Niiice I’m glad there’s someone like you interested in off-grid building and I hope there’s many others in this Forum. Maybe is there a thread for it ? This would help implement new “obj”, textures and material in SH3D, just a thought.

As for your point on thermal issue, you need to know that I’m a Canadian (Québec) and face the same in my home country. There’s a large citizen movment toward off-grid endeavors and they are experimenting some very serious solutions. If you wish, I can send you some links. I know also a lot of people involved in the same field in Germany and France and producing some very convincing results. But I guess you know all that.
