I believe you have something very special here, from the great clean GUI to the fast rendering, however i find it lacking on the lighting department area. What if there is no natural light coming in , for example: an area with no windows, such as hotel or building corridors, etc.  Also, what about night time shots? What can we do then? I think that for a thousand bucks, i should be able to get at least point lights and spotlights with shadows. Any feedback on this will be greatly appreciated. Smile

 

Thank you,

We focused on a daylight render engine for version 1.0 

 

If you want indoor lighting you will need to bring in your model with a lightmap.

 

Of course we will track this request very carefully since it was also a hard decision to make to not have that in version 1.0

 

But we focused on the interface and completely clear and stable work pipeline which we hoped is more important to have in version 1.0

I'd be very interested in lighting as well.

I've read various other posts on your WordPress page and understand the problems of introducing realistic interior lights into a realtime engine but I think it would be a great advantage to all of us who do interior renderings as well.

the same for us.

projects outdoor / indoor are 50 % both for us.

So lighting up indoor places via lumion would be very helpfull !

I'm currently looking at Lumion and Twinmotion.

A plus for Twinmotion is it has other types of lighting than just only daylight. (Therefore count me in for other types of lighting in Lumion)

A plus for Twinmotion is it can export an interactive exe.

A plus for Lumion is the price. Is 750Euro an introductory price. If so what will the final price be?

 

I have VrayforC4D to offer my clients photorealism. But I'm looking for is an option to offer them interactivity at the expense of photorealism however the interactive exe should have a similar look to the photos eg. a night shot or an internal room with NO natural light.

 

Thanks,

Lighting

We specifically decide not to include spotlights because it's difficult to get right and we decided we first focus on Daylight.

 

For interiors you can use Vray and export the lighting. This is lightyears ahead of anything that can be rendered in real-time. Try downloading Twinmotion and set up some interior lighting and you'll see what I mean.

 

If you export your lighting from vray you will be able to get results like this in Lumion:

http://download.quest3d.com/De.....o_Loft.exe or

http://download.quest3d.com/De.....amical.exe

http://download.quest3d.com/De....._Issua.exe

(Quest3D is our other product which is made for more complex 3D applications)

 

Maybe we will take a shot at local lighting later but we'd probably have to include IES lights and some form of radiosity. Essentially it depends on what our users want.

Hi Remko

 

Thanks for your reply. Those exe's are exactly what I'm looking for. I work with Cinema4D and I have Vray but I don't know how to do what you're saying ("export your lighting from vray"). How would I do that?Confused Would it be possible to have some video tutorials in the future showing this?

 

Also, the price is 749Euro. Is this a discount price which will increase to the normal price later? If so, what will the normal price be?

 

Thanks (and sorry for all the questions Embarassed)

In that case there's a big chance you'll see it appear in a later update :D

So there's no lightmap tool available?

Mean that you need to export your lightmaps from your 3d app and import them into Lumion?

 

This is a very tedious process, especially for interiors, since you'll have hundreds of object, to apply a lightmap to each one is too much time consuming...

 

Well, in a normal 3D app if you set the lighting for an interior you have a main light ( sun ) that comes from the window and indirect lighting that will take care of the interior lighting, however I usually use secondary light ( like plane lights that matches the size of the windows ) without shadows for secondary indirect lighting, that gives me very good results.


It will be possible to do something like that in Lumion?

Think that it will be a perfect solution, since lightmaps baking ( export&import ) requires too much time to setup, so have a tool that take care of it will be perfect.

Like this you can have very good lighting, not dynamic, but still very good looking.

 

For realtime lighting, in order to have a day/night lighting cycle, you can have a script that will control the amount of the sun light and the amount of the lights that you'll have inside the interior scene, in order to simulate indirect lighting, so they can switch off when the "night lights" ( lamps ) will turn on...this would be a fair solution

We can develop very quickly because Lumion is based on Quest3D so we are discussing to put in some local lighting for the first service pack. No guarantees but we're working on it.
