Title: Project that almost destroyed me - Tonsley Rail Extension
Post by: milosv on October 15, 2013, 06:32:28 am
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
Buildings.................. 70mb
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
Lumion objects:
5119 Trees
926 Cars
453 People
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.

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.

Like it too. Very sexy the train-road-camera

You wrote "Unable to reduce the amount of any objects I had to turn to the dreaded "Limit all textures to 512x512" in Lumion settings."
My english is not so good. Would you be so kind to explain in other words the issue and the solution?!

Cheers TF

Sure thing ToFI,
Issue is due to size of textures I had and size of the model, Lumion was using up all graphics card memory and would start showing black lines and triangles all over the scene, randomly.
Sometimes certain objects would disappear completely.

Solution is to either reduce number of objects in the scene or to go into settings and click on the "limit to 512 texture size"  (first icon in settings)

what that does is reduce every texture you have to only 512x512 pixels. Object textures look average in quality but at least it renders.

Having 512x512 texture on an object which is small and far away from camera makes no difference, it still looks good. but for my google maps base texture it was rather catastrophic.

Project looks great and I think you are being too hard on yourself. Everything looks fantastic!!

Also, there are scripts that will pull large sections of satellite imagery and stitch them together for you. No need to manually stitch screenshots. You can find it here, but you might need some knowledge of python, or at least a friend who does  :-D

Nothing more frustrating than working feverishly to complete a large-scale project only to keep encountering limitations in both the software and your own system that impede your progress to completion.

From the video, I agree that in the end you pulled it off very well. Great presentation!

Great work Milos.  I esp.  liked the one point perspective view looking frpm the train drivers persepctive.

It is not easy to make complex scenes with little memory, I remember when I wore a GTX 465 1GB. Had to limit textures, etc..
I saw your video on YouTube, but not here in the forum.
Congratulations to you and your entire team. It's a great job.

Consider buying a video card top.
