Is there a way to access an entity's current material from code?

[havenphillip]

If I drag a material onto a model or brush, how can I then reference that material from a code placed on that object or brush without having to create a material then add a bunch of textures? I just want to reference the material I put on it. Something like a Material:GetCurrent() for the entity?

Actually I see GetSurface() but I'm getting this funky looking rock which ought to look more like the second picture.

Here's my code here so far:

function Script:Start()

    --mat = Material:Load("Gloss/wet_rock.mat")
    mat = Material:Create()
    surface = self.entity:GetSurface(0)
    surface:SetMaterial(material)
    shader = Shader:Load("Gloss/wet_rock.shader");
    mat:SetShader(shader)
    self.entity:SetMaterial(mat)
    shader:SetFloat("puddlesize", self.puddleSize)
    shader:SetFloat("puddlefade", self.puddleFade)
    shader:SetFloat("intensity" , self.intensity)
    mat:Release()

end

Ah ok I see. But now it's blue, even though the color is set to 1,1,1. How do I fix that?:

    surface = self.entity:GetSurface(0)
    mat = surface:GetMaterial()
    mat:SetColor(1,1,1)
    shader = Shader:Load("Gloss/wet_rock.shader");
    mat:SetShader(shader)
    self.entity:SetMaterial(mat)
    shader:SetFloat("puddlesize", self.puddleSize)
    shader:SetFloat("puddlefade", self.puddleFade)
    shader:SetFloat("intensity" , self.intensity)
    mat:Release()

Ah it's my shader. I got it. Thanks for reading lol
