Title: Buildings render image without background / Alpha channel tool
Post by: pierre olivier on November 29, 2011, 03:57:50 pm
Hello,

Don't find any replies in the search engine concerning my question... ???
 Is there a chance to have the possibility  to render a building or a scene image without having environnement background (no sky, no ground ... but trees, piece of ground  8)) like an "alpha channel render".  (i have in mind the option i have in Octane which is great ... but i would prefer have it in Lumion ...). Coud be useful inside website presentation or in printing job.
Having the possibility to render interior scene in Lumion V2 makes me think (more) again about this function ... to make "floating" interior scene image presentation on the web (with a shadow) or on paper. A real plus for us.

Thanks for your reply,

Pierre, architecte.

PS : Having an alpha channel video outpout mode could be great too .... of course

Hi Pierre, it is currently not possible render a model with an alpha channel as on your screenshot.

However you can relatively easily add a black background and floor to your scene:

There is a whole thread about customizable backgrounds - so you are not the first and you won't be the last to request a built-in function in Lumion that would let you customize the background, Lofts :)

It is not because Ferry and Remko don't want you guys to be able to render your models with customizable backgrounds (and in other styles), but there are just too many things on their plate at the moment. Have patience...

Hello,

Maybe i find a quick solution  ;) ( i hate having building project lost in huge green desert in the middle of nowhere and sometimes i don't have time to create a Big Lumion environment) to have an abstract environment :

- 1 Choose an empty/flat terrain with snow + possibility to create green/grass patterns.
- 2 Depth of field function with F stop to blur background.
- 3 Use a little of Bloom effect to make desapear the horizon line which has been created before (i don't understand why ?)
- 4 Put your model in a grass circular circle;
- 5 You could add white smog effect on the snow/grass perimeter to blur limit.

The only tool i need now is a perfect circular camera view ...

Result isn't so bad to present a building quickly .... in a clean white environment.

Post a video in a couple of minutes.

Bye,

Pierre

I've thrown some wild backgrounds together in Lumion. 
I don't want to show anyone cuz they were silly tests and i deleted them.
Whatever picture you can make can be the background.

Nice Video
