an issue with the environment map when loading multiple identical models

[XiaoHu1994]

What happened?

After upgrading from 1.123.1 to 1.124.0, when loading multiple identical models, black areas occasionally appear in the environment map from a certain perspective. I speculate that this may be related to changes in the DynamicEnvironmentMapManager.js file or asynchronous loading.
