This small scene contains all the meshes and textures from the Intergrade version of the game.
This model includes:
Optional outside view collection (only the outside of the house and sector 6 walls.
An HDRI of the sector, optional eevee only lamps.
This model works for both eevee and cycles, for cycles just hide the eevee lamps since there's a bunch of emission meshes used for this model and since eevee can't use emission meshes for illumination I added those extra lamps to give that effect. You don't need to use them for cycles since it creates unescesary extra calculations.
