Here's another side-to-side comparison of ArchiCAD Corona Plugin test render (VFB interactive image, ~20-30 mins) at the top to the original 3ds Max Corona plugin version at the bottom - but this time of an exterior view.
I obviously spent a bit more time on the original image with some post-processing in Photoshop to make the colors pop a bit more and do a bit more sharpening, and I had also spent more time on it on the materials which look far superior, whereas in ArchiCAD I did minimal adjustments (like with the glass and metal) but not as much time.
.....this plugin has great potential.
The closest to a simple 'point-and-click' render engine I've ever worked with.
(Maxwell comes close, but the render times with that were absolute torture just to get a clean image.)
