This simple tool allows you to generate and shape dew drops on the surface of an object. As it uses instances, you can scatter a huge amount of drops without reaching your memory limit.
To use that you need to append the Dew Generator.blend to your scene, selecting the Dew Generator node inside the NodeTree, add a geometry node modifier to the object and select the Dew Generator.
