Newbie to Blender In blender 2.91.0 I am making simple buildings and covering with texture using uv-mapping. Many of the faces are internal and will never be seen and have no texture applied to them. (The textures with the red letters in the attached picture)
Is there some way to select and delete the unwanted faces from the UV map? and hopefully rearrange the UV map using Smart UV project function or something similar to use all remaining space.[Image of my layout]
Apologies if this has been covered elsewhere
