Blender house

This is a journal so I feel that I must include what is taking many hours of my time at the moment! Ro and I are doing a course to learn to use Blender 3D. This is a house I rendered with lighting and rather opaque windows. They were so see-through that it was impossible to tell that there was glass in there, so I pushed the roughness up - a bit too far!

The overall stripy effect is taking a photo of a computer screen. Not sure how you remedy that one!
