Sketchfab 3D Sculpting Challenge: Underwater Creatures

Back to overview

Hello Sculptors, it’s time for another round of our new 3D sculpting challenge! Like last time, you’ll get two weeks to work on a topic that encourages everyone to collaborate – we’ll combine the final entries into one large scene afterwards, linking each entry to the original.

This month, the topic is ‘Underwater Creatures’ – realistic or fantastical fish or other critters. So brush up your biological sculpting skills, grab some reference pics and start creating!

Our sponsor Shapeways is providing a 3D print of the winning model.

Read on for the full rules, but the TL;DR version is: sculpt any ‘underwater creature’ model, upload to Sketchfab and set ‘Downloadable’, tag with #3DSculptUnderwater to enter.

Update: the winners are in!


We’ve been trying to think up new ways to make these challenges interesting to both new and experienced 3D sculpting artists and also more community oriented – how can we work together to build something and give back to the wider 3D neighbourhood, so here’s how we’re running this challenge:

  • You can use any 3D sculpting tool that you like. If you’re new to sculpting, take a look at free tools like Sculptris, Blender or our own Sculptfab.
  • Once you’ve created your 3D model, upload it to Sketchfab, tag it #3DSculptUnderwater and set it to Downloadable.
  • Share what you’re planning to create on the challenge thread in the forum – for extra fun you can collaborate with other participants and create pieces that work well together!
  • Models must be set to Downloadable to take part in the challenge – partly so we can combine the top entries in our final tabletop war scene but also because we are encouraging you to create a legacy of free and open 3D content that can be used by artists, game devs and hobbyists.
  • Submit new work only.
  • Submission deadline is Monday, March 20 (23:59 New York time – EST).



Shapeways is offering $100 in 3D printing credits to the winner – enough to get your design 3D printed in a great material and ship to you! We’re adding 3 months of Sketchfab PRO to the prize pot.
