Sketchfab Blockbench Challenge: Alien Moon Landing

Back to overview

This week’s challenge is out of this world…. We’ve teamed up with Blockbench, a free and open-source low-poly modeling software that offers direct upload of your creations to Sketchfab, to challenge you to create an alien moon landing scene.

Imagine what an alien moon landing would look like and then bring that vision to life with Blockbench, upload your model to Sketchfab, and tag it #BlockbenchAlienChallenge to enter. New to Blockbench? The makers recommend these tutorial videos and are available to answer questions here.
