Real-time Design Challenge: Medieval Fantasy

Back to overview

Once upon a time in a land far, far away, there was a tiny kingdom hidden away in the mountains. And while its people were happy and led good lives, in the back of their minds there was always the worry about what might be at the other side of the mountains…

Update: the winners have been announced!

Welcome to our new community contest! We’ll be going back to medieval times to explore castles, medieval towns, knights, and perhaps… dragons? Anything is possible in this Medieval Fantasy!

This is a contest with a twist: we’ve teamed up with the amazing people of Mozilla, who are working hard on their A-Frame WebVR platform – a web framework for building interactive virtual reality experiences.

We’re combining the power of our two communities to create amazing WebVR scenes. In this contest, you, the Sketchfab community will create gorgeous real-time assets. The Mozilla A-Frame community can then use them in their projects and showcases.

Your task

Create a set of real-time assets in a medieval theme that can be combined with assets from other participants. You’re free to choose your focus, for example you could build modular assets for a castle environment, props to be used in your world, characters, weapons, animals etc. Display your own building assets in a final presentation piece.

Thanks to Mozilla, we’re able to offer the biggest prize pot you’ve seen on Sketchfab to date! You can win a VR-ready laptop (a real powerhouse: 32GB, GTX1070 card – you’ll love it!), VR headsets, a Wacom tablet and much more. The first 100 participants to open a ‘Work in Progress’ topic on our contest forum will also receive an exclusive Mozilla/Sketchfab Medieval Fantasy Cardboard viewer!

So we’re throwing down the gauntlet: do you have what it takes to create a Medieval Fantasy?

Visual style

As the goal of this contest is to create assets for the Mozilla A-Frame community, we want to make sure all building blocks will have the same visual style that ‘works together’. So we’ve put together a visual style guide that should to stick to. When in doubt ask us for guidance on the contest forum (see under ‘How to participate’).

Elements you should pay special attention to are the character and style of the assets and the color palette.

How to participate

To enter this contest, create a scene in the described visual style of Kevin Pauly’s work and theme. Build as many reusable components for it as you can. (For example: if you create a castle scene, provide blocks for walls, floors, doors etc.).

Start your own topic in the Medieval Fantasy contest forum to document your work in progress. When in doubt about the visual style etc, feel free to ask us for feedback on your entry. We’ll also be posting contest updates on this forum.

Publish the fully composed scene that leverages all your assets and tag it with #MedievalFantasyScene.

Publish each asset as a downloadable file (remember, the Mozilla people are going to pick and choose from our contest’s results for their own contest later this year). Make them available for download under a Creative Commons Attribution license (“CC-BY”), and tag with #MedievalFantasyAssets.

The submission deadline is Wednesday, November 1 (23:59 New York time – EST)

Example of publishing the individual assets

Why are we using the CC-BY license?
The Creative Commons Attribution licence (also known as CC-BY), ensures that artists are free to use and build upon your work. The only requirement is that they properly credit you, and that they indicate if any changes were made. The resulting work does NOT need to be released as Creative Commons. For in-depth information, please visit the Creative Commons website.

Technical requirements

We want to ensure that the assets of this contest can be combined into scenes that perform well for mobile WebVR. For this reason, you need to be mindful of the following requirements:

Performance considerations

  • For individual assets, aim for a 2k polygon budget and 512×512 texture maps (if you really need larger texture maps, be sure to always use ‘power of two’ sizes like 1024×1024 etc).
  • The total polygon budget for the assembled scene is 50k.
  • Try to keep the number of objects small as possible. You could merge static meshes and use a unique texture for all of them. For example if modelling a house, you will have a whole mesh and a texture for the structure itself and then independent meshes for movable objects like chairs, tables and so on.
  • Use static lighting and bake ambient occlusion and lightmaps if needed for your scene.

Other requirements

  • Use a PBR metalness workflow to set up your materials.
  • For scale, assume 1 unit = 1 meter in VR.
  • Sound and animation are optional. If you use sound, please include all .mp3 files in your original upload as it will not be in the GLTF download.
  • Make sure your assembled scene is easy to navigate using teleportation.

Terms and Conditions

  • No purchase necessary.
  • By entering this competition, entrants will be deemed to have accepted and agreed to the conditions.

    Wow cool ! Awesome ! Fantastic ! And I can”t found more powerfull words…

  • Juan says:

    Cool contest!! based on the prizes I was wondering if it was international and how would that work out.

  • ben lucas says:

    Great initiative, the prizes and the theme are good and I was really enjoying the idea of making a great cartoon city with “something” beneath the mountains !

    Btw, and I’m sorry for my honesty but it’s so sad that the visual style is mendatory and so dull. Sketchfab is such a great tool for presenting quality 3D works that it’s a shame to be obliged to do something so ugly with it!
    In addition, for me giving all my assets for free doesn’t help to sell this contest.

    Btw I like what your making guys, It’s only my own opinion. I will not participate for this one and I just wanted to share my thoughs about it with the community.

  • mimi says:

    i love this but dont get how to do it im new and i dont know how to do things on here email me if you can my email is mking9499@greenvilleschools.us

    • Bart Veldhuizen says:

      We’ll be happy to help you out with any specific questions you may have. Please post them on the contest forum!

  • KrossPhaire3D says:

    Awesome 😉

  • Douglas Rosa says:

    FOR THE PLUSHY!

  • Njordy says:

    As I understand the whole idea, the design/style should match. And the human figurines gotta be more or less identical in our models.

    Do we have to make em from scratch looking and the reference (they are simple, won’t take much), or there is a template file with a regular person to build on?

    • Bart Veldhuizen says:

      We still offer a fair degree of creative freedom, as long as the general ‘visual style’ matches the examples, you’ll be fine. There are no templates to work from.

  • Anthony Karanovich says:

    I want in on this sign me up!!! 😊😊😊

  • Keith Jones says:

    Hi
    Does geometry matter other than the polycount?

    • Bart Veldhuizen says:

      You mean topology? It probably goes hand in hand – if you have simple, clean topology it will perform well in a real-time environment.

      • Keith Jones says:

        Hi
        Yes I guess I do mean topology. I use Moi3d a lot and it outputs nice meshes for static models but lacks the edge loops needed for deformation. Is it OK to model in this way? It looks like it would fit with the type of style shown in the illustrations. If I make a few objects and post them here would someone be good enough to tell me if I should stop?

      • Bart Veldhuizen says:

        Sure thing Keith! Just start a WIP topic on the forum and mention @bartv or @seori any time you need help. This will summon us 😉

  • Paulo Pina says:

    Love sktechfab & moz:lla :3

  • Yash Jha says:

    Is this only for above 18 years of age. I am a kid of 13. Can I participate

    • Seori Sachs says:

      You can participate but if you’re a minor, you need to get approval from your parents before sharing your address with us.

  • Hi there! 🙂
    In the requirements section, by “static lighting” you mean that when I assemble my scene on sketchfab the light should be attached to the camera? Or do I have to bake it in the diffuse map? (e.g. bake all my lights outside sketchfab and upload all my models as “shadeless”?) Or can i use both this methods?

    • Bart Veldhuizen says:

      To be honest, I think this rule won’t be enforced. It’s best to submit model unlit so that they can be used in any kind of environment.

  • Art says:

    Hello, it seems I’m awfully late but nevertheless i’m still interested to attempt! If i may ask, is the theme only tied to the Medieval era of European region or are other regions allowed too?

  • Becks T says:

    Awesome.

    Would medieval feudal Japan fit into this brief?

    • Bart Veldhuizen says:

      Yes it would. Be advised though that the submission deadline is next week, so better hurry up 🙂
