I'm a lousy architect so I really don't do "appartments". In my projects I attempt to make illustrations that tells a story.
I make most of the models and textures myself, and my projects usually ends up weighing around 1.5 – 2 GB.
All of these images are rendered on a Mac Pro 2015 12 core 24 threads,
and were done prior to the introduction of EnkoNyito's new light sources.
Here are some interiors:
These images are all created in SH3D during the last three years, and presented as rendered,
with no retouching or other adjustments – just downscaled from 3440px to 1280px and converted to jpg,
to save space on my server.
Of course everything looks sharper and more detailed on the originals,
so I have included an original sized rendering (4.5 MB) HERE
Hope these are more in accordance with your specifications.
