The Hedgehog Engine has been used in several Sega games outside the Sonic the Hedgehog series:.

With the help of multiple in-house tools, it also allows the developers to edit the stages in Autodesk Maya and quickly see the results in-game. The goal of Hedgehog Engine 2 was to provide cutting-edge rendering visuals that seamlessly react to changes in gameplay and the environment in real time.

Color grading and consistent pseudo-bloom post processing effects.

Curvature-dependent reflectance function (CDRF) to render subsurface scattering of the characters' skin.

Capsule shadows to imitate ambient occlusion on the characters.

Image-based lighting (IBL) with parallax correction to provide natural looking reflections.

Spherical gaussian global illumination (SGGI), which prevents artifacts of conventional light mapping methods.

In it, Sonic Forces art director Yoshitaka Miura stated, 'We wanted to achieve not only realism, but also the atmosphere of the design culture that existed in 80s graphics in 3D.' The article highlights features such as: In 2018, Japanese computer graphics magazine CGWORLD published an article about the Hedgehog Engine 2. The engine was developed by Sonic Team to improve lighting and shadows and other problems that occurred with the original Hedgehog Engine. The main features of Hedgehog Engine 2 are improved global illumination, the addition of physically based rendering (PBR), and improved shadows. It was developed around the same time as Sonic Forces, with Sonic Forces being the first game to use it. The Hedgehog Engine 2 is the successor to the original Hedgehog Engine.

Sonic Unleashed ( Xbox 360/ PlayStation 3 version only).

Post-processed high-dynamic-range (HDR) bloom.

Light is reflected off of Sonic as well, to make sure that he didn't look 'out of place' as reviewers would claim from past Sonic games. The basic concept of the light field is that light bounces off every single object on screen, creating an ultra realistic look on the area. It also uses a piece of technology called the light field, which can generate CGI-quality graphics in the in-game graphics system. The Hedgehog Engine features seamless camera transitions between 3D and 2D perspectives. The engine was in development for three years, beginning in 2005. It is not compatible with PlayStation 2, Wii, or Nintendo 3DS hardware because they are not powerful enough to handle its next-gen lighting and visual effects. The Hedgehog Engine is a graphics engine, and has no bearing on gameplay.
