Title: Covelight Effect in Lumion3
Post by: Studio4d on February 10, 2013, 10:51:49 am
Hi Morten/Remko,
I am a vray 3dsmax user. I have tried lumion 2.5 free version. its good. now after the release of lumion 3 global illumination, i think we can use it in some of our projects. there is a querry regarding lumion3, can we create covelight effect in lumion3 . for ref i am attaching an image. kindly clear the querry so that we could think of purchasing a licence.

Thanx and Regards

Rajeev

Hi Rajeev, there are no area lights in Lumion, so you would have to fake the effect with a lot of omni/spotlights.

Alternatively, you would have to bake the cove lighting onto the texture of your model in your 3D modelling application.

I thought I would whip up a quick sample of how to potentially get the cove lighting effect that you are looking to do.  I assigned an emissive quality to one of the textures imported from SketchUp to give it an overall "glow".  I then added some effects:  Global Illumination, Lens Flare, Vignette, Depth of Field, Shadow Customization, etc.  The renderings took under 10 seconds after I applied the effects.  The effect may not be perfect but it gives you an idea of what can be done.  I am sure that some of the more advanced Lumion Pros in this forum could get a better result but this should help you determine if you should purchase a license or not.  Obviously I suggest you do.  You will not regret having this amazing tool in your arsenal!

For this situation I would go with an emissive material to feed the flare effect with something maybe.
The area-light fall-off would be best to simulate with a good lightmap or place a point-light all 2m with a high-GI value and low fall-off.
But lightmap would be much faster for final movie I think and gives better light distribution. :)
I use Flatiron plugin to bake in 3dsmax. Works with any renderer and is a great plugin.

Thank you guys for the reply. Morten I have Nvidia gtx 560 ti 1 GB Card. Would it be enough for Lumion3 Pro with such walkthrough.

That's impossible to say without knowing what sort of detail level you're aiming for.

Even the simplest scene can be made very slow if you add a lot of high resolution textures, planar reflections, spotlights, video textures etc.

Does memory of GPU Matters in case of renderings/ navigation. I mean gtx 560ti 1gb  vs  gtx 560 ti 2 gb. Since I am intrested in global illumination in interior walkthrough. It would be using lots og spot lights as well as planer reflections also. Kindly suggest  a suitable (Economic) Graphic card for  such works( Auditorium interiors / Hotel Lobby, etc.).

is better to use any kind of material and apply it a EMISSIVE quality in addition to a few omni/spotlights.
