Light and Camera LOPs now have a “Guide Scale” parameter which controls the size of the guide geometry for these primitives in the viewport. The default value for these parameters sets the value to the inverse of the meters per unit value of the stage, producing a consistent real-world size for these primitives. The camera LOP also has a parameter that can hide the camera from the viewport camera menu (in cases where the camera is for utility purposes, not meant for looking through).https://www.sidefx.com/changelog/?journal=&categories=&body=&version=18.5&build_0=417&build_1=417&show_versions=on&show_compatibility=on&items_per_page= [www.sidefx.com]
