How can we reproduce this? (What steps trigger the problem? What parameters are you using for processing? Include screenshots. If you are having issues processing a dataset, you must include a copy of your dataset uploaded on Dropbox, Google Drive or https://dronedb.app)

Use the generated 3dtiles file to load it in cesium 1.99, causing the browser to crash. The raw data used are: https://github.com/merkato/odm_wietrznia
Does ODM provide the function of dividing obj files into small files by grid? Whether it will support splitting obj into multiple small obj files in the future, converting each small obj file into 3dtiles, and finally summarizing to generate tilesets.json With this obj file splitting, you can load a large amount of data and significantly reduce the memory consumption of the browser.
