CC0 vs CC-BY vs Royalty-Free: What You Can Actually Use Commercially

6/24/2026 · 6 min read

The short version: CC0 means do anything, no attribution required; CC-BY means do anything, but credit the author; royalty-free is where "free" often really means "free, but with conditions" — and you have to read the specific license, not the banner. For commercial interior 3D visualization, the safest choices are CC0 and CC-BY. Below is a point-by-point breakdown so you know exactly what you're agreeing to when you drop a free model into a client project.

This is a common fear among designers and 3D artists: "I downloaded a free model, and now it turns out I couldn't use it commercially." Let's figure out when that fear is justified and when it isn't.

Why the License Isn't a Minor Detail

A 3D model, texture, or HDRI is a copyrighted work. "It's online for free" and "I can use it in a paid project" are two different things. The license is the author's permission: what you can do with the file, whether you have to credit them, and whether commercial use is off-limits.

For an interior designer, "commercial use" covers almost every job you do: a render for a client, portfolio visualization (which sells your services), a presentation to a developer, an asset inside a paid project. So the license matters to you even if you're "just making pretty pictures."

CC0 — Public Domain

CC0 (Creative Commons Zero) is the author waiving their rights to the fullest extent allowed by law. In effect, it's public domain.

What you can do:

Use it in commercial projects without restrictions.
Skip attribution (though thanking the author is good manners).
Modify, remix, and bake it into your own scenes and asset packs.
Use it with no watermarks and no signup.

What you can't do / keep in mind:

Don't claim you personally made the object if you didn't (but that's an ethics question, not a license one).
CC0 covers copyright, but not trademarks: a model carrying someone's brand logo is a separate matter.

CC0 is the gold standard for archviz. It's exactly the license Polyhaven (HDRIs, textures) and ambientCG (PBR materials) release their assets under. You grab them and never think about attribution.

CC-BY 4.0 — Free, but Credit the Author

CC-BY (Attribution) is also a free license: commercial use is allowed, modifications are allowed. The one mandatory condition is to credit the author (attribution).

What you can do:

Use it commercially.
Modify it and bake it into your projects.
Distribute the result.

What's required:

Credit the author's name and the source, usually with a link to the license. Where exactly depends on the medium: in a video's credits, in the project description, or in a "materials used" section.

Amazon Berkeley Objects — a large library of real-furniture models — is released under CC-BY 4.0, for example. It's a perfectly workable option for commercial work: just keep an attribution table in your project and add the author the moment you download, so you're not scrambling to collect links the night before delivery.

> Tip: keep a CREDITS.txt file or a line in the project description where you log the author of every CC-BY asset. That removes 90% of the attribution headache.

Royalty-Free — Where the Catches Hide

"Royalty-free" means "without royalties" — you pay (or don't) once and never owe the author for each subsequent use. But royalty-free ≠ free license. It's a marketing term, not a specific set of rights.

Under the "free" and "royalty-free" labels, almost anything can hide:

A ban on reselling or bundling into asset packs.
A ban on using the model "as is" (you can't sell it without substantial reworking).
Mandatory signup, download limits, credit systems.
Hidden attribution requirements or bans on certain project types.
Watermarks on the "free" version.

The takeaway: with royalty-free, always read the actual license text on the specific site. A "FREE" banner is not a license.

Side-by-Side Comparison

|---|---|---|---|

| Commercial use | Yes | Yes | Depends on the license |

| Modification / remix | Yes | Yes | Often yes, sometimes with conditions |

| Watermarks | No | No | Sometimes on the "free" version |

Common Mistakes That Force a Project Redo

"I downloaded it free, so I can use it commercially." Not always. Free for personal use and free for commercial use are different permissions.
Forgetting CC-BY attribution. Technically that's a license violation. The fix is one line — but you have to add it.
Confusing royalty-free with CC0. Royalty-free often bans resale and bundling into packs.
Not checking trademarks. A license for a 3D model doesn't grant rights to the brand whose logo is on it.
Downloading without saving the source. Six months later you won't remember where the model came from or what license it has. Save the license alongside the file.

How to Stop Keeping All This in Your Head

The simplest way to avoid mistakes is to grab assets where the license is shown on every file. The MorfVision catalog has 8,656 assets strictly under CC0 and CC-BY 4.0 (sources: Polyhaven, ambientCG, Amazon Berkeley Objects, and a set of vendor models):

Every asset clearly shows whether it's CC0 or CC-BY and who to credit for attribution.
Everything is free for commercial use — CC0 with no conditions, CC-BY with author credit.
No signup, no credits, no watermarks — exactly what's missing from "free" royalty-free libraries.

Bottom Line and Next Step

For commercial work, remember three rules: CC0 — grab it and don't think twice; CC-BY — grab it and log the author; royalty-free — read the full license before using it. If you want to remove the risk entirely, work only with CC0/CC-BY and keep the source next to the file.

Practical step: open the CC0/CC-BY asset catalog on morfvision.store — the license is visible on every file and no signup is required. Any model you like can be opened straight in the Vision-AI browser AI editor to build a scene without installing a 3D package.
