### Shader code for blending textures using mesh.color

Source: https://docs.unity3d.com/Packages/com.unity.polybrush%401.2/manual/modes_texture.html

Use this shader code to blend four textures based on the mesh.color channel. The final color is computed by lerping between the base texture and three blend textures using the color components. This example assumes a shader with five textures: one base and four blend textures.

```hlsl
// sample the texture
fixed4 col1 = tex2D(_MainTex, i.uv);
fixed4 col2 = tex2D(_Texture1, i.uv);
fixed4 col3 = tex2D(_Texture2, i.uv);
fixed4 col4 = tex2D(_Texture3, i.uv);

fixed4 final_color = lerp(lerp(lerp(col1, col2, i.color.y), col3, i.color.z), col4, i.color.w);

```
