How to: Create shader and copy texture?
Hello,
My gameObject has a VertexLit Shader, but I want to switch to a Mobile Unlit Shader, with code. I tried this:
var MOBILEUNLIT : Shader = Shader.Find("Mobile/Unlit");
var TEXTUREIMAGE:Texture=renderer.material.mainTexture;
renderer.material.shader = MOBILEUNLIT;
renderer.material.mainTexture=TEXTUREIMAGE;
As you can see I am attempting to preserve the image in the Base (RGB) texture.
However, the object turns pink? What am I doing wrong?
Thank you kindly for any help.
EDIT: got it to work like this thanks to Professor Snake:
var TEXTUREIMAGE:Texture=SOME_GAME_OBJECT.renderer.material.mainTexture;
var MOBILEUNLIT:Material = new Material (Shader.Find("Mobile/Unlit (Supports Lightmap)"));
MOBILEUNLIT.mainTexture=TEXTUREIMAGE;
SOME_GAME_OBJECT.renderer.material=MOBILEUNLIT;
You can instead have two materials and copy the properties between them.
var vertexLitMaterial:Material=renderer.material;
var unlitMaterial:Material;
unlitMaterial.mainTexture=vertexLitMaterial.mainTexture;
renderer.material=unlitMaterial;
Thank you, but I was hoping to avoid having another object with another material.
Is there no way to create a shader and attach the texture like I posted?
You don't need to have another object. All you need to have is the material and reference it from the script.
Correct, however how do I do it without a material already created?
Can't I:
Create new shader with code
Assign image from other material to that shader
Apply new shader/texture to object
?
You can create the shader and then create a new material with that shader with the $$anonymous$$aterial(shader:Shader) constructor.
So basically:
var myShader:Shader;
var unlit$$anonymous$$aterial=new $$anonymous$$aterial(myShader);
Thank you, I got it working, and posted my code. I will upvote your answer once I get enough rep. $$anonymous$$uch respect!
Thank you Professor Snake, you pointed me into the right direction.
I got it to work like this:
var TEXTUREIMAGE:Texture=SOME_GAME_OBJECT.renderer.material.mainTexture;
var MOBILEUNLIT:Material = new Material (Shader.Find("Mobile/Unlit (Supports Lightmap)"));
MOBILEUNLIT.mainTexture=TEXTUREIMAGE;
SOME_GAME_OBJECT.renderer.material=MOBILEUNLIT;
I am using this to switch all materials to more Mobile friendly materials runtime, mainly because it seems IOS is really good at choking on everything.
