I"ve spent the last 5 or so years struggling with Archicads 3D window (non rendered) image quality and finally came across something that now makes a huge difference.
Very simple. When publishing / exporting out any 3D image, you must ensure you do this from your primary high-resolution device screen, NOT a secondary low res plug-in screen. For whatever reason, Archicad exports these images accordingly to the quality of your screen itself?? I didn't realise this and haven't had much luck getting technicians to provide this useful info.
We work on macs, and have secondary screens that are usually very poor quality. Each time I export with Archicad opened in this screen, my images are degraded vs doing so from my mac screen. See the export screen information attached - same publishing settings and images done from different screens.
Most people suggest to undock the 3D window screen from main window and maximise to full extents. This helps only in a small way. Had this issue since Archicad 20 or so.
Thanks for posting this. I have also struggled with this and have never been overly happy with the resolution I could get out. I will definitely try this next time.
