I find that it is hard to steer the to a good result. Once you have something you like, but the rest is not there yet, there is no mechanism to keep parts of it. The next try can be totally different. For example, at some point the solar panels were right, but that changed again later. There is no way to keep the correct solar panel. I wish I could draw a circle around it and keep that.
I tried to highlight (blue) certain elements in Archicad, so I could give those elements a specific finish. But that has no effect.
Gardens and people are though in Archicad, but I could not add anything to it. Also I would like to replace a sphere with something else. That also does not work.
The Prompt strength did not give any better results for me.
