         | using Blender/AutoCAD already know what material/style they
         | want.

         | There's bigger problems than just materials, the renders invent
         | whole architectural features that don't exist in the source
         | material. Windows and doors appear out of nothing, ambiguous
         | features are guessed arbitrarily, and some features that do
         | exist in the source are ignored and smoothed over.
         | 
         | It's the usual story with AI image generation where it's easy
         | to get something vaguely presentable with a loose set of vibes,
         | but the more specific you want the details to be the more of an
         | uphill struggle it becomes to get what you want. And in this
         | case the user probably already has a 3D model they can feed
         | into a conventional renderer with the exact parameters they
         | want.
         | 
         | Another issue is that the user will probably want to produce
         | multiple renders of the same building, but with AI it's
         | extremely difficult to get consistent results. Again, not an
         | issue with conventional approaches to rendering.

       | Can we get this as an autocad addon?

       | TIL from off-gridders and homesteaders about passive solar design
       | so that the air moves through the home without HVAC (compared
       | with high rise buildings where it is necessary to pump water up
       | like a gravitational potential water tower.)
       | 
       | Does ReRender AI have features for _sustainable_ architecture?
       | 
       | Prompt: "Design a passive solar high-rise building with maximal

       | Either merge into blender or take up some RTX rendering chops

       | I'm just trying to design a home right now actually. Played with
       | sketchup to assist, but I'm prly going to try and so sketches and
       | use ai to render for me if that's viable.
       | 
       | But being able to get realistic renders from just floor plans is
       | the holy grail. Please let me know if this is viable at all with
       | rerednerai
       | 
       | Looks great tho, congrats

         | I'd recommend Sweethome3D to trace the floorplan and then you
         | can export it as a .obj to a program like Twinmotion to do
         | visualisation and lighting with pathtracing etc.

           | That's a really awesome recommendation, thank you! I'll give
