You can change Lumion materials (textures, reflectivity settings etc) for any individual surface in Lumion.
Each individual surface is defined by the material name or ID that you apply in the modelling application.
On import, Lumion then combines all faces that have the same material name in to a single combined surface. This makes it easy and rapid to update across faces by just selecting the surface anywhere in the model.
You will see that in Lumion, if you move the mouse over one of the faces that it will have a name - the material name applied in the modelling application. If the wall was applied with one material only to all faces, then all faces in Lumion have the same surface and material name.
So, if you have two walls, then you will need to go back to the modelling application and apply a different material to one of the walls, and then export/import using Reload (see your other topic) to update the Lumion Imported Model.
The same for a single wall, or for any faces of the wall, but where you want to have faces that have different materials.
Does that answer your questions fully?
