How to Sell Modo 3D Models Online in 2026 — Complete Creator Guide

Foundry Modo produces some of the cleanest hard-surface topology in the industry. Here's how to package, price, and sell your Modo assets online — with 0% commission and in-browser 3D preview.

Published July 22, 2026 · 9 min read

Foundry Modo has earned a reputation as the modeler's modeler. Used by industrial designers at Apple and aerospace firms, game studios like Crystal Dynamics and Sledgehammer Games, and VFX houses across the industry, Modo's edge-weighting system, procedural modeling, and subdivision workflow produce a class of topology that other tools struggle to match. If you build hard-surface props, vehicles, architectural models, or sci-fi assets in Modo, you already have inventory that sells.

This guide covers what Modo assets sell, how to export them for marketplace distribution, how to price at different quality tiers, which platforms give you the best return, and how to protect your work from the file-sharing that plagues 3D asset marketplaces.

What Modo Assets Sell Best

Modo's strength is precision hard-surface work. The asset categories below match that strength against buyer demand — prioritize the high-demand rows for passive income.

Asset Type	Buyer	Demand	Price Range
Game-ready weapon models	Indie game studios, modders	★★★★★	$10–$80
Modular sci-fi / industrial environment kits	Game devs, archviz artists	★★★★★	$25–$150
Architectural furniture & interior assets	Archviz studios, interior designers	★★★★☆	$15–$90
Vehicle models (cars, aircraft, spacecraft)	Game studios, VFX, archviz	★★★★☆	$40–$500+
VFX hero props (hi-poly + LODs)	VFX studios, commercial renderers	★★★☆☆	$50–$300
Mechanical parts & product models	Product designers, engineers	★★★☆☆	$20–$120
LXO source files (Modo-native format)	Other Modo users, studios	★★★☆☆	+30–60% premium

Modular kits consistently outperform individual hero assets for passive income. A modular sci-fi corridor kit with 30 interlocking pieces will continue to sell for years; a single hero prop peaks early. Design kits from day one.

Export Formats for Selling Modo Assets

Modo supports all major export formats natively. Include multiple formats in one ZIP — buyers expect format variety at Modo-quality price points, and it costs you nothing extra.

FBX

Primary — game engines

The standard format for Unity, Unreal Engine, and CryEngine buyers. Export from Modo via File → Export As → FBX. For game assets: set scale to 1.0, apply all deformers, include only the geometry mesh (no subdivision stack), and bake normals into a normal map texture rather than exporting subdivided cage geometry. Include embedded textures or a Textures/ folder alongside the FBX.

GLB / GLTF

Upload as primary — enables 3D preview

Proofly renders GLB files in-browser so buyers can rotate and inspect your model before purchasing. Export GLB from Modo using the glTF Tools for Modo plugin (free, available on Foundry Marketplace) or export FBX and convert using Blender's File → Export → GLTF as a free intermediary step. PBR metallic-roughness materials transfer cleanly through this pipeline. Always upload the GLB as your primary file on Proofly — the in-browser preview is your single best conversion tool.

OBJ + MTL

Universal — render artists

OBJ is the widest-compatibility format and the choice for archviz and rendering buyers using Cinema 4D, Modo itself, 3DS Max, or V-Ray. Export from Modo: File → Export As → Wavefront OBJ, enable "Export UV Maps" and "Save Material File." Include texture PNGs alongside with paths matching the MTL file. For subdivision models, freeze the subdivision before exporting (Mesh → Freeze) or include both the control cage OBJ and a pre-subdivided version.

LXO (Modo Native)

Premium tier — Modo users

Including the original .lxo scene file is the highest-value add-on you can offer. Modo professionals are willing to pay a 30–60% premium for access to your procedural setup, subdivision stack, edge weights, replicators, and shader tree — things that cannot be transferred through any export format. Sell the LXO as a separate "Source File Included" listing tier priced higher than the FBX+OBJ bundle.

Alembic (ABC)

VFX — animated / simulation

For animated props, destruction simulations, or fluid caches — Alembic preserves per-frame geometry changes that FBX cannot. If your Modo scene includes animation or simulation, export an ABC alongside FBX. VFX buyers using Houdini, Nuke, or Maya will specifically request Alembic for these use cases.

Modo Asset Pricing Guide

Modo artists consistently undercharge for their work. The clean topology, precision edge weighting, and production-ready UVs that Modo produces command a premium over equivalent work from other tools. Price on quality and complexity, not on time spent.

Asset	Base	Mid	Premium
Simple prop (box, crate, small tool)	$5	$12	$25
Game-ready weapon (full PBR, baked normals)	$15	$35	$80
Modular environment kit (20–50 pieces)	$25	$60	$150
Furniture / archviz piece	$15	$40	$90
Vehicle (exterior only)	$40	$120	$300
Vehicle (full interior + LODs + animations)	$120	$280	$500+
VFX hero prop (hi-poly + game-ready LODs)	$50	$120	$300
LXO source add-on (Modo procedural setup)	+$20	+$40	+$80

Topology as a Selling Point

Modo's edge-weighting and subdivision workflow produces topology that game artists specifically seek out. Screenshot your wireframe alongside your render — clean quad topology signals professional quality and justifies premium pricing even before buyers open the file.

LOD = Price Multiplier

Including multiple LOD levels (LOD0 hero + LOD1 mid + LOD2 low + LOD3 billboard) is a significant time investment but commands 2–3× the price of a single-mesh asset. Game studios pay a premium for anything that reduces their own asset pipeline work.

Scale Your Kit

Price modular kits at 40–60% of what buyers would pay to buy each piece individually. A 30-piece kit where each piece is worth $5 should price at $60–$90, not $150. The bundle discount drives impulse purchases and increases total revenue per customer.

Multi-Platform Strategy for Modo Creators

Modo assets sell to different buyer pools on different platforms. The most effective approach targets two platforms for broad coverage, then drives traffic from social channels.

Proofly — Primary Catalog (All Asset Types)

List everything here: props, kits, vehicles, archviz pieces, LXO source tiers. GLB files render in-browser so buyers inspect your topology before purchasing — critical for premium Modo assets. 0% commission means every sale returns full price. Enable HiddenMark on all listings so downloads are watermarked against redistribution.

Fab (Epic) — Unreal Engine Game Assets

If your assets are packaged for Unreal Engine (proper LODs, collision meshes, material instances), Fab is the largest single marketplace for UE game assets. The 12.5% commission is the lowest among large platforms. Requires re-packaging your Modo FBX exports into Unreal projects, which takes additional time but unlocks Fab's large indie developer audience.

ArtStation + LinkedIn — Professional Discovery

Post your Modo wireframes and breakdown renders on ArtStation and LinkedIn. The Modo community on ArtStation includes hiring art directors at studios — a portfolio post that goes viral in the professional community generates direct Proofly listing traffic that commission-free platforms cannot provide. Tag posts "#Modo #FoundryModo #HardSurface" to reach the correct audience.

Modo-Specific Tips for Marketable Assets

Freeze edge weights before FBX export: Modo's edge-weighting system does not export through FBX — it is a Modo-native subdivision mechanism. Before exporting, set your subdivision level to the intended output (typically 1–2 for game mesh), then freeze (Mesh → Freeze). This bakes the smooth result into explicit polygons. Alternatively, bake the high-poly normals into a normal map for the low-poly cage — the industry-standard workflow for game assets.

Use Mesh Cleanup before any export: Modo's Mesh Cleanup tool (Mesh → Cleanup → Remove Doubles) eliminates doubled vertices and degenerate polygons that cause issues in game engines. Run it before every export. Check Statistics panel (N) to verify 0 double vertices and 0 non-manifold edges — both will cause import errors in Unity and Unreal.

Bake AO and cavity maps in Modo: Modo's baking system (Texture Bake command) produces high-quality ambient occlusion and cavity maps that significantly improve perceived model quality. Even if buyers will re-bake for their own pipeline, including baked AO as a texture in your ZIP demonstrates production quality. Bake at 4K, include both the PBR set and the AO-baked albedo.

Document procedural setup in README: If your model uses Modo's procedural modeling system (mesh operations, procedural deformers), document which operations are live and how to adjust parameters in your README.txt. This is especially valuable for archviz assets where buyers want to change dimensions — a documented procedural setup justifies the premium LXO tier.

Screenshot the wireframe: Modo produces cleaner topology than almost any other tool. Use this as a marketing asset: include a wireframe render in your product images. Game art directors specifically look for clean quads and correct edge flow — showing your wireframe before they buy builds trust and justifies premium pricing on professional assets.

Test your FBX in Blender before selling: Import your exported FBX into Blender (free) before publishing. Blender will catch missing textures, flipped normals, scale issues (the infamous FBX 100× scale problem), and mesh errors that might be invisible in Modo. If it imports cleanly in Blender, it will import cleanly almost everywhere. Fix any issues before publishing.

Protecting Modo Assets from Piracy

Piracy is a persistent problem for 3D asset sellers. FBX and OBJ files can be freely forwarded once downloaded; there is no file-level DRM that prevents redistribution. Studios particularly suffer from leaked modular kits that circulate on Discord and Telegram channels, often stripped of credit and re-sold elsewhere.

Proofly's HiddenMark system embeds an invisible steganographic watermark directly into the mesh geometry at the vertex level. The watermark is imperceptible visually, survives format conversion (FBX → OBJ → GLB), and persists through most common mesh modifications. If your Modo asset appears on a piracy site or is being distributed without a license, you can scan any extracted mesh to recover the original purchaser ID.

How HiddenMark Works for Modo Creators

Enable HiddenMark on your listing before publishing
Each buyer receives a download with a unique watermark embedded in the mesh
If your asset appears in a piracy channel, download the leaked file
Run the Proofly HiddenMark detection scan — it recovers the purchaser ID from any mesh format
Issue a DMCA takedown identifying the specific leaker by their purchase record

The watermark persists through FBX → OBJ → GLB conversion and basic mesh modifications. It is invisible in any standard rendering pipeline including V-Ray, Arnold, and Unreal Engine.

Writing a Modo Asset Listing That Converts

Professional buyers evaluate quality quickly. Your listing must answer technical questions before they ask — and signal production quality in the first glance.

Title formula: [Style/Use Case] [Asset Type] — [Key Feature], [Format], [Poly Level] | e.g.: "Sci-Fi Corridor Kit — 35 Modular Pieces, Game-Ready, LOD0-LOD3, UE5 + Unity"

State polygon count and LOD levels: "Low poly: 2,800 tris | Mid: 8,400 tris | Hi-poly: 210,000 polys" or "LOD0: 12K, LOD1: 6K, LOD2: 2K, LOD3: 400" tells a technical buyer everything they need to evaluate engine compatibility without opening the file.

List every included format: "Included: GLB, FBX, OBJ + MTL, Textures (4K, PNG: Albedo/Normal/Roughness/Metalness/AO)" — buyers scan for their required format immediately. If it is not listed, they assume it is not included.

Lead with the engine-ready claim: "Game-ready — clean quads, no n-gons, non-overlapping UVs, real-world scale" is the sentence game developers scan for. If your Modo topology qualifies (and it likely does), state it explicitly in the first paragraph.

Include wireframe screenshots: Add a wireframe render to your product images. This is unusual enough that it immediately signals professional quality — most marketplace sellers do not bother. It is also how art directors evaluate whether your topology is actually clean or just looks clean in renders.

State real-world scale: "Real-world scale: 2.1m × 0.8m × 0.9m" for furniture. "1:1 scale, vehicle is 4.2m long" for a car. Buyers drop models straight into scenes — scale mismatches are the most common complaint on 3D asset marketplaces.

Specify license per use case: "Personal/indie (commercial OK) / Studio ($5K+ revenue requires extended license)" prevents license confusion. Use Proofly's built-in license tier system and be explicit about what each tier allows: stream revenue, client deliverables, resale as part of a game, etc.

Step-by-Step: Publish Your First Modo Asset on Proofly

Finalize and clean the mesh in Modo

Run Mesh Cleanup (remove doubles, fix non-manifold edges). Verify UVs are non-overlapping and within 0–1 UV space. Check Statistics panel: 0 double vertices, 0 non-planar polys for game assets. Apply all deformers for export.

Bake textures at 4K

Use Modo's Texture Bake to generate albedo, normal, roughness, metalness, and AO maps at 4K. Save as PNG for lossless quality. Include all maps in a Textures/ folder in your ZIP.

Export FBX, OBJ, and GLB

Export FBX with frozen subdivision and embedded armature if rigged. Export OBJ with MTL. For GLB: export FBX then convert through Blender (free) — import FBX, File → Export → GLTF 2.0, format GLB, include textures. Verify GLB imports correctly in Blender before moving on.

Test FBX in a game engine

Import your FBX into Unreal or Unity (or Blender as a proxy). Check scale (should be 1 unit = 1 cm for Unreal or 1 m for Unity). Verify textures load, normals face outward, and no geometry errors appear. Fix any issues before zipping.

Create renders and wireframe screenshots

Render 3–6 angles including at least one wireframe overlay screenshot. Render in Modo's path tracer or Cycles (via Blender export) for production quality. These images are your primary conversion tools.

Bundle ZIP with README

Structure your ZIP per the bundle guide above. Write a README.txt with poly counts per LOD, texture resolution, UV sets, real-world scale, and which software versions you tested. Clear README = fewer support requests.

Upload to Proofly with HiddenMark enabled

Create a new listing, upload the GLB as primary file (enables in-browser 3D preview), upload the full ZIP as the download package. Enable HiddenMark in listing settings. Write your listing description using the checklist above. Publish.

Frequently Asked Questions

Can I sell Modo models on a 3D marketplace?

Yes. Models created in Foundry Modo can be exported to FBX, OBJ, GLB/GLTF, and Alembic — all standard formats that 3D marketplaces and buyers accept. You export from Modo to a universal format and sell that file; buyers do not need Modo installed to use your model. On Proofly you can also include the original .lxo source file in your download package for buyers who use Modo themselves.

What Modo assets sell best online?

Hard-surface game props (weapons, vehicles, mechanical parts, sci-fi panels) consistently top the sales charts because Modo's edge-weighting and subdivision workflow produces clean, game-ready topology. Architectural visualization assets (furniture, lighting, structural elements) also sell steadily because Modo's procedural modeling and material system makes photorealistic results faster to produce. VFX-ready hero props and environment kits command the highest per-unit prices ($50–$300+) but take more time to create. Accessory and modular kit packs provide reliable passive income — one pack with 20–50 modular pieces often outsells individual hero props.

What file format should I export from Modo for selling?

For game engine buyers: FBX with baked normals and embedded textures is the standard. For archviz and rendering buyers: OBJ + MTL or FBX with PBR materials. For web preview: GLB (upload as the primary file on Proofly — it renders in the browser so buyers can inspect your model before purchasing). For Modo-to-Modo buyers: include the .lxo source file in a premium tier ZIP. Always include multiple formats in one ZIP package — buyers who pay $30–$80 for a prop expect at least FBX + OBJ, and adding GLB costs you nothing but enables the 3D preview.

How much do Modo models sell for?

Single game-ready props (weapons, furniture, small assets) sell for $5–$40 depending on complexity and texture quality. Environment kits (modular sci-fi corridor, rock pack, foliage collection) sell for $20–$120. Hero props with high-poly + game-ready LODs, baked normals, and full PBR textures sell for $40–$300. Archviz furniture or product models sell for $15–$80 per piece. Vehicle models range from $40 (car exterior low-poly) to $500+ (detailed interiors, animated doors). On Proofly you keep 100% of your listed price — the buyer pays a flat $1 service fee, not you.

How do I protect Modo models from piracy?

Standard password-protected ZIPs provide no real protection once a buyer extracts the files. Proofly's HiddenMark system embeds an invisible steganographic watermark directly in the mesh geometry at the vertex level. The mark is imperceptible visually, survives format conversion (FBX → OBJ → GLB), and can be detected in any extracted mesh file. If your model appears on a piracy site or is being redistributed without a license, you can scan the leaked file to recover the original purchaser ID and issue a targeted DMCA takedown.

Where is the best marketplace to sell Modo models?

Proofly offers 0% commission so you keep 100% of every sale, plus an in-browser 3D viewer that lets buyers inspect your model before purchasing — this significantly increases conversion rates for complex hard-surface props. Sketchfab has strong discovery but takes 30% commission. CGTrader takes 30–40% but has a large game-industry audience. TurboSquid takes 40–50% for non-exclusive listings. For the best income per sale on passive products — especially if your models are high-quality niche assets — Proofly's 0% model pays more than any competitor once your listing is established.
