LightAct 4.2.0 is available

We are thrilled to announce the release of LightAct 4.2.0. It is more robust, flexible and packed with exciting new features. Here are just a few of the many improvements you’ll find:

Unreal Engine 5 integration

LightAct is now fully integrated with Unreal Engine 5.1.1, one of the most advanced game engines available today. This integration offers a powerful set of tools to create immersive and interactive experiences.

Multiple Timelines

You can now create multiple timelines in LightAct, each of which can be populated with multiple sequences. This new feature allows you to play several timelines at the same time, fade between them and much more. It gives you the tools to create truly unique and engaging experiences.

Sequence master fade and master volume

Every sequence can now be customized with its own fade in, fade out, master fade and master volume. Combined with fade controls on individual layers, this offers even more flexibility in designing your show.

Tracking Visualizer

Tracking Visualizer is a brand new feature which helps you visualize the tracking information inside your Viewport. Every individual beacon is now represented in the viewport so that you can easily check if everything is set up in the correct way.

ASIO & Multi-channel audio support

LightAct now fully supports multi-channel audio. It’s now possible to route your audio to any audio channel available on your sound card.


LightAct can now lock to the incoming video signal thus fully supporting high-end broadcast environments.

LUT node

Light Act’s LUT node allows you to change the colors of any other texture based on the mapping defined by the lookup table. This can be useful for a variety of purposes, such as color grading, color correction, or creating stylized looks. LightAct supports both .cube and .3d files.

Luma key node

The Luma key node is a powerful tool which can be useful for removing a solid background or other specific areas from a texture based on their brightness values. Together with other keying nodes, such as the chroma key, it achieves extremely precise keying results.

Other improvements

In this new LightAct version, you can also expect better Asset management, improved Timeline and Sequence management nodes, smoother polygon mask management, a new Delay node and more.
