    Hello all ! First of all, huge thanks to Oliver for this wonderful software, it is amazing to see a sandbox in action! I work with a municipal engineering department, and we have just built our very own sandbox to use for community outreach / education and well because it is awesome. The build / install went VERY smoothly however I can’t seem to figure out how to enable the rain function ? Perhaps it was mentioned somewhere but I may have missed it. Any help is greatly appreciated !

    I will attach photos tomorrow when I am back with the sandbox as the only pictures I have are it not in final state, thanks!

    Water simulation / rain is turned on by default, but you might have to configure the elevation range at which the software detects “rain clouds,” especially if you use a non-standard base plane elevation.

    To test the water simulation, create a water tool: When the sandbox software is running, press and hold the “1” key, move the mouse to highlight “Manage Water Locally” from the tool selection menu, and release “1” to select. Then press and release “2” to assign the secondary function. Afterwards, press and hold “1” to let it rain underneath the mouse cursor.

    (You can use any keys or buttons you want instead of “1” and “2”.)

    To make it rain from your hands, you need to move your hands into the rain elevation range and hold still. By default, the rain range starts a few centimeters above the highest terrain elevation configured in your color map. You can configure the rain elevation range directly via the -rer <min elevation> <max elevation> command line parameter, where <min elevation> and <max elevation> are elevations relative to the base plane configured in BoxLayout.txt, in centimeters.
