PBR Challenge: Interior Design
In celebration of the amazing design work done on the Designer Schwag and Sports & Hobbies challenges, we are happy to announce yet another round of creativity, collaboration and amazing prizes - all coming your way with PBR Challenge: Interior Design. The good news is that this time the technical requirements are less restrictive and are focused on making a perfect PBR model.
For this challenge, we are looking for realistic single object models related to interior design. This includes, but is not limited to, household objects, furnishings and decorations. From a dining room table to a bookshelf; an armchair, sofa or chair to a chandelier or lamp; from cushions, curtains, or vases to architectural elements such as decorative doorknobs or ornate picture frames - think outside the box and show us what 3D can do.
Please pay attention to the fact that we are looking for single object models, and therefore, no scenes or interior sets will be approved.
These models are intended to work well with Adobe Dimension CC, an app that makes it easy for graphic designers to create high-quality, photorealistic 3D images and composite 2D and 3D assets to build products shots, scene visualizations and abstract art. To be eligible and prepare your models in the right way, it is important to review all of the technical and legal 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...and thus single object per single file
- OBJ geometry file with BaseColor, Metallic, and Roughness with optional Normal, AO and Opacity maps.
- Only quads are accepted. Triangles can be used sparingly and only where absolutely necessary.
- Poles should have amaximum of 5 edges.
- Single UV set per mesh (0-1 space, non-overlapping).
- 200k polygons (triangles at render) is a good limit to try to cap poly count.
- 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.
This challenge is a great opportunity to not only win an amazing prize but to build a model that is perfectly constructed for the design community. By joining this challenge you also have the opportunity to become a contributor to the Adobe Stock 3D marketplace (and earn sales from there). This could be with no additional work on your part since CGTrader will take care of the work for you!
Don’t forget to also review 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, so if you are submitting a chair, lamp, sofa or other interior design model - make sure that these designs are unique and not copied from real-world objects. 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.
Also, we advise you to scan this blog post for additional legal information.
Use this opportunity to win cash prizes, subscriptions to different Adobe apps and to become part of the future of 3D content at Adobe. Join now!
Below are the top quality models that were participating in this challenge.
Awards & Prizes
For this challenge, we will select six winners in two different categories - one for the best model and one for the best portfolio. These will be judged by the Adobe and CGTrader teams based on how well the asset(s) conform to the technical and legal specifications along with the quality of the model in regards to functionality, versatility and appearance.The three best designs will be awarded the following prizes:
For the best model:
1st place winner:
- $1,500 USD
- A complimentary year subscription to Creative Cloud by Adobe
2nd place winner:
- $1,000 USD
- A complimentary year subscription to Creative Cloud by Adobe
3rd place winner:
- $500 USD
- A complimentary year subscription to Photoshop by Adobe
In the portfolio category, three winners will be selected using the same criteria above, but instead of looking at a single model, we will be reviewing all of the models submitted by each artist.
The best portfolio winners will be awarded:
1st place: $1,500 USD
2nd place: $1,000 USD
3rd place: $500 USD

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.
This is PBR challenge, where I can learn more about PBR?
PBR, or Physically Based rendering, is fast becoming a standard in 3D world, so it is worth learning the techniques and workflows. If you want to learn more, we advice to take a look at the following resources:
- Vol.1: The theory of physically based rendering
- Vol.2: Practical guidelines for PBR texturing
- Feeding a physically based shading model
- Physically Based Specular for Artists
- Physically Based Rendering Encyclopedia
How do I know my model is eligible for the challenge?
First, when uploading your 3D design, click on the Interior Challenge checkbox to mark your model as an entry. This will inform the CGTrader team that the new submission was received. Since the CGTrader team reviews every model submitted for the challenge, you might get several emails from our team on the status of your model (check your inbox for emails from firstname.lastname@example.org). Once the 3D model goes through the approval process, you will receive email stating that your model has been approved. This congratulations means that your model is eligible and is now competing for the prizes. You will then be able to also see your model in the Entries section of the challenge.
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, which means you cannot submit models with an Editorial License or Custom License for the challenge. Please read the terms and conditions to see what entering the challenge entails and so that you understand the expectations around removing the asset. This includes not deleting eligible assets from
