Game documentation

This is where you can find information on how each game utilizes assets, shaders, sca parameters and more.

Textures

Describes various types of textures utilized by each engine.

Split up into Hedgehog Engine 1 and Hedgehog Engine 2.

Shaders

Lists of shaders for each game that are specified for each material and determine how the material gets rendered ingame.

There are several shader principles that are shared between games:

• Physically based rendering (PBR)

• Normal mapping

• Weather

• Vertex colors

• Mesh layers

• Deferred rendering

• Dithering

Shaders are documented for all games that are natively supported by HEIO:

• Sonic Unleashed

• Sonic Generations

• Sonic Lost World

• Sonic Forces

• Sonic Origins

• Sonic Frontiers

• Shadow Generations

Additionally, earlier titles may make use of shader features.
