Turn quick iPhone scans into marketplace-ready 3D assets — step-by-step Blender workflow: retopology, PBR baking, LODs, and export tips for 2026.

Turn phone scans into marketplace-ready 3D assets — fast, reliable, and saleable

Struggling to turn casual iPhone scans into something you can sell? You’re not alone. Many creators capture quick scans for personal use (think custom insoles, props, or small objects) and then hit a wall: messy meshes, huge triangle counts, bad UVs, and no idea how to export clean, PBR textures, PBR-ready files that buyers expect in 2026. This guide walks through a real-world workflow — from iPhone photogrammetry to polished, retopologized 3D asset — using Blender + modern tools and marketplace export tips.

The 2026 context: why this matters now

Smartphone scanning is no longer experimental. With LiDAR-equipped iPhones and photogrammetry apps (Polycam, Scaniverse, Apple Object Capture pipelines) improving every year, the barrier to entry is tiny. But marketplaces and buyers have also raised the bar: they expect PBR textures, LODs, efficient UVs, and AR-ready formats (glTF/GLB, USDZ). In late 2025 and into 2026, two trends are decisive for creators:

Mobile capture quality > quality expectations: People expect quick AR previews and web-ready models from casual scans.
AI-assisted retopology & denoising: Tools accelerate cleanup but you still need manual checks for marketplace standards.

Overview: Quick workflow at a glance

Capture: iPhone photogrammetry best practices
Reconstruct: create a dense mesh in Polycam / Object Capture
Clean & decimate: initial cleanup in Blender
Retopology: create a production-quality low-poly mesh
UV unwrap & pack: optimize islands for baking and streaming
Texture bake: high->low PBR baking (normal, AO, albedo, roughness)
LOD & export: create LODs, create glTF/FBX/USDZ packages
Marketplace prep: screenshots, license, readme, formats

1) Capture: iPhone photogrammetry tips for better starting data

Good output starts with good input. When you’re scanning something small like an insole or handheld prop, use these rules:

Use consistent lighting. Avoid harsh shadows—diffuse light (overcast or light tent) is ideal.
High overlap: ~70–80% overlap between frames yields better photogrammetry alignment.
Keep exposure consistent. Lock focus and exposure on the iPhone when possible.
Scan from all angles, including the underside. For objects with cavities, get inside angles too.
Include a scale reference (ruler, coin) or use AR measuring features in apps to set correct real-world scale.
Use markers or a patterned background when texture is low — helps reconstruction.

2) Reconstruct: choose your photogrammetry tool

Options in 2026 include Polycam (mobile + cloud processing), Apple Object Capture (macOS API & RealityKit pipeline), RealityCapture, and cloud services. For creators who want speed and a modest learning curve, Polycam is still the most common start. For batch, high-control workflows and production reconstructions, Object Capture or RealityCapture gives better control.

Export from your photogrammetry tool as OBJ/FBX/PLY with the high-res texture. Expect a dense mesh (often millions of triangles). That’s okay — it’s your high-poly source for baking.

3) Clean & decimate inside Blender (first pass)

Import the dense mesh into Blender (4.x recommended in 2026). Do the following initial cleanup:

Duplicate the original and work on a copy. Keep the raw scan safe.
Go into Edit Mode: Mesh → Clean Up → Merge by Distance (removes tiny dup verts).
Remove non-manifold geometry: Mesh → Clean Up → Delete Loose and fix non-manifold faces.
Use Decimate Modifier for a fast reduce pass—target a manageable polycount (for insoles, 5k–30k tris depending on detail). This is not final topology.
Use the Remesh (Voxel) modifier if your scan is noisy; it produces a cleaner, evenly tessellated surface to retopo from. For heavy cloud processing and batch runs, consider how data-center and cloud pipelines will affect turnaround and cost.

4) Retopology: automatic and manual options

Retopology is where the asset moves from “scan” to “product.” You have three core approaches in Blender:

Automatic Quad Remesh (paid add-ons like QuadRemesher, or the increasingly capable Blender built-in tools): Great for speed and when you need mostly clean quads.
RetopoFlow (industry standard add-on): Best for control — draw quads, guide edge flow, maintain silhouette.
Manual retopo: Use snapping (Face Project) + Shrinkwrap modifier and build edge loops for optimized topology.

Practical tips:

Aim for clean quads where possible — they’re friendlier for UVs and subdivs even if your object is static.
Preserve silhouette: allocate edge loops on silhouette and wear points (for an insole, keep the toe curve crisp).
Target tri/quad counts for marketplaces: many buyers accept 5k–30k triangles for props and small assets. For game engines, prepare LOD0 at 8–16k, LOD1 at 2–8k, LOD2 under 2k.

5) UVs: unwrap like your sale depends on it

Buyers judge quality by how textures look. Good UVs matter more than pretty topology for surface assets.

Use UV Smart Project only as a last resort — for production, manually create islands around logical features.
Maintain consistent texel density. Use Blender’s UV Pack Island with margin to avoid bleeding when baking.
Keep seams in natural transitions (inside curves, under flaps). For insoles, seams along the inner arch work well.
Consider multiple tiling UV sets for micro-details (normal/roughness) and a second set for unique decals if needed.

6) Bake PBR textures: high->low workflow

Baking transfers detail from the dense scan to your optimized mesh. Marketplaces expect a PBR set: Base Color (albedo), Normal, Roughness, Metallic (if applicable), and Ambient Occlusion. You’ll bake these either inside Blender (Cycles) or in a dedicated baker like Marmoset Toolbag, xNormal, or Substance 3D Painter.

Baking in Blender — practical steps

Create image nodes in the low-poly material for each map you will bake (Normal map: 2048 or 4096 px for hero assets; create lower-resolution versions for LOD packages).
Select the low-poly object first, then Shift+Select the high-poly scan (high must be active). In the Render properties choose Cycles for reliable results.
Use the Selected to Active bake option. Enable a cage (or set a Ray Distance) to avoid projection errors.
Bake Normal, then AO, then Diffuse Color (if you want albedo baked). For roughness/metallic, you can paint or derive values in a texturing app.
Export baked images with 16-bit where appropriate, but deliver 8-bit PNGs for most marketplaces to reduce filesize. Keep masters in a lossless format.

Advanced tips:

Use a cage mesh if the geometry is complex; it helps avoid projection artifacts.
Bake with margin (padding) to prevent edge seams when mipmapping streams in-game engines.
For height/displacement, bake a separate height map if buyers ask for it — especially useful for AR physical accuracy.

7) Create LODs & optimize delivery

Most marketplaces and game stores expect multiple LODs. Provide at least 3 LODs and a guide to the polycounts and intended use.

LOD0: Full detail (8k–30k tris depending on asset).
LOD1: Medium (2k–8k tris).
LOD2: Low (500–2k tris).

Generate LODs either by manual retopo or using decimation while baking per-LOD normal maps from the LOD0 high-res surface. Name files clearly: assetName_LOD0.glb, assetName_LOD1.glb, etc.

8) Export formats & marketplace specifics (2026)

Choose formats based on buyer expectations:

glTF/GLB: The best single-file format for web, AR, and PBR compliance. Use glTF 2.0 metallic-roughness workflow. GLB packs textures inside the binary file — great for previews and downloads.
FBX: Widely used in engines (Unity, Unreal). Include textures as external files and a material guide.
USDZ: Required for Apple AR Quick Look and AR commerce. Convert glTF to USDZ (Apple tools or online converters) and check AR scale.
OBJ+MTL: Legacy, but still useful for some customers. It’s not PBR-native so provide accompanying PBR maps.

Recommended texture sizes in 2026:

Hero asset: 4096x4096 for albedo/normal (deliver also 2048/1024 variants)
Web/preview assets: 1024–2048
Provide compressed WebP/PNG previews for gallery thumbnails

9) Packaging for sale: what to include in your downloadable ZIP

Make buying easy and trustworthy — include everything a buyer needs:

glb/glTF (with embedded textures) and FBX/OBJ (texture folders)
Separate texture maps (albedo, normal, roughness, metallic, AO) and PSD/EXR masters if you supply them
LODs with clear file names and recommended polycounts
Preview images: 6–8 high-quality renders, one with wireframe overlay, one with PBR breakdown
Turntable animation MP4 and AR preview (USDZ) if available
Readme and license file: state allowed commercial uses, attribution rules, and whether reselling of assets is permitted

10) Pricing, licensing, and marketplace best practices

Decide your license: common choices are Royalty-Free Commercial, Editorial-Only, or Custom. Be explicit. Marketplaces often require a simple license summary on the listing page.

Presentation sells. Use:

Clean thumbnails and descriptive titles with keywords (e.g., "Insole 3D Scan — PBR, 3 LODs, glTF/FBX")
Detailed description: polycounts, texture sizes, formats, intended use cases
Honesty about source: say it’s an iPhone scan remastered in Blender — many buyers like authenticity

Case study: From iPhone insole scan to a sellable pack (realistic example)

Quick summary of a small project I ran in late 2025:

Capture: 120 photos with Polycam on iPhone 15 Pro Max + LiDAR for depth. Exported OBJ + 8k texture.
High poly: initial mesh was ~3.7 million triangles. Decimate to 500k for a working high-poly using Blender voxel remesh.
Retopo: used RetopoFlow to create a clean 9,600-triangle mesh optimized for shoe interior shapes.
UVs: manual islands, 4096 base color & normal maps baked in Blender Cycles using a cage.
LODs: LOD0 9.6k tris; LOD1 3.2k; LOD2 800. Baked normal maps for all LODs from the high-poly.
Export: glb (embedded textures), FBX (external textures), USDZ for AR preview. Final glb was 32 MB — lean enough for web and AR.
Listing: $12 for single license, $30 for commercial/extended license. Included PSD masters and usage guide.

The asset sold steadily on niche marketplaces because it included AR USDZ, good previews, and clear license terms.

Advanced tips and troubleshooting

Projection artifacts on baking?

Increase cage distance, refine the cage mesh, or reduce ray distance. Check for flipped normals on the high poly.

Seams visible in textures?

Increase texture margin in the bake, or paint seams out in Substance/Photoshop and provide a seam-free albedo as a fallback.

Normal map looks inverted in engine?

Check handedness: DirectX vs OpenGL normal map conventions. Many exporters let you flip green channel. glTF uses OpenGL (Y+).

Legal & ethical notes (2026)

When scanning with a phone, be mindful of rights and privacy. Don’t sell scans that include:

Identifiable likenesses of people without consent
Trademarked logos or copyrighted surface art (unless you hold rights)
Scans of private property where you lack permission to distribute

Label scanned assets clearly if they come from real-world objects. Many buyers want authenticity metadata — include app used, device, and date to improve trust.

2026 predictions: what to expect next

More cloud-assisted photogrammetry pipelines: Faster, cheaper cloud processing will let creators handle batches.
AI-driven retopo and UV packing: Expect near-instant quads and optimal UV packs — but manual touch-ups will remain vital for quality listings.
AR commerce demand: Buyers will increasingly expect USDZ and embedded AR previews in product pages.

“Capture fast, polish intentionally.” — a guiding mantra for creators selling scanned assets in 2026.

Actionable checklist: from iPhone scan to store-ready pack

Capture: 70–80% overlap, diffuse light, scale reference.
Reconstruct: Polycam/Object Capture → export high-res OBJ/FBX.
Import to Blender: duplicate, merge by distance, remove non-manifold.
Decimate/remesh: create a working high-poly for baking.
Retopo: QuadRemesher/RetopoFlow/manual retopo to target tri count.
UVs: manual seam placement, consistent texel density, margin for padding.
Bake: Normals, AO, Albedo, Roughness. Use cage + margin.
Create LODs: at least 3; name them logically.
Export: GLB (embed), FBX, USDZ; include texture packs and PSD masters.
Package: preview images, turntable, readme, license, recommended uses.

Final notes — turn casual scans into extra income

Turning an iPhone scan into a marketplace-ready 3D asset is mostly about process and presentation. The raw capture is just the beginning — careful retopology, thoughtful UVs, clean PBR bakes, and smart packaging turn casual scans into reliable revenue-generating products. With 2026 tools improving capture and AI-assisted helpers speeding repetitive work, your competitive advantage is craftsmanship and presentation.

Ready to start? Try this small task today: take a 60-90 second scan with Polycam, export OBJ, import to Blender, and perform one cleanup + one bake. Build that into a repeatable pipeline and scale up. That first polished asset is closer than you think.
