Eclipse Cannon final concept. I really love how the solar panel moustache turned out :)

Designed a lot of moving parts for the cannon arms to make the whole thing more dynamic when it transforms and takes the shot!

Eclipse Cannon mechanism - Super fun to design those solar panels to deploy and instantly give the whole design the signature Robotnik look :)

Eclipse Cannon transformation sequence. Very challenging design to get the 'cannon arms' to tuck into the underside. (Unfortunately the arm transformation not used in the film)

Landing Gear

Cupola & Access Hatch

Side Thrusters & Landing Gear

Early exploration sketches. This established the overall direction to take before 3D concept phase.

Blockout and exploring the mechanics of the cannon arms.

Defining the mechanism and details of the cannon arms.

Exploration of additional solar panels.

Early development and blocking. Visualizing how it makes the shot.

Early development and blocking. Spaceship mode with thrusters bringing it up to space.

Eclipse Cannon - interior design. Working out the space and how things fit inside.

Designing it like a nuclear fusion reactor. Shadow would race around the walls to power the cannon.

Reactor core that transfers the energy out to the cannon arms.

Cupola design. (different from final version in the film)

Charging up with Shadow's energy!

Challenging to design interior space with a circular layout; making sure all sorts of design variations sit and fits.

Finding interesting way for Shadow's energy to flow around the interior.
