Self-Illuminated Shader Family
The Self-Illuminated shaders will emit light only onto themselves based on an attached alpha channel. They do not require any Lights to shine on them to emit this light. Any vertex lights or pixel lights will simply add more light on top of the self-illumination.
This is mostly used for light emitting objects. For example, parts of the wall texture could be self-illuminated to simulate lights or displays. It can also be useful to light power-up objects that should always have consistent lighting throughout the game, regardless of the lights shining on it.
Self-Illuminated Vertex-Lit
Assets needed:
- One Base texture, no alpha channel required
- One Illumination texture with alpha channel for Illumination Map
Self-Illuminated Diffuse
Assets needed:
- One Base texture, no alpha channel required
- One Illumination texture with alpha channel for Illumination Map
Self-Illuminated Specular
Assets needed:
- One Base texture with alpha channel for Specular Map
- One Illumination texture with alpha channel for Illumination Map
Self-Illuminated Bumped
Assets needed:
- One Base texture, no alpha channel required
- One Normal map normal map with alpha channel for Illumination
Self-Illuminated Bumped Specular
Assets needed:
- One Base texture with alpha channel for Specular Map
- One Normal map normal map with alpha channel for Illumination Map
Self-Illuminated Parallax
Assets needed:
- One Base texture, no alpha channel required
- One Normal map normal map with alpha channel for Illumination Map & Parallax Depth combined
Note: One consideration of this shader is that the Bumpmap texture’s alpha channel doubles as a Illumination and the Parallax Depth.
Self-Illuminated Parallax Specular
Assets needed:
- One Base texture with alpha channel for Specular Map
- One Normal map normal map with alpha channel for Illumination Map & Parallax Depth combined
Note: One consideration of this shader is that the Bumpmap texture’s alpha channel doubles as a Illumination and the Parallax Depth.
