I'm a 3ds max user + Vray

I would like to see a demo video that shows how to export fror Max a complex model, if it's better to use the Collada exporter or use Max as exporter.

The Vray mtl converter script doesn't work very well, every material has to be tweaked.

Then I'd like to see how handle the model and the materials, how import the model splitted into parts and then reasseble it into Lumion space.

How to substitute a part with another modified in Max

How to create a complex and fluid animation with smooth movements.

 

Best regards

Hello Gabriele ( or Ciao, dipende se sei italiano :P )

 

After lots of trial and error I finally succeed to export a complete large scene from 3ds to Lumion without too much pain, even because I'm mostly a Softimage user, but since I'm doing some export from some Archexteriors DVD I'm using 3ds.

 

This is so far the best advices that I can give you to export from 3ds to Lumion properly:

- If, when you open the scene, a window pop up and ask you about the scene scale select Adopt file scene scale

- Customize>Unit setup, select Meters

- Vraymaterial script converter works pretty good for me, since it will keep diffuse texture and diffuse color on a mesh, it will not keep other information ( so if you have normal maps you have to apply them manually into Lumion ). Of course if you want to have a good looking material you have to tweak some parameters, but thats part of the job, theres no "all standard material settings in 3ds = Lumion material"

- If you want to export just some parts of your model use layers, or ( better ) delete what you don't need in the scene and save the scene, so you'll have, for example, from the large scene lots of small .max files ( bathroom, kitchen, living room, and so on… ) so you can import each "room" manually and place them into Lumion, even if now positioning in Lumion is not that comfortable, but with a bit of patience you'll do everything…My advice is, if you have a medium/small scene, to export everything into a single file, but you need to be sure that you don't want to move any mesh in that scene, otherwise save them separately

- If you want to replace a part just use the reload button ( see the material video tutorial )…by part I mean an imported mesh….this mean, if you just imported a scene in Lumion, but you forgot to add a chair, you'll add a chair in 3ds, export again and use the reload function in Lumion, so the scene will be update with the mesh you just add to the scene

- For animation you have to do everything inside Lumion ( sun/cloud settings, people/cars animations, and so on ), right now ( unless you have Quest3D ) you can't export animations and put the animated mesh into Lumion…but I think that the guys are working on it!

 

- IMPORTANT: Right now the best way to export a scene for me is using Open Collada (.dae ), it keep every texture and color properties on a mesh…I tried both Autodesk collada/fbx, but I had lots of problems due to scaling strange values.-…bad thing though is that sometimes crashes when you export large scenes, or just crash every time if you use Reset Xform, so keep that in mind

 

Ciao Wink

Hi, I'm italian but i will write here in english so everyone can understand.

There are in Lumion some hidden features....or I need a lot of time to understand its interface.

I imported a large model, then I spent a day to assign materials.

Then I realized that there were some overlapped polygons in my model that with Vray render I hadn't seen.

I imported the model inside Lumion using Max like translator.

How can I substitute the model I have already texturized with the new one?

Where is the model in the Lumion directory tree? How Lumion load the scene? Has many xref ojects or is a single file?

When I save the model where Lumion saves?

Ok, found the files!

my corrupted model was called "EXAMPLE" (for example)

I imported the new model calling it "EXAMPLE2"

I renamed EXAMPLE2 in EXAMPLE, the same i did with file other file with extension: lib, mtt, txx, lib

Et Voilà, I have the new model corrected.

 

I hope that Lumion staff will add this feature...I hate tweaking with files and renaming

I tought that the reload function was updated in the RC1, so that you can export from 3ds with the same name that you used before ( so EXAMPLE.dae ) and just press the reload button the model was automatically updated, keeping all the materials that you already applied in Lumion, and just add the model that you add in the 3ds scene...if you see the videotutorial about materials it works properly, so I suppose that should work fine...

 

By the way, pressing the Control key allows you to enable some extra features, the interface is very easy to understand, just spend 1 hour exploring all the menus...I had problems to make movies because I didn't know where to go to make them, I spent another minute looking in the menus and I found it....so is just a matter of seeing all the menus...

 

Again, use Open Collada, I had lots of problems, especially for exporting texturized models properly...

 

Directory tree, loading scene and so on I don't know....but the files are saved under a folder in documents...thats it, but the guys are working on choosing the path to save it, or something like that

Lumion saves always in your mydocuments\Lumion folder and there two sub folders Scenes and Library
