Voxel art is becoming quite popular lately, and at Sketchfab we have launched a cool Fantasy-themed contest about it. You can use freely (gratis) available tools to design your work like Qubicle, MagicaVoxel and 3D-Slash, and them import and perfect (bake light etc) your scene in Blender. Or, if you like, you can just stack your blocks in Blender ;-)
In a world built on three dimensional pixels, a hero must design and build a fantasy voxel world and protect it from an unknown evil that may determine the fate of an entire kingdom. Export your tale to Sketchfab using annotations to tell your story and by the power of Greyskull… you might be victorious!
Prizes include a Lego Studio box, 3D prints of your work, licenses of Qubicle, a Parrot Airborne Cargo drone and Sketchfab subscriptions and goodies.
