Texture Sharing
There are 3 workflows to get Unreal Engine's texture (also called content) back to LightAct:

Thrower2UCam

In this workflow, LightAct thrower is used to create an nDisplay viewport.
This is the most common workflow.

Projector2UCam

In this workflow, a LightAct Projector is used to create an nDisplay viewport.
This workflow is very similar to Thrower2UCam, however, it is recommended to use it only on very specific use cases.

ViewportUCam

This is the only workflow where you are not launching nDisplay from LightAct, because it relies on a specific Unreal Blueprint to share Unreal's Viewport.
