Hidden Alley: A Community Project

Work with us to create a library of free and open 3D assets!


Amidst the urban hustle, concealed by concrete, a gap in the shadows opens to reveal a forgotten and overlooked charm.

The Hidden Alley is a community project whereby our community has helped us to create amazing high quality assets.
An environment was then formed around those assets to highlight the fantastic work that everyone has done.
We want to thank everyone who took part as well as the Prize Providers for making this project a success.

Hidden Alley: A Community Project

Our previous community project, The Shed, was a major success! Special thanks to all the fantastic artists who took part and helped stock the Shed full of amazing high quality props.


Check out the final Shed scene here

So then, lets do another one!

Introducing: The Hidden Alley

We want to work together as a community once again and this time to create an Alleyway environment, filled with high quality props created by dozens of different artists (like you!)

We want you to make props that would fit the alleyway theme. We’ll create an environment for these props to go in, and share all the assets openly on polyhaven.com, along with the final scene itself.

Though we have over $2000 worth of prizes to reward to the best artists, this project is at it’s core about building a library of free content for everyone.

Theme

What is the Hidden Alley?
Tucked between towering buildings, hiding in plain sight, lies a dark and narrow alleyway. It’s easily missed by the hurried crowds and noisy traffic that rushes on by. The ground is littered with discarded items and debris. However, despite its unkempt appearance, it has a certain charm that attracts those brave enough to explore its depths.

Whatever might fit a scene like this, we’ll find a place for it.

Reference

Create as many assets as you like, however only your top 3 will be eligible for prizes. Just remember that quality matters more than quantity.

There are a few requirements to assets we can accept:

  • They have to be your own original creation.
  • They have to be able to be published as CC0 (more on this further down).
  • They have to be consistent with the standards and quality of the models currently on the site.

Prizes!

A Very Special thanks to all the prize providers helping us give back to you.

That’s 39 prizes with a total value of $2,760!

The project will conclude on the 22nd of May. After that, the artists whose assets are accepted will vote alongside our patrons for the top creations and winners will get to choose from the pool of available prizes.

The artist in first place will get first pick from the prize pool; after that, second place will then pick from the remaining prizes; third place will pick after that; then fourth… until there are no prizes left.

As a participation prize, all artists whose props were accepted (including those who didn’t win any prizes) will be given our Poly Haven Asset Browser Add-On for Blender, or alternatively access to Poly Haven’s Nextcloud server which contains all our assets, as well as a special role on our Discord server.

How to enter

We have a public Trello board where you can share the progress of your asset, ask for feedback and Submit your asset (more on this further down). This is meant to serve as the central hub of the project where we can track the progress of each others work and help each other with feedback and constructive criticism.

  1. Read the rules and requirements below.
  2. Pick an idea for a prop that would fit in an Alleyway environment.
  3. Create this prop in a photorealistic style.
  4. Don’t use any resources that would mean your prop could not be published as CC0 (more info below).
  5. Make sure your creation is fit to be used by other people (e.g. good UVs, topology, baked texture maps, etc).
  6. Share your work in progress on the Trello Board and gather feedback from other artists to make your work better.
  7. When you’re done, Move your card over to the “Submit your asset” list and follow the provided checklist.
  8. Fill in the Submission Form.

Work together

There is no reason to work in isolation. We have a special section on our Discord where during the course of the project we’ll be hanging out in a voice chat while working on our own assets and the scene.

We highly recommend sharing your progress on forums or other Discord communities. This way you can get feedback from outside of our little community too, and help spread the word about the project.

Don’t know what to make?

Don’t worry! We have created a list of ideas which can be found on the Trello board.

Having too many of the same kind of prop may not be as useful as having lots of different things, but don’t let that discourage you from making whatever it is you feel like making 🙂

Here’s a simple prop workflow that you can check out as an example of the kind of thing we’re looking for.

Rules

It is of utmost importance that your assets can legally be published as CC0. This means submissions that include any copyrighted content of any kind will be rejected. See more in the FAQ below.

  • All entries must be original works.
  • In order to help us verify your work we will need you to provide a list of all the sources or information regarding any resources you had used that you did not make yourself. This includes which texture resources you used on your 3D model.
  • We encourage you to favor quality over quantity, though there is no limit to how many assets you can submit. Each prop should be a separate submission.
  • Any software can be used as long as the work that is produced allows it to be released as CC0.
  • 3D scanned assets will be allowed as long as the asset does not include any copyrighted or trademarked material and meets the requirements below.

Asset requirements 

Ultimately Poly Haven is striving for quality over quantity so we have to be quite specific about the technical requirements and level of quality that we publish.

  • Assets should be photorealistic, suitable for next-gen game engines and visual effects. Please get feedback and critique from other artists before submitting your work.
  • Assets should be in real-world scale, with rotation and scale applied.
  • Fully UV unwrapped and textured with standard PBR maps. Minimum 4k resolution textures.
  • Any procedural shaders should be baked down to a simple set of PBR Maps/images so as to be compatible with any 3D software.
  • If you have used Substance to texture your asset, you are encouraged to include the Substance file in the submission as this helps us with processing the asset.
  • Use only custom original textures painted specifically for your asset, or textures that are already CC0/public domain compatible. There is a list of resources like this on the Trello board.
    • This means content from popular sites like textures.com or Poliigon cannot be used.
    • Working with built-in tools and procedural textures (e.g. in Substance) is fine, as long as they are baked to the UVs of your model and not shared on their own.
    • If in doubt, read the terms of use or license agreement of the resource you’re using, or ask on our Discord.
    • You will be required to share a list of links to the resources you used so we can validate this.
  • 3D scanned assets should be reasonably retoplogized and include a full set of PBR maps (diffuse/albedo, roughness, AO, normal, displacement and metalness if applicable).
  • Assets must be provided in “.blend” format. If Blender is not your software of choice, check some tutorials on how to import your asset into Blender and make sure it looks the way you want it.

If you’d like to make our lives easier, take a look at our Technical Standards document for more details on what we we’ll need before we publish it on polyhaven.com.

FAQ

Can I submit multiple assets?

Please do! Create as many assets as you like, however only your top 3 will be eligible for prizes. This is to ensure that quality is favored over quantity.

If you submit multiple assets that are very similar (e.g. Small geometry tweaks or minor texture changes ) we might consider them as a single asset.

Can I use images from Pixabay/Unsplash?

These two websites do not actually use the CC0 license, but their licenses are similar enough to CC0 that for most images (except for those depicting a recognizable person or trademark) you may incorporate them in your assets. Just read their license terms carefully to ensure you’re abiding by them, and then in our submission form provide a link to the image(s) you used so that we can verify your source and credit the author (which is not technically required, but is nice to do and builds trust with our users).

For other similar sites, make sure their license is similarly lenient – if you’re not sure just ask in the comments below or on Discord and we’ll check it out.

Note that textures from popular sites like textures.com and Poliigon are not compatible with the CC0 license and cannot be used. For any other sites, read their licenses very carefully.

Can I use public domain resources in my assets?

Yes. Although CC0 is not exactly the same as public domain and it’s not possible to apply the CC0 license to existing public domain content outright (re-licensing it), it is possible to use that content as part of a greater design and release that new work (a derivative) under a new license. Just make sure the image in question is actually in the public domain, and not simply “free”.

You will still need to provide a list of sources for any included public domain works.

What happens if I use copyrighted resources as part of my asset?

If you tell us about it, then we will unfortunately have to reject your submission. If you don’t tell us, that would be plagiarism. If you don’t include any sources, we assume that your asset is completely your own original work, and will publish it as CC0 on Poly Haven. Despite us publishing your creation, you are the one licensing your creation as CC0 and remain legally responsible for it. If it’s later discovered that your design is plagiarized, we will immediately remove it and provide your contact information to the party raising the dispute.

    1. Hey Levi!
      Currently we don’t support decals on the site however if the decals were significant enough and could be supplied under our model selection we might allow it.
