I can’t get TrueSky to build out in my UE5 project. and compiling my project in visual Studios is blocked by TS unless it’s set to false in the engine defaults file. 
CompilerResultsLog: ERROR: Expecting to find a type to be declared in a module rules named ‘TrueSky’ in UE4Rules, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null. This type must derive from the ‘ModuleRules’ type defined by Unreal Build Tool.
