XR Venue Lab is a Windows application, built on Unreal Engine 5, that rebuilds the LED screens of a venue in 3D and plays your live video on them in real time.
You import the Advanced Output XML from Resolume, and every slice appears as a screen in a 3D room at its real size. Your content arrives live through NDI® or Spout, so you can walk around the venue as the technician would, check how each screen looks from the floor, and fix the mapping before the show — not during it.
- VJs and visual artists who want to see how their content works on a specific stage.
- Visual designers and production companies who need to show a client what a show will look like.
- Technicians who prepare a venue mapping in advance and want to check sizes, positions and pitch.
- Resolume XML import: screens, slices and output resolution are read straight from Resolume.
- Live video on the screens through NDI® or Spout, up to four input channels.
- 3D editor inside the program: move and rotate screens with a gizmo, type exact positions, join screens edge to edge with the magnet, make groups, enable or disable slices, undo and redo.
- Real size by LED pitch, chosen per Screen, so each screen measures what the real one measures.
- Technician view: walk or fly through the venue at eye level (1.65 m).
- Save and open venues to reuse them or share them with colleagues.
- Graphics quality levels (LOW / MEDIUM / HIGH) for different computers.
- Built-in update check: the program tells you when there is a new version.

XR Venue Lab es un programa para Windows, hecho con Unreal Engine 5, que reconstruye en 3D las pantallas LED de un venue y les pone tu video en vivo en tiempo real.
Importás el XML de Advanced Output de Resolume y cada slice aparece como una pantalla en un recinto 3D, a su tamaño real.

- Importa el XML de Resolume: pantallas, slices y resolución de salida salen directo de Resolume.
- Video en vivo en las pantallas por NDI® o Spout, hasta cuatro canales de entrada.
- Editor 3D dentro del programa: mover y rotar pantallas con un gizmo, escribir posiciones exactas, unir pantallas borde con borde con el imán, armar grupos, habilitar o deshabilitar slices, deshacer y rehacer.
- Tamaño real según el pitch del LED, elegible por Screen.
- Vista del técnico: caminar o volar por el venue a la altura de los ojos (1,65 m).
