Where Sketchup ends and Lumion Begins....

Hi All,

First post here so go easy please!

I have been using sketchup for a number of years and have imported to Vray for just rendering. That is until i found Lumion. I have become aware of the cool tools that Lumion has to offer, in particular the landscaping functions, the ease to populate model with trees, plants etc...

This has presented its own set of problems. What do i leave for Lumion?

So to give you an example. Im working on a housing layout on a sloping site. The site has many trees (some existing and some Proposed) which have taken a long time to add to the model in sketchup ( i kinda wished i had added them in lumion) Do people tend to populate modesl from Lumion? will the model be slower using Lumion soft landscaping?

Finally, the  most important thing: Can you see your saved sketchup scenes (views) in Lumion? I have to put together a photomontage and have the camera settings and camera location that i can setup in Sketchup. Can i do this in Lumion?

Thanks in advance everyone

Hi  will26

Thanks for your interest in Lumion.

Short answer:
 - SkUp -> model; Lumion everything else.
 - Where Lumion does not have the content, import.
 - Use Lumion to create the scene.

--------

..What do i leave for Lumion?

The basic concept in Lumion is:  model the main building/s in your preferred 3d modelling application.  That's where the iterative architectural process is defined in concrete terms for the main subject and that's the source model used by Lumion to complete the visualization workflow.

Then use Lumion to add the other visualization elements (terrain, world, sky, sun, weather, entourage, effects) to make up a visualization presentation or story in images and video.

So this means, use the content provided in the Lumion Library (see here) to add to your scene.  You import your building, and add the extra content required.  Some of this content is optimized specifically for real-time and Lumion, such as the plants. This is important to maintain the rapid real-time building of scenes that Lumion can do.

However, its not possible for Lumion to have entourage of every sort of object, so sometimes where specifically required, then a user can also import other models such as trees from SkUp etc.  Because those things are imported as meshes, and are generally not designed for real-time use, they can have an impact on performance, it depends on model complexity and number required in scene etc.

In regards landscape - it provides a rapid tool to do general purpose terrains up to a certain size and optimized for Lumion requirements.  This means that sometimes it is not able to meet the need for highly detailed or specific landscape requirements.  Users have the option to build their terrain in other terrain modelling tools (eg SkUp with Artisan) and then import that mesh as the terrain (providing some flexibility).

Have you seen these two videos: see videos Lumion Product Information; Introduction To Lumion 3, and What Is Lumion 3 All About.  Also there are a number of short quick video tutorials Lumion Video Tutorials.

Finally, the  most important thing: Can you see your saved sketchup scenes (views) in Lumion? I have to put together a photomontage and have the camera settings and camera location that i can setup in Sketchup. Can i do this in Lumion?

Specific camera positions are currently not able to be imported from SkUp and used directly in Lumion.  There are however workarounds that can do the job.  Also, as setting the view in Lumion is such an easy task, you can (easily) replicate views (unless they need to be to the millimeter accurate :) ).  There is currently no GUI for input of camera positions.

Note Lumion has just the one camera type - perspective 3D.

One other item perhaps of interest: Lumion has the ability to present the scene to clients in real-time.  A user can either demonstrate with the editor in what is called Theatre Mode, or provide a packaged scene (Pro version for use with the Lumion Viewer), where the client can walk-through or fly-through (the set video animation).

HTH.  Hope the answer is not too lengthy.   :-D

   Hi Will26

  I used to import almost all my sketchup landscape materials along with the landscape materials in one single import. Works well for small models but for large densely landscaped area it will slow Lumion down sometimes, to a very slow crawl.

Then  I switched & started to import just the model and a second import of all the vegetation (sometimes in several batches), placed on different Lumion layers and  used the align command to have everything placed as it should be.

 On large landscapes it is hard to place large numbers of plants as accurately as one can in sketchup. So my work around was to import the model and a second import of just the 2D plan view components  (Not the actual 3D component) and align and then hide the second import once I had had placed all the Lumion plants to the corresponding 2D view placements.

This works well for flat areas.On sloping areas it is best to create the landscape contours  directly in sketchup and import into Lumion  ( You can use Drop plugin in sketchup to place all the 2D Components directly onto the terrain. so you have them all in place to place  Lumion plants accurately.

If some plants that you are using are not available in Lumion ( yet) you can import those 3d plant models and add them to your library. But they wil not sway in the wind like Lumion plants do and will eat up computer power as they are no where near as well optimized for mass planting as Lumions plants are.

 You can not import the camers views from Sketchup into Lumion, but making the camera movements in Lumion, is actually easier and way more fun to  accomplish.

 Hope this helps, I'm sure even more advanced users will pipe in and provide you with even more  helpful information.

Kind Regards

hi,
from my experience i have to say,

at the beginning i used to think in numbers and distances (like used to do it in cad and skp)

the more you work with lumion, the more all the work becomes intuitive , 'unexact', free....

i reduced the 'exact' job to modelling of the elements only in skp, maybe parts of the landscape
and then the fantasy beginns in lumion.

step by step you even find undocumented functions ( like placing new tree on other tree and drag > the distance is diplayed for nearly exact placing. wonderful. so at least i don't miss 'copy with distance' anymore somehow.
on the other hand you must know, that for example placing lumion objects on imported terrains still is not solved perfectly (height align - peterm, correct me, if i am wrong for the latest update), but it will come for sure.

this is only an example and still lot of usefull functions have to be added to lumion,

but working with lumion really makes experimenting a fun and surprises you very often and gives you inspiration.

Let me share my experience a bit :)

At first I'll work with all architectural things in Sketchup ( Include Slope site..& road & etc. ) but not going too deep on their details maybe some shape & area of my project will do.

Then I'll start with Scene function in skp to make a story board for movie or for my perspective angle. After that I'll add material / other decoration object "only where the camera pass through" ( even skipped some background work if you're working with still shot coz PS can help you with better result & time consume.).

If your problem is "where to end sketchup & start lumion" my word will be when you know what & where's your angle of view are & after you add all materials to the scene.

P.S. I found it hard to add new materials to model after import to lumion specially in very complex model......

I have now split this topic for this issue to Materials Are Changed For SketchUp Model
