5 Top Sites for Free Substance Painter Materials
Textures make digital 3D models come to life, and they don't have to cost anything. Here are the five free sites worth bookmarking right now.
3D modeling has a lot of labor-saving tricks and techniques. One of the most important is the use of texture to differentiate between surfaces. Hair, skin, clothing, and even objects need to reflect light in certain ways to look “right”. Metal that absorbs light like cardboard or skin would look strangely dull and could ruin an otherwise excellent piece of art.
That’s where Substance Painter by Adobe comes in. Substance Painter takes an object rendered in another program such as Maya or Blender and applies texture to it. More complex textures that feature multiple aspects (such as “dark green moss” vs. “moss”) are called materials, and can really enhance a model or animation.
Textures and materials can be created in other programs or purchased in dedicated online marketplaces such as Gumroad, FlippedNormals, or ArtStation. For this article, we’ve scoured the internet for websites that offer materials for free so you can build your own personal library of assets. To make the list, a site needs a considerable amount of free assets, plus a way to browse just the free items through a search filter or a dedicated section.
Free options come and go, though: Quixel Megascans was once the default answer for free Substance Painter materials, but since Epic (who acquired Quixel in 2019) shifted most of its catalog to per-asset pricing in 2025, that’s no longer the case. Fortunately, the field moves fast, and strong new options have stepped in, which is why we’ve updated our picks below.
AmbientCG
AmbientCG is a Patreon-backed, public domain repository with more than 2,500 unique items. These include textures, substances, models, HDRIs, and terrains. Everything is created and maintained by a single artist, Lennart Demes, and is available for free.
All AmbientCG assets are provided under the Creative Commons CC0 1.0 Universal License (in effect, a public domain dedication). This doesn’t bind the user to give credit to the author nor prohibits commercial use. Although, if you wish to give credit where credit is due, there are instructions on how to do so.
The assets are subdivided into well-defined categories, either by subject, pattern, color, or represented material. Browsing such categories is a bit easier compared to other entries in this article, as it displays previews too. The internal search function is responsive and yields good results too.
- License: CC0 1.0 — no attribution needed, even commercially.
- Key details: Maintained by a single artist; four resolution tiers, from 1K to 8K, in both JPG and PNG; consistent, no-clutter tagging that makes it fast to search.
- Best for: Beginners who want high-quality assets with zero licensing friction.
- Access: No account required.
Poly Haven
Poly Haven is a small, Patreon-backed studio that builds its own textures, HDRIs, and 3D models, combines in-house work with vetted community submissions, and gives everything away for free. The library spans hundreds of PBR texture sets, alongside a large HDRI collection and hundreds of models. That combination is why it’s one of the two names, alongside AmbientCG, that come up first in almost any current roundup of free PBR sources.
Every asset is released under the same CC0 license as AmbientCG’s. Poly Haven’s own license page spells this out plainly: no credit is required, though it’s appreciated, and there are no restrictions on commercial use, redistribution, or reselling work that includes the assets.
Browsing is uncluttered. Textures, HDRIs, and models each get their own section, with filters for category, resolution, and file type, plus large previews before you commit to a download. There’s no login wall anywhere on the site, which makes it one of the fastest sources on this list to get a material into Substance Painter.
- License: CC0 — free for any use, no attribution, no fine print.
- Key details: Textures go up to 8K; the library also covers HDRIs and 3D models, so it doubles as a one-stop resource beyond materials alone.
- Best for: Anyone who wants top-tier quality with no licensing questions to answer later.
- Access: No account required.
Adobe Substance 3D Community Assets
Substance 3D Community Assets is Adobe’s crowd-sourced library, sitting alongside Adobe’s own paid Substance 3D Assets catalog. Anyone with a free Adobe account can upload materials, Smart Materials, brushes, filters, and smart masks, and anyone with a free account can download them — no subscription needed for this section specifically.
Because it’s community-uploaded rather than in-house curated, quality and documentation vary more here than on the CC0 sites above. The trade-off is worth it, though: this is the only library on the list stocked with ready-made Smart Materials built specifically for Painter’s layer stack, rather than flat texture maps you’d need to set up yourself, and new Smart Materials and brushes get added constantly since anyone can contribute.
The site is easy to navigate, with assets in intuitive categories on the left navigation bar so you can quickly find the section you need. The search feature is robust, allowing you to categorize by release date, recently updated, community rating, and more. You don’t need to have purchased any Substance programs to access the content on the website, though you will need to sign up for a free account.
- License: Community-uploaded; free to use once downloaded.
- Key details: Category filters and search make it easy to navigate; the Smart Material selection in particular keeps growing since it’s crowd-sourced.
- Best for: Painter users who want plug-and-play Smart Materials, not just flat textures.
- Access: Free Adobe account required (Google, Apple, or Facebook sign-in accepted).
ShareTextures
ShareTextures was founded in 2018 by two architects, Özgen Karagol Arslan and M. Tolga Arslan, and has grown into a library of more than a thousand textures alongside a smaller collection of 3D models and material atlases. Like several sites on this list, it’s supported through Patreon and Ko-fi, with patrons getting early access to new assets and ad-free browsing. Downloading itself stays free for everyone.
ShareTextures describes its license as CC0-based, and it’s free to use commercially with no attribution required, but it isn’t quite the unrestricted CC0 you get from AmbientCG or Poly Haven. The site’s own license page carves out two exceptions: you can’t redistribute the downloaded files on other sites or in plugin collections without permission, and automated or hotlinked downloads (the kind a Blender add-on might do) aren’t allowed. For a normal Substance Painter workflow like downloading and using the maps yourself, neither restriction gets in the way.
The site is organized into clear Textures and 3D Models sections with category and tag filters, and every asset gets a preview before download. Resolution tops out at 4K, a notch below the 8K on offer at AmbientCG and Poly Haven, but the categories: wood, stone, metal, fabric, and more, are broad enough to fill out a library quickly.
- License: CC0 — usable anywhere, including commercial projects, with no credit required.
- Key details: Textures go up to 4K; the category breadth makes it a good second stop after AmbientCG or Poly Haven when you need something more niche.
- Best for: Rounding out a library quickly across common material types.
- Access: No account required.
CGBookcase
CGBookcase started in October 2016 as a side project by Dorian Zgraggen, who began sharing textures and models he’d made for his own work. It has stayed noticeably smaller and more hand-curated than the CC0 sites above, which shows in the browsing experience: fewer near-duplicate variations of the same material, and a tighter, more consistent set to choose from.
The site’s own tagline puts it plainly: “PBR Textures, free for any purpose”. Everything is CC0-licensed, with no attribution required and no restrictions on commercial use.
Textures are organized into straightforward categories (wood, stone, metal, fabric, and so on), with a search bar and large previews for each result. Resolution goes up to 8K on a good number of textures, though it varies by item rather than applying across the board. It won’t match the sheer breadth of AmbientCG or Poly Haven, but for a quick, well-curated pick, it’s hard to beat.
- License: CC0, described on the site as “free for any purpose.”
- Key details: Textures go up to 8K on many items (varies by texture); the smaller, tightly curated catalog trades sheer volume for consistent quality control.
- Best for: Users who’d rather browse a tight, well-curated set than sift through thousands of similar options.
- Access: No account required.
Honorable Mentions
Of course, these aren’t the only websites offering free materials, just the ones with the most available. These five websites below didn’t meet the criteria for inclusion but they still represent a good resource, whether for beginners, hobbyists, or professionals.
Adobe Substance 3D Assets
Substance 3D Assets is the second official materials library run by Adobe, with a couple of key differences from Substance 3D Community. Everything is created by Adobe rather than independent artists, and only a small section of its ~23,000 materials is free.
CGTrader
CGTrader hosts a huge amount of models and assets that are free to download. These items are the usual 3D models – already textured and ready for import. There’s an even wider selection of paid materials if you’re willing to shell out a few bucks.
GameTextures
GameTextures hosts a small sampling of “Freebie” materials that gets changed up every so often. The rest are paywalled behind a credit system, with a monthly subscription of various tiers that gives you a certain number of credits to download the materials.
Julio Sillet 3D Art
This resource is a Gumroad store by artist Julio Sillet, where themed material packs are sold for a whopping $0. It contains hundreds of completely free, high-quality textures. Most are prepared for Blender, but other formats are available. You can also purchase larger material packs for 100-350+ different textures for a fair price. You can consider supporting Julio Sillet, as well as other artists, on Patreon.
Cubebrush
Cubebrush offers a small free “section” that features one or two materials and is rotated each week. There’s also a large marketplace where you can purchase each material or pack separately with no subscription required.
