I wanted to call it in the rules I created. ctrl+shift+G after the rules I created will keep the results consistent when I used fileRandom.</P> Mon, 17 Feb 2025 01:56:25 GMT biaozeng 2025-02-17T01:56:25Z https://community.esri.com/t5/arcgis-cityengine-questions/the-global-random-seed-is-invoked-at-cga/m-p/1585926#M11508 <P>I found the seedian function in the old question and found that positive values are the same as the global random seed, but negative values are different.
