Lightflow?

I’ve heard alot about the lightflow renderer. I thought its website was http://www.lightflowtech.com but I have just gotten 404 errors there. Can anyone give me more details on it, including how I can obtain it?

That is the correct URL. It worked for me. Maybe it was just down when you tried it.

I actually have a question about lightflow.
I’ve heard a lot of stuff that there would be a lfrt2. Is that true, and how comes I have never read anything about it before?

question: can one use this lightflow in blender to render? i saw something about being a python scrypt thing, so i just wondered…

thnx

yeah, blender can export to lightflow with the script at this site:

im not sure if its the latest script or not though…

yea, anyone looking at this should really give Lightflow a look at.

I was totally daunted at first because python/ code was involved, but for the great results you get, its well worth it. In fact its very easy after about half an hour, and I promise youll be hooked after you get a weekend to play around with it!

I have been getting that 404 error for over a week…and i am still getting it…

Nevermind, its working now!

they’re not there!!!1

:-? :x :frowning: :x :frowning: :x :frowning: :-?

is lightflow work like blender? you have a 3d window in the middle and you add sphere/cube etc…because if yes I download it immediatly!

Not really. Lightflow is just a renderer. No modeller.
You can however export your models (and textures) from blender to lightflow.

I think I can at least show what the new script sort of could look like. Of course I made it look better than it is (with some crayons and sticky tape :wink: ), or worse, I don’t know.

It is still not ready yet, at the moment I’m working on importing full materials plus textures from blendfiles, I hope I can make that work…

And to hannibar: you are already using version 2, Jacopo has been talking about LF3/4 for the last two years, and even about releasing the sourcecode, but sofar nothing happend yet. He might be busy with other things I guess…

WOW eeshlo!!! That looks incredible!!! :o </me has jaw dropping>

So with the new export script we will not have to edit anything in the actual script itself? By the look of the GUI and the material window, all we will need to do is hit render and watch the magic?

</me just made a mess in his pants>

Not really, if you look closely, you will see that there is a button to edit the python file. Even with material/texture blendfile import, I can’t make everything render exactly one to one, there will be differences. Only a dedicated raytracer (like Jandro’s YafRay probably) and access to Blender’s source for the exact algorithms used in the texturing procedures could solve this.

Also, don’t expect this to solve every problem, Hannibar was one of the testers, and I did not get the impression he was all that happy with it sofar. For many it is still something like export/edit/render/wait…/edit/render/wait even longer/edit/render/forget it…

Just curious. If the source is going to be opened soon I think that integrating a better renderer would be a really good thing. not that i am a programmer or anything…just a greedy user :wink:

Well,

I was among the tester and I’m quite happy :slight_smile:

The key problem (for me) is that materials handled by lightflow in so a different way that eeshlo had to invent different meanings for the sliders… once you get it it is fine, but unintuitinve… and you cannot pretend to have a decent preview with Blender scan line renderer… which is so fast.

Anyway, the script is now pretty self contained, so a LigthFlow newbie (reading both docs, LightFlow’s and Script’s) can render images without even caring on how LF works internally.

For example my Living mechanics WIP (The LF one, of course)
was made in a model/export/render/wait/model/export/render/… process,
without editing…

cooolio…I wish I had my hands on the script…the latest one…

does it work under linux too?

And when you’ll release the first version ( alpha too…)

It does work under Linux, but you will be missing MATSpider, that is why I need to get the blendfile material import done.

As for release date, there isn’t any really, there have been several times I thought I was close to releasing it (have been working on it since april), but then I discover new methods and ways to improve it, which means rewriting and testing all over again, so the release date gets further and further away.

I only released alpha versions to the testers sofar. The thing is because of these improvements, some parts change radically. If I were to release it now, and the next improved version after that, you might have to do some things completely differently and that can confuse and frustrate some people. So I want to get it as close to final as possible before I release it.

Hey Eeshlo, that looks absolutely fantastic!!! /me takes his hat off to Eeshlo.

Just imagine the results if you could implement something like this from within the Blender sources…DROOL

Are you planning on implementing this within the Blender code once it’s opened? Because that would be excellence beyond description… :slight_smile:
