Setting up trueSKY on UnrealEngine 4

Setting up trueSKY on Unreal Engine 4

trueSKY  for Unreal Engine 4 is supplied as a fork of the UE4 source code, including some trueSKY binaries, to be found at In these instructions we’ll use [UE4] to denote your Unreal Engine 4 source code directory; this is the directory that contains UE4.sln and GenerateProjectFiles.bat.

Enter your GitHub username in your Simul profile here, this needs to be the same username you have connected to your Unreal Engine account, here.

Clone the UE4 source code on your PC, following the instructions in the ReadMe file to extract the dependency zip files.

The installer puts the plugin into the “[UE4]\Engine\Plugins\TrueSkyPlugin” directory in your UE4 installation. The trueSKY binaries are in “[UE4]\Engine\Binaries\ThirdParty\Simul”.

There are two trueSKY modules in the UE4 project – TrueSkyPlugin, and TrueSkyEditorPlugin.

You can obtain a licence here:
