Textureの値渡し

var tmpTexture = CopyTexture((Texture2D)texture);
tmpTexture.Apply();

コピーロジック

public Texture2D CopyTexture(Texture2D source)
{
    var texture = new Texture2D(source.width, source.height, TextureFormat.RGBA32, false);
    var renderTexture = new RenderTexture(texture.width, texture.height, 32);
    Graphics.Blit(source, renderTexture);
    RenderTexture.active = renderTexture;
    texture.ReadPixels(new Rect(0, 0, renderTexture.width, renderTexture.height), 0, 0);
    RenderTexture.active = null;
    RenderTexture.DestroyImmediate(renderTexture);
    return texture;
}
