LightAct features a unique integration with Unreal Engine. It can be described in the following main points:
First, both apps run on the same machine, which reduces system complexity and latency.
Second, LightAct controls the pace of Unreal's render cycle, which prevents the 2 apps for fighting for the computer resources.
Third, LightAct passes runtime data such as Timecode to Unreal, so that the content is in perfect sync.
And fourth: LightAct uses unique sub-frame latency technology, which can reduce the added latency to below 1 frame (usually it's just a few milliseconds).
So let's discuss the overall workflow in a general way before diving into the specifics in the following chapters.
Unreal Engine 5 Compatibility: Texture Share plugin is broken in Unreal Engine 5, so this workflow isn't possible. Epic Games is working on a patch to fix the plugin and it should be available shortly.
LightAct Unreal Engine Plugin
LightAct's Unreal Engine plugin is a required component for making the integration work. It takes care that the data is passed back and forth between the two apps.
