3D Challenge: Sports & Hobbies

3D Challenge: Sports & Hobbies

A couple of weeks ago, we launched 3D Challenge: Designer Schwag - a challenge balanced for the technical artist and creative designer in all of us. An easy and fun challenge, we asked our community (and still do - the deadline is open until August 27th) to model objects that 2D designers could use in their everyday work. What we didn’t mention, though, was that the Designer Schwag challenge was just the beginning. We have been preparing something more just for you!

We are excited to announce our new 3D challenge: Sports & Hobbies. We are using the same technical rules as Designer Schwag but exploring a new space for artists to explore and test their creative side.

For this challenge, we are looking for realistic 3D models of objects typically used for sports, hobbies, games and similar leisure activities. Musical instruments, paintbrushes and other art supplies, generic sports equipment, board games figures - these are just a few examples of what you could create for this unique challenge. Think outside the box and show us how stunning 3D can be!

As with our Designer Schwag challenge, these models are intended to work well with Project Felix, the new beta app from Adobe, and for use in the Adobe Stock 3D collection. To be eligible and prepare your models in the right way, it is important to review all of the technical requirements. Here are the key ones to consider (for a complete list, please refer to the terms and conditions section).

  • All submissions should be single-subject model
  • Only Maya (.mb or .ma) and 3ds Max (.3ds or .max) formats are accepted
  • Use VRay Standard Material (VRayMtl)
  • Only quads are accepted. Triangles can be used sparingly and only where absolutely necessary.
  • Poles should have maximum of 5 edges.
  • Single UV set per mesh (0-1 space, non-overlaping)
  • Real world scale objects (centimeters)
  • Asset names should use camelCase or underscores (no spaces), and be consistent respective to all dependent files. Use English only.

Don’t forget to also use the Legal Guidelines for Adobe Stock Contributors. These are similar to those that you already use for commercially cleared models on CGTrader. In short - we cannot accept any models showing trademarks or containing other non-proprietary content. Learn more about all of these topics - the theme, the technical and legal guidelines, and the associated Adobe Stock Contributors terms - in the dedicated section.

This challenge is an amazing opportunity to win great cash prizes, subscriptions to different Creative Cloud apps by Adobe and become a contributor to the Adobe Stock Collection.

Ends in: 22 days (2017-09-13 23:59:59 UTC)

Frequently Asked Questions

Please go through these questions before contacting us

Do I need to upload files or only images of my 3D design?

You need to upload files and images of your 3D design in order to participate in the challenge.

How do I know my model is eligible for the challenge?

While uploading your 3D Design, click on the Adobe Challenge checkbox to mark your model as an entry. Please make sure the model is submitted in the format required and provide the PBR texture details in the model description. At this time the object modeled should be a real-life object so sci-fi models will not qualify. Our team will review every model submitted so you will also be separately notified if the model is eligible or if there are specific issues to be resolved.

I don't want to put my entry model for sale. Do you have any suggestions?

Does earning money from your digital files sounds like a bad idea? For the CGTrader marketplace, try to put a higher price on it, let's say 300 USD. For Adobe Stock, the pricing tiers vary and might change over time, but your model would not be priced lower than $19.99 on Adobe Stock. You will be notified about the price of your model once it is set on stock.adobe.com.

I don't want to lose the copyright on my model after it is sold.

With both CGTrader and Adobe Stock, you continue to retain the copyright to your model.

For licensing on the CGTrader site, there are Royalty Free, Editorial and Custom licenses for you to choose from. Individuals or companies that buy Editorial licensed models can't use these for commercial purposes. If you would like to earn your share of a commercialized end product - you can add some specific terms on the model usage on the CGTrader site.

By entering this challenge you also accept that the model will be sold on Adobe Stock for commercial use so, please read the terms and conditions to see what this entails and so that you understand the expectations around removing the asset. This includes not deleting eligible assets from CGTrader or Adobe Stock for 6 months after the challenge end date.

How can I participate in the challenge?

Design a great looking photorealistic 3D model meeting all of the technical requirements for the challenge and upload the asset to CGTrader.

What if I put the required tag on my already published 3D model on CGTrader - do you treat it as a valid entry?

No. Only 3D models uploaded in the period from the 3rd of July 2017 to the 13th of September, 2017 will be treated as valid entries.

Do free 3D models participate in the challenge?

Yes, absolutely. Sharing artwork is always appreciated in the community although the model may be revenue generating if added to the Adobe Stock collection.

Do price tags play any importance when entries are being judged?

No. But do not forget that the prices are always judged by the customers.

I want to participate in the challenge so I am going to delete my already uploaded models and upload them again to meet the "publishing period" requirement. Can I do that?

No. We are tracking every deleted and uploaded model, so models that are deleted and re-uploaded will not be considered eligible.
