What can I do to avoid such a phenomenon when I load 3Dtiles, a lot of computer memory, and a headline - like error.
I’m not sure what you mean by a headline-like error. Do you have a stack trace or image of the error?
To use less memory, you can set the tileset maximumScreenSpaceError. Setting it to a higher value should load the higher level of detail less frequently.
The following is an error shot：
Added: I’m using the uncompressed cesium.js code for version 1.41, memory from 4.6G to 13.4G, followed by the above error 。
Try the following settings:
maximumScreenSpaceError : 32,
skipLevelOfDetail : true,
immediatelyLoadDesiredLevelOfDetail : true
And leave the others at their defaults.
