Title: old project converted to lumion
Post by: stucki on July 19, 2011, 01:50:58 pm
this is an older project which was used as a showcase for or new customers.
with a little work we transfered some of the interiour lightmaps to lumion ( which could become more userfriendly and expanded in its use . see general thread about lightmaps )

and after a night of rendering here is the result.
IIID - visuelle Medien - Musterprojekt (http://vimeo.com/26615171)>IIID - visuelle Medien - Musterprojekt[/url] from Ingo Stuckenbrock (http://vimeo.com/user4167619) on Vimeo (http://vimeo.com).</p>

please feel free to comment.
still the first days in lumion use for us ...

best regards
stucki

p.s. will there be more bushes and flowers in the near future ? bushes are needed very badly ..

Looks very good! Good job on the light maps. We will be expanding the model library so there's a big chance there will be more bushes.

I love the video for their color and brightness, without leaving the design of housing and sports facilities, perfectly matched. However, I would have liked to see the top floor of the house. I said very good job congratulations.

Remko Indeed, the forum said last week that would appear a new version of SP2 build 3 with improvements. We already know when you're going to put in the download area. I mention this because today in our download area appears only Lumion Build2 32-bit SP2.

Thank you very much

Yep Lightmaps look good and greatly increase the quality of the interior render.
Yes they could be a lot more user friendly I am still having problems with disappearing facets when exporting Lightmaps from LightUp. Lightup costs  £120 sterling, comparable to a Lumion Plugin.
 If Lumion and Lightup would talk to each other better you would instantly greatly increase the quality of Lumion interior (and maybe exterior) rendering.
See Lightmap/baked textures thread in the importing section.

@ Stucki
Great video!!!  The camera motion and speed works just great to show interiors and exteriors (not to slow not to fast, perfect!!), what did you used for settings to achieved this speed and atmosphere?

some comments: Reflections!!!!..... the water reflections and the window glass reflections are too intense and distracts. I read in a different post that you could adjust these settings in the movie settings area. check this post:   http://lumion3d.com/forum/index.php?topic=1285.0 (http://lumion3d.com/forum/index.php?topic=1285.0)

Overall, the movie is amazing!!!  Great work!!!

thanks !

clip speed is set as a movie effect to 0.3 i think.
what else do you need ?

reflection is a little bit to much, i agree. Maybe i will render it again ....

lightmaps are calculated with vray and manualy loaded per object in lumion.
but at the moment we couldnt transfer all into the project, because of the limited possibilities of lumion in this section.

if we import lightmaps into objects we cant have reflections and other effects like light emission.
hopefully lumion will improve here.

Maybe interiour lighting in version 2.0 will make lightmaps obsolet ... Cant wait to see some official material from lumion regarding this.

Hi Stuki
Did you export lightmaps from Vray for Sketchup, or was it maybe Vray for Max?
Title: Re: old project converted to lumion
Post by: stucki on July 19, 2011, 06:41:33 pm
Vray from Max

That was great....love the lighting and interior work....the dof throws me a bit but otherwise I was stuck to it....cheers!

Looks good Stucki - all the interior detail of furnishings, etc- really makes it sing.   :-D

Wow, amazing video, really good camera speed and views.

Maybe in v2 we'll get directly in Lumion lightmapping, like Beast or similar, so long as all the settings are exposed nicely in the GUI so can tweak as needed.

thanks for the feedback !

lightmapping inside lumion would be fantastic ! but i hope the interiour lightning is so good, we dont need it at all.

Lightmapping in Lumion is needed, or much better real time lighting. Importing lightmaps into Lumion is pretty tricky, and then you have to consider what they look like in Lumion, ie the Lumion sun casts shadows of its own, also Lumion doesn't support shiny lightmaped surfaces.
I am considering now rendering the interiors wholly in LightUp, with cubemaps from Lumion representing the exterior environment.
LightUp takes about a couple of minutes to produce excellent Lightmaps of pretty complex interiors, if Lumion were to be able to do this, we really wouldn't mind the 2 minute wait.
Add to that the ability to import camera paths and you will have an all round real killer application.

Specular light maps are not possible because specular reflection is a function of the light, surface and camera.  We'll see how the real-time lighting turns out. Maybe it's good enough so you won't need light maps. Two minute wait is a bit on the optimistic side for some good lighting. Light maps with a two minute wait are probably much worse than a good real-time solution.

"Specular light maps are not possible because specular reflection is a function of the light, surface and camera."
Forgive my Heath Robinson approach but, if I had say a table with a baked shadow running across it in say LightUp, if I did a screen grab looking directly downwards onto table, capturing the baked shadow texture of the table top  perfectly, then applied this in lumion onto the same table, as an ordinary texture, applied reflection in Lumion, then hey presto, you would get Specular Light Maps. This would definitely work, the shadow on the table would remain the same, but the reflection would change with the camera position.
So logically if you had a material say "Shiny Timber" on various furniture and say on a floor in a room, could you tell Lumion to make this Lightmapped material reflective? or would the original texture names from LightUp be now lost to Lumion?
Attached screengrab took three and a half minutes to bake, if you can get the real time solution this good that would be a massive leap forward.

Reflective and light mapped materials are easy. The problem is to capture a baked specular radiosity lighting solution. You can bake diffuse lighting because it only depends on the surface normal and light direction but this is not the case for specular lighting.

I think we can go a long way with real-time lighting. Once you start light mapping you run into a minefield. For example big areas don't work well, trees and other vegetation does not work well, animated or other moving objects don't work well and you can't move your lights. And as I said before you can't bake specular highlights so you wont have your lights reflecting on a table surface for example. Probably it's better if we make the light map import easier so you can use it when you need it and complement it with an alternative lighting solution in Lumion.

"Probably it's better if we make the light map import easier so you can use it when you need it and complement it with an alternative lighting solution in Lumion."
I would imagine imported light maps just being used for interiors, an easier way to import them correctly would be good, I have been playing with importing LightUp light maps for the last few weeks, I have made a lot of progress, but still facetes are missing, and sometimes the lightmaps dont appear at all, so I dont think I can rely on this for work deadlines etc.
But as you say lightmaps will have to be used carefully to avoid  shadows from say: swaying branches or walking people, overlaying the light mapped shadows.
Another thing that's got to be matched up is the sun position, for the light maps and for Lumion.
Ideally the light maps would be generated inside Lumion .

"The problem is to capture a baked specular radiosity lighting solution. You can bake diffuse lighting because it only depends on the surface normal and light direction but this is not the case for specular lighting."

Again forgive my simple approach, but is there a way to select a light mapped surface like a table or a  floor, in Lumion, tell Lumion that the Light map texture should be treated as an ordinary texture, then you can apply Lumion reflectivity to it?
Ok this would get tricky for smaller objects but the value of a glossy floor or table for realism would be great, these glossy surfaces would also reflect moving people, swaying trees etc, and integrate the sterile light mapped space into the rest of the Lumion scene.

Lumion 2.0 has a deferred rendering engine which means most materials will share capabilities so the lighmap material will probably have the same reflection options as other materials.

that sounds very promising. Can i have it tomorrow pleeeeeeease ;)

I imagine Lumion showing only the direct light without radiance until you press a button "process lights" then he will make the radiosity calculations and transform them in texture, if made changes in the position of lights or objects will need to click again on "process lights".
The lights have an adjustable radius of action.
