Selecting your Engine

Unreal Engine 4

The trueSKY Unreal Engine 4 plugin comes as either a branch of the UE4 engine on GitHub, or as a separate installer for the binary distribution of UE4. For further instructions, head to our Unreal page.


To use the trueSKY Unity plugin, you need to install the appropriate Unity package to your Unity project. For further instructions, please head to our Unity page.


The trueSKY SDK can be integrated with a game/simulation in two different ways. Firstly, it is possible to dynamically link with the trueSkyPluginRender library and API just as we do for Unity and Unreal. The second option is to link the trueSKY libraries directly, and access the lower-level classes directly.

To learn more about our SDK, head over to our page here.

Standalone Sky Sequencer

We also have our Sky sequencer as an executable, which can be used to create sequences that can be imported into trueSKY in any engine.

If you have already installed trueSKY, you should head over to our tutorials page to learn how to use trueSKY to its full potential.
