近期玩虚幻4玩到了AR这块，网上查询了好多资料少之又少，所以做了一些总结，我用的虚幻版本是4.25。
虚幻4AR需要插件——Google ARCore（安卓的是Google ARCore，苹果的是ARKit，本人穷到喝西北风，身边只有安卓手机，所以iOS系统没细究，嘿嘿）
打包安卓环境。
编辑—项目设置—Android
安卓环境美配置前是红色的条条，如果没记错靠右有一个按钮，点击一下就好了。
往下翻，这个也是。
这两个打上勾。
点击安卓SDK
前三个分别是sdk，ndk和jdk的路径。最后两个不要动。文件我放百度网盘链接了

回到虚幻主界面，文件—新建关卡。
拍一张图片，用于后续在这张识别的图片上生成AR三维模型。
图片导入项目，保存当前关卡。
项目设置—地图和模式—Default Maps—编辑器开始地图和游戏默认地图设置成刚保存的地图。
新建blueprint文件夹,在文件夹里右击—蓝图类—玩家控制器，重复以上步骤新建Pawn，Actor，游戏模式基础。
双击Pawn，给Pawn加个摄像机。
左上角有个添加组件—摄像机组件
双击游戏模式基础，把玩家控制器类和默认Pawn类改成blueprint文件夹中新建的
项目设置—地图和模式—默认游戏模式改成blueprint文件夹下新建的游戏模式基础。
新建一个文件夹data，右键“其他”内加入数据资产，添加ARCandidateImage和ARSessionConfig。
做一个手机识别框，并导入项目，双击打开，压缩设置更改为用户界面2D,纹理组选择UI
之前上传的识别图片做同样的操作步骤。
新建一个控件蓝图（右击用户界面—控件蓝图）
在层级中放一个图像控件，并在图像中上传手机识别框这张图。
打开识别图片的数据资产，匹配识别图片，高度和宽度可以自定义，友好命名不能为空！不能为空！不能为空！否则后面打包失败。
打开另一个数据资产， 新增并匹配识别图像的数据资源。
打开之前保存的关卡，在世界场景中拖入定向光和天空光
开始编写蓝图程序（蓝图—打开关卡蓝图）
将控件蓝图添加到视口
事件tick后依次加入获取所有AR追踪图像、循环节点、获取检测图像。
新建变量，变量类型为“AR候选图像”，选择为第四个“映射”，与之前的空actor匹配。
全部蓝图如下
