Submitting an Exercise to be Graded
How to Submit an Exercise to CG Cookie
Submitting an exercise is one of the best ways to grow your Blender skills and get direct feedback from CG Cookie’s instructor assistants. Depending on which exercises are available, you’ll see different submission options.
Note: Exercise submissions require an active CG Cookie membership.
Step One – Click Submit Your Work
Make sure you’re logged in. When an exercise is available, you’ll see a Submit Your Work button at the top left of the exercise page—just above the video player or image.
Step Two – Fill Out Your Exercise Submission
Depending on the course, you’ll be submitting one of five exercise types:
- Image Exercise – Upload a render of your work (usually a .jpg or .png).
- File Exercise – Upload a .zip, .pdf, or .blend file for review.
- Text Exercise – Submit written content, such as notes, reflections, or code snippets.
- Video Exercise – Share a link to your video hosted on YouTube, Vimeo, or Wistia.
- Sketchfab Exercise – Connect your Sketchfab account and link a published 3D model.
Once you’ve chosen the type, add a title and description for your submission. This helps reviewers understand your approach and intent.
Image Exercises
Image exercises are the most common and the fastest to submit. To make sure your render displays properly:
- Recommended size: 1280×720px (you can upload larger images, but display cropping may occur).
- Accepted formats: .jpg or .png
- Maximum file size: 5 MB
File Exercises
File exercises are great when you want instructors to inspect your .blend file or other supporting materials.
- Add a title and description.
- Upload your file(s). Multiple uploads are supported, and large files may take extra time to process.
Text Exercises
Text submissions are useful for assignments involving writing, scripting, or theory-based reflection. You can type or paste your work directly into the built-in text editor before submitting.
Video Exercises
In this type of exercise, you’ll supply a link to any public video hosted on YouTube, Vimeo, or Wistia.
Sketchfab Exercises
A free Sketchfab account is required to participate in these exercises. Uploading your 3D work allows instructors and fellow artists to view your wireframe, shading, and topology directly in an interactive viewer.
By default, models uploaded to Sketchfab are set to Draft Mode, which keeps them private. When you’re ready to share your model as an exercise submission, click the Publish Model button in Sketchfab.
To create a Sketchfab exercise submission:
- Click the Submit Exercise button on the exercise page under the video.
- Fill out the form and type in your Sketchfab Username in the username field.
- Click Search to list your published models.
- Select the model you want to submit, then click Add Submission.
If your model isn’t showing up, make sure it’s published (not in Draft Mode) on your Sketchfab account.
After You Submit
Once your exercise is submitted, it’s reviewed by CG Cookie’s instructor assistant team. You’ll receive a pass/fail grade along with personalized feedback, specific notes on what you did well and what could be improved. You can resubmit your work as many times as you like.
While you wait for feedback, take some time to vote and offer critiques on other artists’ submissions. Offering constructive feedback is a valuable skill for any artist and helps strengthen the CG Cookie community.
When your review is complete, you’ll get a notification and can view comments directly on your submission page. Keep an eye out for that feedback, it’s one of the most powerful ways to improve your Blender skills.
