Version 9.4
For UE 5.5, 5.6, and 5.7
Expanded the features for water level on UDS/UDW to support water bodies of various heights like lakes and rivers. Will work by default with Water plugin water bodies, and is built to be usable with any water surface actor classes that have any static mesh component for the water surface. See the info on setting this up in the Water Level documentation entry.
Added logic to the Actor Weather Status component to monitor if the actor goes under the water level and affect material state accordingly. The new options for this are in the Settings category on the component.
Added support for using the DLWE snow/dust trails on custom landscape layers beyond the dynamic snow/dust coverage, for things like mud or sand. The DLWE documentation entry has info on how to set this up.
Created 27 video guides demonstrating how to use features on UDS and UDW, linked in the relevant documentation entries.
Added functions to UDS called “Get Time of Day as String” and “Set Time of Day With String” to allow controlling and sampling time using formatted strings (12:34 PM, 15:45:12, 00:30, etc)
Added a variable, Time of Day String, to Basic Controls on UDS. This is for both seeing and setting the Time of Day using a formatted string.
