Shader Graph Gradient

Questions & Answers
1

I have a shader graph that has a gradient property and it wasn’t too long until I figured out that you can’t set gradient properties in code. So I looked for a way to take a list of colors from the user and convert it to
a gradient texture, and that worked well. But I need to set the texture to the shader graph as well, so I need a way to convert the texture to a gradient so that I can sample it. Thank you!

Hello @Captain-Ravioli !
Why you’re doing the double work?
If you need to set the colors of the gradient, don’t convert them to a texture… Use them directly setting the gradient’s colors in this way:

colorKey = new GradientColorKey[2];
colorKey[0].color = Color.red;
colorKey[0].time = 0.0f;
colorKey[1].color = Color.blue;
colorKey[1].time = 1.0f;

// Populate the alpha  keys at relative time 0 and 1  (0 and 100%)
alphaKey = new GradientAlphaKey[2];
alphaKey[0].alpha = 1.0f;
alphaKey[0].time = 0.0f;
alphaKey[1].alpha = 0.0f;
alphaKey[1].time = 1.0f;

gradient.SetKeys(colorKey, alphaKey);

Obviously, use this pattern, but you need a for loop to set all colors in the right time.
