Something completely different!
I had to make a small webmovie to explain the tidal energy concept of my employer.
Since this is a floating device, realistic water was of great importance! That is why my attention was drawn to Lumion.
The model featured in the movie is a generic model due to legal issues.

I used Lumion 3 PRO.
The animations of the models were done in 3D Studio max 2013, making use of the fbx export to Lumion. The 3D models are made using SolidWorks. Conversion to Lumion and/or 3D Studio Max was done with SimLab rendering (which works excellent!).

Post processing was done with Adobe Premiere Pro, After Effects, and Photoshop CS6.

I took me a while to create the scenes in Lumion. Not because Lumion was slow. More due to the fact this is completely new for us and me in particular.

Normally we would have used 3D Studio Max with Vue to create the skies and water. Compared with that worklow Lumion really shortens the time to create a simple animation like this.

Rendering 720p30 took quite long due to the bad PC I have (thanks for the benchmark test).
But also there is no option to cue jobs like you can in Afterburner (for 3D Studio Max) or Task Manager in SolidWorks. That would have been a great addition so I could render scenes at night and in the weekend.

The biggest problem I run into can be seen in the opening shot. I used scale 1 to 1, so the island (which should have been a coastline) is limited by the 2 x 2 kilometer land boundary in Lumion.
Next time I will scale the scene making use of Simlab during the conversion to fbx to 1:10 or something.

The underwater scenes are also scale 1:10, otherwise the visibility is quite realistic up to 10-25m. Too less for these animations.
The model features measures approx. 60 x 35 meters.

Originally the island was a bay, which kind of cloaked the 2 kilometer limit. But a bay area is quite odd for the scene I had to create.

Any other suggestions for creating large pieces (low detail no problem) of land are welcome!

Hi Michiel

Thanks for sharing an interesting and different use of Lumion project.

re:

As a licensed commercial user you can post items to the Wishlist Boards, which are more closely looked at by the dev team.

Some users will just set the movie to render at end of day, but of course there is no control over timing as in After Burner etc.   Use of something like Windows Task Manager unfortunately won't help as Lumion is not hooked to allow for the action to kick off a movie render.

Land mass which is larger than the 2048mx2048m Lumion Terrain, can be modelled and then imported as a mesh using the Add a New Model.  This does not allow for editing with the Lumion Terrain tools, but within the 3D modeller used, and any changes are the same as for other models by using the update model and reapply materials update feature.  The world size is 43km radius, although content to that extreme is generally not advisable due to some other limitations.  

Some users do this using Google Earth terrain modelled and imported.

There is also the option of importing a heightmap, but that is limited and scaled to the Lumion editable Terrain 2km size.

I might just do that very soon! ;)
I have to use multiple scenes to create a movie like this one.

For now my workflow is just as you describe. But that means one scene a day!
I am facing up with "render" times up to 4 hours for 20 seconds/600frames of 720p30 3-star quality movie.
Luckely I will have an extra remote PC very soon and an extra Lumion license to generate the animations. But for the future this would be a great option!

I will have Vue 11.5 soon as an add-in for 3D Studio Max.
However, Lumion itself is a very powerfull scenery creator.

I already experimented with mixing Lumion terrain with imported meshes.
But I miss alle the paint and shape options to make it really look nice.

Some users do this using Google Earth terrain modelled and imported.

I noticed that. I have to look into that, since indeed the use of real terrain will be a thing I have to do soon.

Hello Michiel.
Congratulations on your work. A beautiful technology, very well explained.


----I always use features terrain mesh imported (as quoted by Peter). I think it is the best option for large areas.  Attached an example of 40x40Km.

----To reduce the render time, when the final video will be 720p, I usually do the render in 1440p - 2 stars. I reduced the resolution when video editing.
With this I get a result very close to the 3 stars, but in a much shorter time.

I have seen it beeing mentioned on the forum before, but what to use (software and workflow)?

+1 for that!!!

Many thanks!
You saved my day!

I finally have the new PC available with a Nvidia Quadro FX K4000 Graphic card, which really is a big improvement compared with my previous machine.
However, still a long time to render the complex scenes.

With your trick it saved my more than half the time!!! ;)

I use Max

The source of the file must be the center.
The texture of the bigger picture needs no resolution in high definition, as will be seen from afar.

Thanks Gilson!

I can stitch pictures in Photoshop, no problem.
But in order to get the terrain from Google I need to install Google earth + Google Sketchup as far as I understand?

I found this thread, which might be helpful.

I will try to go into this. This is an very interesting option!

I usually just use Google Earth.
Adjust the intensity of the land "0.01" then I edit in Photoshop numerous screenshots. To compose a great picture with good quality.
The mesh of the surrounding region, I model in "max", using reference photos, or simply applying "noise"

For my application some details of landscape and especially sea bottom near the coast is mandatory. I do not need it for measurements, but it would be great if it comes close to the original land structure.

I have seen examples that you can insert terrain height information in sketch-up. I will have a deeper look into that soon.

But I will keep your tip of modelling the terrain in Max as a possible back-up solution!  ;)

I am clappping my hands for you! This is so relevant to show many of our resellers that also sell CAD solutions. They have customers in this area, and will be most impressed when I show then how Lumion can be used to showcase these kind of projects.

Thanks so much for all the info and for the great video.

Thanks to Gilson Antunes to share his great insight with earth modeling :)

Cheers!

Indeed there is potential outside the "architectural" industry for your software!

Unfortunately I cannot show you other stuff I made already due to legal matters and competition. But it is amazing what I can achieve in so little time! Especially when you take 3D Studio Max as a benchmark!

A lot of applications do not require a very high photo realistic level of detail.
Especially in this area it really outperforms Max as a render tool.

It would be great to have another 3rd party software to create the fbx files with baked in animations. This could save the big investment into Max.

Keep on developing the software! ;)

Hi! Did you remove the video? I planned to show this case to a potential Lumion buyer, but it is not found.  :)

No, a new version (different text, nothing changed to the original movie) was uploaded with a different name.

I have corrected the URL so that it works again ;)
