TL;DR: Stop fighting Midjourney for architecture. It creates art, not buildings. In my experience over the years, you need tools that respect control nets or depth maps if you want to keep your sanity. I feel your pain man. Midjourney is great for mood boards but honestly its just a glorified hallucination engine. It doesnt know what a wall section or a setback is. If you have a firm deadline Thursday, you really need to pivot to something that takes your actual geometry into account. IIRC, there are some workflow plugins that let you layer AI over your SketchUp or Rhino files. It keeps the scale honest instead of letting the AI guess the floor heights. Someone told me recently that using a tool with a strict control-net implementation is the only way to keep your massing from looking like a melted blob. Not sure but I think looking into real-time rendering plugins for your modeling software is way better than trying to prompt your way out of this. Personally, I stopped trying to force pure generative tools to do CAD work ages ago. It just never ends well. Focus on getting your base geometry right in your software and then use a specialized AI pass for the textures or lighting. Good luck with the presentation, hopefully you can salvage the model by then.
