Texture Generation

1. Install ComfyUI via Stability Matrix.
2. ComfyUI Manager → Install Models → "flux1-dev" (23 GB) or "sdxl-base" (7 GB) for lighter weight.
3. Texture workflow: use ControlNet (tile/UV map) to generate seamless textures.
   • For seamless tiling: ComfyUI has a "Seamless Tile" node that modifies the latent to wrap at edges.
   • Prompt: "PBR brick wall texture, diffuse map, red clay bricks with mortar, seamless, square, 2048x2048, photorealistic, flat lighting, no shadows, top-down view."
   • Resolution: 1024×1024 (upscale to 2048 with ESRGAN).
4. For material texture sets (PBR): generate base color → use ComfyUI workflows to derive normal map, roughness, metallic, height from the base color (using filter nodes, not AI — the derived maps are mathematical transforms).
5. First seamless texture in 8-20 seconds on 12+ GB GPU.
6. For 3D model texturing: export the UV layout from Blender → paint in ComfyUI using the UV map as a ControlNet input → the model respects UV islands.

Used RTX 3060 12 GB ($200-250, see /hardware/rtx-3060-12gb). Runs SDXL for seamless textures at 1024×1024 in 8-15 seconds. Flux at FP8 (12 GB) for higher-quality textures at 20-35 seconds. For a game dev generating 200 textures for a project: batch process overnight — 200 textures in ~1-2 hours. Pair with Ryzen 5 5600 + 32 GB DDR4 + 1TB NVMe. Total: ~$390-440. Texture generation at $400 is production-viable for indie game development. The seamlessness filter + tile preview in ComfyUI ensures textures wrap without visible edges.

Used RTX 3090 24 GB ($700-900, see /hardware/rtx-3090). Runs Flux Dev at FP16 for highest-quality PBR textures at 10-20 seconds per 1024×1024. Can batch-generate entire material sets (base color + normal + roughness) simultaneously via ComfyUI's batch processing. For a professional game studio or archviz firm: one RTX 3090 generates 500+ textures/day. Total: ~$1,800-2,200. For the fastest texture iteration: RTX 4090 ($2,000) at 3-6 seconds per Flux texture. Texture generation is much faster than full-scene generation — the tile/UV constraints make the model's job easier.

The mistake: Generating a beautiful brick texture, seeing it tiles seamlessly in the ComfyUI preview, then applying it to a large wall in a game engine — only to discover obvious repeating patterns every 2 meters. Why it fails: Seamless tiling eliminates visible edges, but the internal pattern still repeats. A single 1024×1024 brick texture tiled across a 10-meter wall reveals identical brick placements, identical cracks, identical color variations — the human eye detects pattern repetition instantly. The fix: Generate multiple variations of the same material (5-10 textures with the same prompt but different seeds). In-engine, randomly blend/rotate/scale the variants to break up repetition. Or: generate a larger texture (4096×4096 via upscaling + inpainting variations). Or: use a material shader that blends multiple textures procedurally. Seamless ≠ non-repeating. Seamless = no visible edge; non-repeating requires multiple variants blended procedurally.
