Lightact works with various USB cameras and video capture cards. They both use the same interface in the Devices window, which has been tested with various types of USB cameras and Datapath video capture cards. To read a texture from a video capture source the first step is to insert a Video capture card in the Devices window. You do that by right-clicking, hovering above Video capture and clicking on Add new.

A Video capture node will appear.

In its Properties on the right, you have to select one of the available sources. On this list there should be all the inputs on your video capture card and all connected USB cameras. Once you select one of the possible sources, type in the resolution. Please note, that the selected Source device has to support this resolution. After that, you check the Streaming checkbox and if everything is set up correctly, you should see a green Receiving label below the checkbox.

Getting the texture in Layer Layouts

To receive a texture from this Source device in Layer Layouts you open one of the layers and insert a Video capture reader node.

You select it and in the Parent device section make sure the correct Video capture node is selected.

Lightact should now be able to read from that video capture source as shown below. Please don’t forget that in order for the layer to be alive the transport has to be on the layer (the connections should blink).
