Change Material settings through script

Questions & Answers
1

Hello

I procdurally generate a tessellation material

p.renderer.material = new Material(Shader.Find("Tessellation/Bumped Specular (displacement)"));
p.renderer.material.mainTexture = heightMap;
p.renderer.material.SetTexture("_ParallaxMap",heightMap);
p.renderer.material.SetTexture("_BumpMap",heightMap);

And now I want to change the height and edge length of the tessellation shader/material.
How do I do that with a script? I cant find any function for that.

look here :Unity - Scripting API: Material

there are a set of get functions you can use. I’m assuming you length are height are float
so you will use the Material.GetFloat

so:

render.material.GetFloat("Height")
render.material.GetFloat("EdgeLength")

if your setting parameters you will use the Material.SetFloat
so it would be

render.material.SetFloat("Height", 0.1234f)
render.material.SetFloat("EdgeLength", 70000f)

you can do this for vector
hope it helps
