Hello everyone it is me again with my eternal shader issues!
This time I am trying to blend the texture of my character with the color of the material in front of him to add a somewhat x-ray effect.
Here is my current scene Imgur: The magic of the Internet . At first look the character may look darker but it is just the lighting affecting the Main camera. The main color of my character is white and if he stands behind a red square (just like in my scene), I want his main color to change accordingly.
So far I think I have coded something that should at least give me some change of texture but nothings happen. Even changing color directly in my inspector doesn’t alter my texture. Anyone can help me on that? Here is my code:
Shader "Outlined/Bumped Diffuse" {
Properties {
_Color ("Main Color", Color) = (.5,.5,.5,0)
_OutlineColor ("Outline Color", Color) = (0,0,0,1)
_Outline ("Outline width", Range (0.0, 0.03)) = .005
_MainTex ("Base (RGB) Trans. (Alpha)", 2D) = "white" { }
_BumpMap ("Bumpmap", 2D) = "bump" {}
}
