What if one million humans lived on Mars? This is the question HP asks of artists and designers in a new - and ambitious - contest: MARS HOME PLANET. Can the community design a utopian urban society, on Mars, for one million humans?

The contest takes place in three steps. Steps one and two - concept and 3D modeling - are complete, with amazing results. Now the community is being called into action for step three: it’s time to render!

Participants may use the files submitted by other users in the challenge, and build on them to create the final render. Anyone can join! Help the designers of life on Mars, and imagine what the future of humans will look like on the red planet.

Want to simulate an uber-realistic Martian environment, respectful of the laws of physics? We’re giving away 7 free materials on Substance Source to help you on the way! You can find them easily with the “MarsHomePlanet” tag in the Substance Source search bar.
