Revitalization of a part of railroad network in Adelaide, Australia.
-Lumion Pro 3.2.1
-GTX 670 2GB
-Sketchup with many plugins
-3ds max for export to DAE when Sketchup decides to die
-Adobe After Effects - used for intro and text during animations, slight color correction done as well.
- about 16 hours to render at 1080p, 12.5 seconds per frame
All models done in Sketchup
Took almost a week for 4 people to make all the box models of houses and stations.
Lumion side of things was done in 1 day (18 hours) plus few hours of fixing after prelim animation was done.
Biggest problem was the size of Sketchup files that kept crashing when exporting to DAE so we split up terrain into 3 models plus separate roads from buildings giving us 5 DAE models:
Far away city........... 12mb
Google maps base..... 55mb
3d terrain hills.......... 213mb
Road network........... 158mb
Frustrating part was that Sketchup autosave would take 4 minutes to save, every 20 minutes. Frequent crashes made it impossible to disable autosave feature since it was saving our asses every couple of hours.
Whenever models were updated in Lumion it would take 4-6 minutes to update.
Project size was a huge problem - 5.7km x 4.6km
469 Outdoor Library objects
As the screenshot shows final project had 29.7 million 3D points and it was running at 3fps when view was stationary, dropping to 1 fps when trying to navigate. This dropped to 10 fps when in 1 star editor mode.http://postimg.org/image/atstycrf7/full/
Due to 2gb GPU, Lumion was having crazy graphical glitches (black lines appearing randomly), and it NEVER crashed, not even once. Unable to reduce the amount of any objects I had to turn to the dreaded "Limit all textures to 512x512" in Lumion settings. Removed all glitches but made the hi-res base terrain model look like crap, to be honest. Hours of work collecting hi-res Google snapshots were wasted
All in all, we made it in the end but the quality had suffered as a result of limited graphics memory and unrealistic "time vs scope of works" timeline.
Learned a lot about the limits of the program and a lot about its stability.
Could not have done it without Lumion.
