4. Generic prompt: ‘cool sword’ → bad
5. Single angle reference: 360 view eksik
6. Texture auto kabul: PBR maps eksik bazen

Özet

AI 3D 2026 = prototype 5 dakika. Tripo + Meshy + Blender = solo creator stack. Game asset, 3D print, AR/VR, web 3D — hepsi hızlandı. Anahtar: AI mesh + manual cleanup. Pro detay = ZBrush hala üst tier.
