I am trying to set the color on a material via scripting, but is doesn’t work. This is the line that should do it:
renderer.material.SetColor("_Emission", Color.red);
The shader I am using is particle/vertex lit. Any ideas why this won’t work? It works on normal vertex lit.
Look in the shader and see what the property is called, if “_Emission” isn’t working.

This doesn’t exist unless you made it yourself. If you are actually using a builtin shader, please tell us which one it actually is. If you are using your own shader, please post it, and I’ll see if I can figure that out.
If you’re talking about “Particles/VertexLit Blended”, however, then you need this:
renderer.material.SetColor("_EmisColor", Color.red);
I am having the same problem…
pasted in the code from the unity scripting manual…
Tried every option for color name… but it always shows up white…
I debug logged the property, and the values are what I set it to.
I can click on the object while its running and change the material color just fine.
but using this script doesn’t create a material with the defined color… its always white, what is wrong with it please ?
string shaderText =
“Shader "Alpha Blended" {” +
“Properties { _Color ("Main Color", Color) = (160,170,10,80) }” +
“SubShader {” +
" Tags { "Queue" = "Transparent" }" +
" Pass {" +
//" Blend One One ZWrite Off ColorMask RGBA" + //Blend One One
" Blend SrcAlpha OneMinusSrcAlpha ZWrite Off ColorMask RGBA" +
" Material { Diffuse [_Color] Ambient [_Color] }" +
" Lighting On" +
" SetTexture [_Dummy] { combine primary double, primary }" +
" }" +
“}” +
“}”;
myMaterial = new Material(shaderText);
//none of these work, not the color above… its always white ?
//myMaterial .SetColor(“Main Color”, new Color(160, 170, 10, 80)); !!!
//myMaterial .SetColor(“_Color”, new Color(160, 170, 10, 80));
//myMaterial .SetColor(“color”, new Color(160, 170, 10, 80));
//myMaterial .SetColor(“_Emission”, new Color(160, 170, 10, 80));
//myMaterial .color = new Color(160, 170, 10, 80);
I can’t read that. Did you try making an actual shader file, a material to go along with it, and testing that?
no, I coped it from the unity scripting docs.
I don’t want to make a shader file, as I want this to be dynamic material created, without having to drag and drop it onto a object/slot.
if I make a shader… can I still find it and add it to dynamically created primitives at run time ?
That about with different colors ?
thx for reply
Of course you can. Just use the second method instead of the first.

I actually don’t know why you’d create one with text, though I believe I’ve seen Eric do that, so maybe he can enlighten us. I hate looking at that text-in-code garbage, personally.
thanks…
interesting… I got method 2 working… but with the same result… its always white…
It correctly sets the correct shader., the object shows up, the script is running, not errored out.
I just cant figure out how to set the color ?
any ideas ?
GameObject cyl = GameObject.CreatePrimitive(PrimitiveType.Cylinder);
Shader shadr = Shader.Find(“Transparent/Diffuse”);
cyl.renderer.material = new Material(shadr);
cyl.renderer.material.color = new Color(160, 170, 10, 80);
cyl.renderer.material.SetColor(“_Color”, new Color(160, 170, 10, 80));
cyl.renderer.material.SetColor(“MainColor”, new Color(160, 170, 10, 80));
cyl.renderer.material.SetColor(“Main Color”, new Color(160, 170, 10, 80));
maybe I cant set the color on an object right after its been instantiated/created… ? do I have to wait until after its own Awake() or Start() function is called ?
or maybe it needs a texture set ?
Two things.
1. Use the Code button in your posts.
hah hah, doh !
thanks
well might I suggest that Unity fixed their color picker to show 0 to 1, instead of 0 to 255 then in next unity version 
thanks muchly
