3D Challenge: Sports & Hobbies

Do's & Don'ts

To help you better understand the technical requirements of the challenge and the feedback you may receive, we have illustrated each of the rules with examples of what would and wouldn't qualify for the competition.

1. Only 3ds Max and Maya formats are accepted (.max, .3ds, ma, .ma).

At this point in time, Adobe Stock is only accepting 3D models created in this software. Since the models are going to be sold on both CGTrader and Adobe Stock, users are not allowed to create models with the student version of the software. By default, student versions limit commercialization options.

2. Materials assigned to geometry must be Chaosgroup V-Ray Standard Material (VRayMtl).
Texture maps should be in PNG format. Texture image(s) should be square resolutions (minimum of 2K, 2048 x 2048).

3. Models should be single-subject only. No groups or series of objects are eligible.

This requirement can sometimes get a bit tricky, but as a general rule of thumb - don't be afraid to submit a single object even though it looks too simple to you. We understand that it would make sense to have a water splash in a glass but for this challenge, please strive for a single object and only relevant to the theme (e.g. don’t submit the glass, but the water splash is really we are after).

4. The scene should consist of the 3D model and connected V-Ray Standard materials only.

No lighting setups should be present. Hidden and unused nodes should be deleted from the scene.

5. UV Layout: 0-1 space.

6. UV Layout: non-overlapping.

7. Rotate the asset so the most interesting side faces toward the Z Positive axis in Maya or Y Positive Axis in 3ds Max.

8. Freeze Transformations (Reset xForm in Max).

9. Place the model to sit on top of the origin (0, 0, 0). Floating models are not accepted.

10. Model should not have any missing faces or open holes.

11. No subdivided surfaces.

12. Poles should have a maximum of 5 edges.

13. Flatten all modifiers ("delete history") before submitting the model to the challenge.

14. Normals for the entire model should have consistent facing direction.

15. Only quads are accepted (no automatic tri-to-quad conversion). Triangles can be used sparingly and only where absolutely necessary.

16. Model should be in real world scale (in centimeters).

17. Model should not display any logos or trademarks.

18. Preview image render (no text in the images).

19. Model should only be under a royalty free license in order to qualify.

20. Use English only in naming the files with, camelCase or underscores in titles. No spaces or special characters should be used.

1. CoffeeCup - Good, TazaDeCafé - BAD
2. “CoffeeCup.max” - GOOD, “Coffee_Cup.max” - GOOD, “Coffee cup.max” - BAD
3. “CoffeeCupV01.max” - GOOD, “coffee_cup_v01.max”- GOOD, “CoffeeCup(01).max” - BAD, “CoffeeCup-V/1.max” - BAD

For the best model:

1st place winner:

• Meeting all technical requirements
• Quality of the model in regards to functionality, versatility and appearance
• Detail, innovation, and general achievement in design of the model
• Clear and attractive presentation on CGTrader.com and from the perspective of Adobe Don’t forget to include quality model images, write detailed descriptions and apply relevant tags

All the criteria mentioned above apply to portfolio prizes as well. A designer is considered eligible for the portfolio prize when more than two 3D models are submitted for the challenge, meet all the criteria, and are approved by the CGTrader team.

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.

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 21st 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.
