标题: 混合顶点色和贴图的shader
代码:

Shader " Vertex Color 2" {

Properties {

_Color ("Main Color", Color) = (1,1,1,1)

_MainTex ("Base (RGB)", 2D) = "white" {}

}
SubShader {

BindChannels {

Bind "Vertex", vertex

Bind "texcoord", texcoord

Bind "Color", color

}

Pass {

Tags {"LightMode" = "Vertex"}

Color [_PPLAmbient]

SetTexture [_MainTex] {constantColor [_Color] combine texture * primary, texture * constant }

}
}

FallBack "Diffuse", 1

}有时候需要在上面显示阴影,就需要换一种方法了

复制内容到剪贴板代码:

Shader "Diffuse Vectex Color" {

Properties {

  _Color ("Main Color", Color) = (1,1,1,1)

  _MainTex ("Base (RGB)", 2D) = "white" {}

}
//Category {

// Blend AppSrcAdd AppDstAdd

// Fog { Color [_AddFog] }

SubShader {

  // Pixel lights

  Pass {

Name "

PL"

Tags { "LightMode" = "

ixel" }
