The Default Cube Render challenge in Blender was an exciting and creative challenge for Blender users. It involved creating a unique and creative render from a simple default cube scence that was provided as a Blender file. The challenge encouraged the user to think outside the box and come up with creative ways to use the cube to make a unique render. FYI in Blender it is customary to delete the default cube when starting a new project. I guess thats why they created the contest. Poor Cube. Not sure where my render would have ranked as I did this project 6 months after the contest was over.
