Change SpriteRenderers Texture2D in runtime

Questions & Answers

I created a character using unity 2d tools. I sliced a Texture2D to create the sprites.
Now I want him to change skins during runtime. So I have two Texture2D with differences in its clothes but the same UV coords.
I thought that changing the spriteRenderers material _MainTex would do it, but it keeps using the original Sprites.

SpriteRenderer[] renderers = GetComponentsInChildren<SpriteRenderer>();
if(use skin 1){
	skin = texture2D_1;
}else{
	skin = texture2D_2;
}
for (int i = 0; i < renderers.Length; i++) {
	renderers*.material.SetTexture("_MainTex",skin);*

}
I also tried renderers*.material.mainTexture = skin;*
And I tried with sharedMaterial.
I would like to change the Texture2d from where Sprites are taken, in runtime of course.
How can I do this?

Found the answer reading the Sprites/Default shader.
The _MainTex property has the [PerRendererData] attribute which means the texture is provided by the renderers MaterialPropertyBlock and not by the material.
So instead of setting the materials texture, I had to set a new property block to the renderer like this:

SpriteRenderer[] renderers = GetComponentsInChildren<SpriteRenderer>();
if(use skin 1){
    skin = texture2D_1;
}else{
    skin = texture2D_2;
}
for (int i = 0; i < renderers.Length; i++) {
    MaterialPropertyBlock block = new MaterialPropertyBlock();
    block.AddTexture("_MainTex",skin);
    renderers*.SetPropertyBlock(block);*

}
Now it works :smiley:
