#### 介绍

UE4动态加载模型支持FBX/OBJ等等，使用assimp库。UI使用蓝图开发，功能使用C++开发
目前实现功能： 
1. 动态加载模型
2. 射线选取，高亮
3. 碰撞检测
4. 动态生成菜单
5. 自定义插件
6. 右键弹出菜单

#### 效果图
- 打开本地文件

- 高亮，射线选取

#### 使用说明


1. 工程使用UE4.21.1版本
2. 如果第一步build失败，请将..\ThirdParty\assimp\bin\x64目录下的assimp-vc140-mt.dll拷贝到..\Binaries\Win64目录下即可
3. 打开scene.bhp\scene.json文件，bhp是自定义的文件格式，里面定义了场景的相关描述信息，json格式，导入的模型需要放在..\Scenes\Mesh目录下
4. 在scene.bhp\scene.json中添加对应的模型信息，运行程序选择场景文件，程序就会加载导入的模型了

#### .bhp文件说明

#### 后续计划
空闲时会不定期添加功能，主要看时间或者大家有什么希望添加的功能也可以提出来
