Question

使用产品：https://github.com/SuperMap/s3m-spec

操作系统：win10 x64

数据类型：.obj(S3M_SDK\SampleData\cyt_model)

问题详情描述：下载贵公司S3M_SDK源码，编译样例代码，运行样例3代码：

设置Altizure数据作为源路径，设置s3mb缓路径，将Altizure以Ro的方式写入到s3mb中。

执行到：UGFileParseModel* pFileParser = (UGFileParseModel*)UGFileParseManager::CreateFileParser(nFileType);

报错，pFileParser =null
