    Looks like you are right. I must have got mixed up somewhere.

    Thats good to hear! I was starting to worry that I had lost my mind since Iain and 3DGFXStudios were agreeing with you.

    I just don't like luminous polys. Area Lights give much better results imho.

    OK people arent reading whats being said and there is some confusion

    Otacon was using luminous polys because the polygon appears in reflections, giving you nicer realistic reflections on your objects.

    I showed him how to use area lights to light the scene, while maintaining the reflection from the luminous poly, but disabling light cast from it.

    He didnt think it was possible to do this in lightwave because he misunderstood how the "unseen by radiosity" flag works (and you agreed with him here http://www.newtek.com/forums/showthr...96#post1145196 )

    He thought that the luminous polygon still casts light when "unseen by radiosity" is checked... it doesnt

    Thanks. Here's a shot of the GI settings and linear workflow panel.

    Well, thanks but I think I'm following the discussion fine.
    I didn't agree with anything to do with "unseen by radiosity."
    I stated that I use Imageworld with Area Lights so that openings appear to be bright light sources in reflections.
    Luminous polys would do the same thing as ImageWorld but I don't like using them as light sources. They have their purposes but in real world (or photographic) terms, I feel they are more akin to bounce cards than natural or artificial lights.

    Jason, are you using occlusion on the wall/floor junctions etc?
    I think that's where the nice painterly feel is coming from as it's so soft but still very nicely defined.

    Yes I did an occlusion pass and layered it in post. It adds a bit of shading, but take a look at the images I posted on page 1 that show the tonemapped render compared to the final. You can see in the middle image (without AO pass) that the corners still look pretty good.

    I see. Please accept my apologies. Of course this method is only good if you have openings and it still contributes to light being cast.

    Using a luminous poly for reflections will let you simulate the reflection from lights (lamps, downlights, tv screens etc) in a more realistic way than regular specular.

    Anyone looking at the high quality of your work understands that you dont need my advice anyway

    Not at all.
    I'm always keen to learn new things-discussions on subjects like this are vital for all of us, as are inspiring threads like this.

    Brilliant work! And a great ambassador for the lightwave render engine!!

    Awesome, you're floor surface is great.
    How long did it take to render? What were your antialiasing ans GI settings if I may ask?
    I always thought LW could not really do that in a decent time with lumipoly

    Thanks. Render time was about an hour and half for the full shot, 30min each for closeups. GI settings I posted on this page. AA was 9 passes, .038 adaptive sampling, .18 oversample.
