    thanks, Otacon.
    Afaik Gradients are simply Irradiance gradients, a better way to smooth GI samples. Imho it should be always ON.
    Regarding Behind Test, i never saw big differences so i never use it, but since my setup is usuallty different, maybe it could make sense here.

    bye

    Is your Ambient Occulsion, the built-in Lightwave AO raytracer, AO shaders or are you using SB_AmbOcc shader.

    What are your setting for AO?

    For this image I used the built in AO node. Settings were like 1' distance, 8 quality.

    What are your Photoshop settings, I never get clean images when I do gamma corrections... I don't get How you can go from totally black image almost to white
    Seriously, when I do so, I get overblown areal or grain.

    Wouldn't you mind sharing your photoshop workflow (in few words). Thank you, your work is very inspirational! Hav you posted outside NT forums?

    Afaik its not photoshopped, its Photomatixed http://www.hdrsoft.com/index.html

    Yeah I use photomatix, and more recently I've been messing with Oloneo photo engine. Part of getting it right is balancing your light in lightwave. Before the vpr, it was harder to see what kind of light balance you were getting. Turn off dithering in the processing panel to get rid of noise.

    I also post at evermotion, cgarchitect and some other forums.

    I'm really liking Oloneo. It has nice curve adustments, it updates faster realtime, simple controls, better color controls.

    If you want better light in bumps with radiosity gradients should be OFF, aside bump radiosity option, flicker in this case is bigger. For stills I always turn it OFF, I'm getting better details this way.

    MDspecific, thanks a lot for the info, gonna try it.

    Yikes, this looks too good. Lighting and surfaces are a treat for the eye. A friend just bought a render plugin for rendering interiors, then I showed him your renders. Enough said. I don't know why people think LW is not capable in that department.

    Why do you tonemap the renders so drastically ? Don't you use sRGB color space ? I use tonemapping just to tweak the image a bit. I get nice light balance when rendering in sRGB, can't get blown highlights even when cranking the lights in the 100 - 500% range.

    honestly i didnīt know because of ignoring the Color Space, (i guess many of us did)

    I leave "Use Behind Test" off because it's faster when off.. untill I find a problem. I'ts easy to test. using fast radioity settings put a painting with a frame on a wall, separate it slightly, Now render with, and without "Use behind test".

    When it's off, radiosity rays compute the painting but not the wall that is behind it. In this case it can contaminate the wall with the brightnes or color values of the painting, making the wall bright and colored instead of dark from the radiosity "occlusion".
