// Simplified Bumped Specular shader. Differences from regular Bumped Specular one:
|
|
// - no Main Color nor Specular Color
|
|
// - specular lighting directions are approximated per vertex
|
|
// - writes zero to alpha channel
|
|
// - Normalmap uses Tiling/Offset of the Base texture
|
|
// - no Deferred Lighting support
|
|
// - no Lightmap support
|
|
// - fully supports only 1 directional light. Other lights can affect it, but it will be per-vertex/SH.
