Can anyone tell me is there a way to make a linear light or to tweak a material to look like a linear light and to direct it to the ceiling? I've tried with Overbright and Emissiveness, but it doesn't light the surrounding. It just glows.

I need to make something like this. Any suggestions?

Thanks in advance.

Lumion doesnt have this kind of feature, yet.
only solution is to have an emissive material for the light material and use many small point lights for simulating the desired effect ...

The facility has not yet provided in the program but there is a way if you want to create such effect then go rational try some short points.This may help you what you were looking for.

You can make a map luminance to the ceiling in Photohop. save the alpha channel.
In Lumion, you can select and assign this material luminance :)

Excelent tip. Tnx a lot. Btw, how did you managed to make shiny aluminium not to be black in a night scene?

You just put the sphere of reflection within the environment.

If you have questions I can best explain

Glad someone figured this workaround out!
When you apply this material are you applying to the entire ceiling or a separate plane just below the ceiling?  If a separate plane how do you get the edge to fade to transparent?
Can the texture be made to see through to a wood ceiling?

Thanks,

The plan below is because in practice, there are hidden lamps.

Yes to apply the effect to just use the wood texture in channel "difuse"

Thanks for the great tips.

Honestly the fact that Lumion doesn't have linear lights yet, is a bit of a hindrance for us to buy Pro.  We are ready to pull the trigger but need to confirm I can get linear lightcoves just like your example.  Our architecture firm: Smith LaRock (www.slarc.com - Look at our first image on our homepage.  That type of lightcove detail is what we design in a lot of our control rooms) specializes in 24/7 Control rooms and a lot of our lighting on the ceiling is specialty cove lighting. 

Gilson, I too would greatly appreciate a step by step instructions if you have a few minutes to spare?  In the meantime I'll play with it in Lumion Free until I can get it, we may not buy Pro.

LUMION STAFF - Is this or will this be a reality anytime soon!?

Thanks,
Lorne

Hi Lorne, we tend not to comment on what may or may not be implemented in future versions of Lumion, in order to avoid disappointment. The reason is that technical problems sometimes prevent the developers from integrating new features, and imagine if a customer buys Lumion after we tell them that feature xyz will be added to a future version and this fails to materialise.

In other words, you'll have to work with what is available in the latest version of Lumion, i.e. IES spotlights and 360 degree omni lights.

Gilson's approach is to add a texture as outlined on the screenshot - however this requires access to Photoshop as well as some knowledge about texture mapping.

Is there a particular part of it you would like more details on.

By the way, Lumion Free is a bit outdated now but you can request a time-limited but fully functional version of Lumion Pro 4.0.4 from your local reseller.
