Thanks for all help. Here's the same scene with your glass, soft shadows and some objects as well. Much better, thank you. The white stripes are gone too, don't ask me where to. It seems your glass was simply more realistic. It is also more reflective, which of course means the interior is more obscured. I don't understand how to control the transparency - in the Shaders inspector, there's only a color field under that label?
I want the 'plastic' looking walls - they match the softness of the antialiased picture, which shows a limewhite-painted house. And the image really transcends the slightly cold quality of our Nordic light in late summer mornings. Some Photoshop has been applied to the grass as well.
But 3D tree objects make my hardware choke. Is there some way to make the 2D billboard plants to throw more 'accurate' shadows? (I mean the 2D shadow casting mask would have to face the sun at the same time the 2D picture faces the camera - I have a slight recollection I've heard that's possible to do? Maybe not in Artlantis?)
Billboard vegetation is mostly much more realistic anyway.
I used "normal" glass (the procedural Art4.5 kind) for the balcony, but your glass is in all the windows. Also, the horizontal sun shade thingy above the windows at the right is presumed to contain some kind of less transparent glass, and that works quite well.
I'd also like to know how ArtR actually handles reflections. It seems that it assumes that the background picture in fact is cylindrical. It streches it all around the perimeter and calculates the reflections from that assumption. Could be slightly problematic, I think.
And PS:
I really do like this software - it's clearly worth both money and effort, despite my comments on Abvent. but some manual that goes into a little more detail on how to handle the advanced shaders and "expert" materials is really needed. I think a book from Dwight is a good idea, although if I were him, I'd try to find out about Abvent's plans before taking on such a task.
I will post this in the Artlantis forum as well. But I thought the Archicad users who read my late postings should see how the story ended, and also how useful this software can be with a moderate effort.
