The prompt implies that the computer's capacity is limited and cannot load an unlimited number of high-quality models. It will appear when too many blocks are loaded. Consider the following measures:

1. It is recommended to use DJI Terra's block splitting function, and customise the edge lengths up 300 × 300 m.

2. Unload some of the loaded high-quality model blocks before loading new ones.

3. Save the current operation, exit the software and reopen it. Then try loading new blocks.
