Thread: Barcelona chair

    I appreciate those DB&W nodes you made happen, and I'll try your set up in future, that FXGuide breakdown was interesting too, particularly the color and surface guides. Injacphi, can you give us a screen shot of your lighting set up, the image still looks artificial and it's either the lighting or surfaces or both. It's a nice simple scene to try get right.

    Hi Tobian,

    Can you share the leather texture, this way I could explore what you did, because there's so many tweaking inside every box...

    my email is [email protected]

    thanks

    You're welcome, though it won't necessarily fix your lighting, it should look right in most scenes.

    So your're using Area lights, nothing wrong with them, although I would probably just use them as lights and not have some not affecting specular or not casting shadows, they probably don't need to be double sided either, but I don't think that is your problem anyway. Is there any other environment apart from what is seen, like a HDR image?

    GI settings are particular to the scene so I won't comment, I see yours is set to 300%, I rarely put it above 100% but I don't spend much time playing with my GI settings for still images either. I don't think GI is your problem either.

    I think it's all down to surfacing, and probably color space (are you using the RGB preset?).

    Your leather has that freshly varnished look that blurred reflections often have in LW renders, so sampling has to be higher to really smooth down the reflections, compare your's to the Blender render in your example, this is why I really want them to work on this aspect of the LW renderer. Also look at the material of the lamp, it has a dark edge on it, I don't know what that might be but that is one of the things that look artificial so you need to have all your surfaces correctly set up to be energy conserving and reflecting correctly, proper fresnel fall off and the rest of it.

    Basically I'm saying it is your surfaces that require more work, because if you can get them right everything else is just art direction.

    When I use the old school layers, If I've created a gradient set to incidence in the Reflective channel to get my fresnel reflections, I copy that into the Diffusion as well and invert it, this is suppose to make it energy conserving, I also don't use the specular channel at all and that effectively disables the Glossiness channel. The Ambient occlusion should only be used in post, so don't try adding it to the actual surface mix, and that's a whole other subject because you probably aren't using it anyway, but people often use it wrongly and that's why a lot of CG has that dirty grey overlay look. I'm no big expert on creating surfaces but I do seem to get pretty nice results so I guess I've slowly learned what not to do. I would strongly recommend studying Andrew Combs approach and anything you can find on energy conserving materials, you only have to take on the main principals, I can safely say that every time I think I've cracked this nut I discover there's something else I can try that might work better, it's never ending.

    It's your surfaces.

    Hmm yes and no.

    I think there's a number of things wrong with the scene...

    1) it needs a window and a sun-light coming in, and a sky dome. If you want the look of day light you need to (roughly) mock that up. For the sun light use a dome with an angle set to 0.26

    2) any additional lights you put in there to get more fill (photographers usually fake a bit of extra bounce) need to be inverse squared falloff (or the new clamped). If you have 'mystery' lights, with no shadows, you start picking up on that.

    3) as DJ said, work in sRGB colourspace. This means working on all of your colours and textures to make sure they are working right with that. If you do you'll be surprised how much bounce and fill you get from your environment.

    4) Your radiosity settings are way too low. and intensity should *always* be 100, and never use ambient light. If you rely on that then everything will start to break. It's better to just increase the exposure in post, if your render is not bright enough, that way everything is being increased equally.

    Hey Tobian can you show me how to setup correctly the dome sky, do you mean use a hdri image for the backdrop? And use a dome light at 0.26 angle?

    If you have an empty scene with the dome and some lights... Maybe something is wrong in my general settings, when I look at my render I think they are borring, what can I do to give my scene some emotion?

    Doing some tests for you, but I ran out of time. I'll post something tomorrow.
