Lesson 3 of 5
AI Texturing & Material Generation
From the course AI for 3D & Game Assets
Texturing is where AI can dramatically improve the quality of 3D assets. Even if geometry is imperfect, great textures make assets look professional.
AI Texturing Tools
- Meshy AI Texturing — Upload an untextured mesh and describe the material. AI generates UV-mapped textures directly on the model.
- Polycam AI Textures — Generate PBR texture sets (albedo, normal, roughness, metallic) from text descriptions.
- Withpoly — AI-generated seamless textures and materials for 3D work.
- Poly.cam Texture Generator — Create tileable textures from text prompts.
- Adobe Substance 3D Sampler — Uses AI to convert photos into PBR materials.
PBR Textures Explained
Physically Based Rendering (PBR) uses multiple texture maps to create realistic materials:
- Albedo/Diffuse — The base color without lighting
- Normal Map — Surface detail (bumps, grooves) without extra geometry
- Roughness — How shiny or matte the surface is
- Metallic — Whether the surface is metallic or not
- Height/Displacement — Actual geometry deformation for close-up detail
- Ambient Occlusion — Soft shadows in crevices
AI tools can generate all these maps from a single text prompt.
Texturing Workflow with Meshy
- Upload your untextured 3D model (OBJ, FBX, or GLB)
- Click "Texture" and describe the desired material:
- "Weathered medieval stone with moss growing in the cracks"
- "Polished chrome with subtle scratches and fingerprints"
- "Hand-painted cartoon wood texture, Zelda: Wind Waker style"
- AI generates the texture mapped to your model's UVs
- Generate multiple variations and pick the best
- Download the textured model or texture maps separately
Generating Seamless Textures
For environment textures (floors, walls, terrain):
- Use a text-to-texture tool: "Cobblestone path with weeds growing between stones"
- Verify seamlessness — the texture should tile without visible seams
- Generate PBR map variations (normal, roughness, etc.)
- Apply in your game engine or 3D software
Hand-Painted Style Textures
AI excels at stylized textures for non-photorealistic games:
- "Hand-painted fantasy stone wall, World of Warcraft style"
- "Cel-shaded metal armor, anime aesthetic"
- "Watercolor-style grass and dirt ground texture"
These are often higher quality than AI-generated photorealistic textures.
Texture Consistency
For game assets, texture consistency matters:
- Use the same tool and similar prompts for related assets
- Maintain consistent texel density (pixel resolution per unit of surface area)
- Match lighting assumptions across all textures
- Create a texture style guide for your project
Combining AI and Manual Texturing
The best results come from combining approaches:
- Generate base textures with AI
- Import into Substance Painter or Blender
- Add hand-painted details, wear patterns, and unique elements
- Adjust PBR values for your specific lighting setup
- Bake final maps at your target resolution
Key Takeaways
- •AI can generate complete PBR texture sets (albedo, normal, roughness, metallic) from text
- •Meshy's AI texturing applies materials directly to uploaded 3D models
- •Stylized/hand-painted textures often turn out better than photorealistic AI textures
- •Maintain texture consistency across assets with similar prompts and tools
- •Combine AI-generated base textures with manual refinement for best results
