Workflow Process - Interior Image Alignment

Well, for a massive interior, RC really can struggle with UV’s and I also am trying to keep texturing efficient so I dont have 50 different textures. 

Using both a low poly texture for walls and simple objects are the key to a nice finish for a VR product, my problem is how to handle UV’s in 3rd party programs then using them back in RC.

Also I have no idea what baking a mesh means from a high to low poly, Is that for the mesh it self or just the texture? ugh so much to learn, I just need a good course to take which will get me up to speed quickly.
