Hello Gabriele ( or Ciao, dipende se sei italiano
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
