I have modelled a house for a technical information piece and I was trying to test a render just to see if everything was ok, but the walls of the house did not show in the render window. I was using the archipack addon to make walls and windows but something is amiss. I have materials selected and added to the walls, just a simple diffuse shader. This render is from Eevee, but I had the same result when I was rendering in Cycles.
Would love to hear from you experts what I can do to make this better. Best regards Ulf
