从SU模型中打开D5渲染器时显示对模型的关联消失了，需要手动跟保存的D5文件关联，并且关联过后会出现材质丢失，已经对丢失材质赋予材质时无法赋予得情况，我想对该问题请求帮助和技术支持谢谢。
我的D5版本：Version 2.10.1.1002
我的SU版本：2023版
Hi @1169614660
I apologize for the inconvenience this issue has caused. Are you perhaps using a cloud storage to store these files? If so, please try to download them locally then proceed to work on them in that manner. The workflow with cloud storage has yet to be optimized. Thank you for your understanding.
