Here’s how to participate: just use the daily prompt to create a model using any method you choose (modeling, sculpting, scanning, etc.). Then upload your model to Sketchfab and tag it with the challenge tag (#3December2020) and the topic tag (shared daily on the Forum).

If you complete the 21 entries and submit them in a collection by January 4, you will be entered into the challenge prize draw.
