    Just a little a still life experiment with IRay.

    I used a Dome with an HDRI image, photometric spotlight as Key light and the candle flames are emitters. I played with the textures, I applied various diffuse, bumps, normal, specular and displacement maps as well as used the collection of IRay shaders to some degree or other. I'm very pleased with the IRay uber base shader, you just throw it at anything and it extrapolates the existing texture into IRay, so clever.

    Now the rest of this is going to sound goofy. The Daz team really knocked it out of the park with this new render engine. I truly admire your abilities and dedication and I'm proud to be part of this community. The world needs Daz. It provides a full featured (getting more full each day) environment for rich and satisfying creative expression. This is not a trivial thing. Our lives become more commoditized and impersonal every day, Daz provides an exceptionally accessible avenue by which anyone can articulate their imagination, the more curious and eccentric the better. I started playing with Daz in January of 2013, and this play has enriched my life continually.

    Thank you for all your hard work, as well as all the incredible content made available by our PA's (I love you guys!).

    Greetings,

    Nice work Morgan. A very soothing scene.Thanks! I suppose we render what we fantasize about, and these days I've been fantasizing about having a little downtime... :)
    I see you have my robe in there. Terry cloth is the biggest challenge I've hit as far as materials go. Those have what I would consider extreme displacement on them, but it was the only way to make it have that lush look.
    Yeah, I was comparing the render to the 3Delight one in the PC+ forum, and noticed that the 3Delight render it looked more 'bumpy'. I actually felt that this version was a little better, in that respect, as it looked...I don't know...softer. Maybe I was doing something wrong with the displacement in the 3Delight version.Iray handles displacement differently. The best solution I have found is under Parameters, there is a new slider for 'Render SubD Level (Minimum)'. Iray seems to just love hi poly! Anyway, I was able to bump this up to SubD 4 without any real strain on the system. It did almost triple the render time on the robe. At SubD 4, it looks very close to the original work for 3DL. At SubD 5, it looks pretty much the same, but starts to load my system. Anyway, I wanted to get this solution out there for displacement as well as pointing out it is not a bad hit overall on render times, as long as you don't do everything in your scene at this level. I definitely want to play with this scene when I get hardware accel. up and running, so I'll try a few different levels of SubD once I've gotten a decent benchmark. I *think* I need to do the same thing to G2F, as she's supposed to be an HD character. I also need to tweak the skin, as she's not supposed to be QUITE that shiny. Learning, learning, learning...! I also need to try the Architectural mode, as it sounds like it works better with 'rooms lit by light coming in the window'. :) Thanks very much, and I love the robe! -- Morgan

    I wonder what quality do you guys render at and do high settings help to prevent fireflies?
    I have another render running, but only CPU-wise, so it will still take a while. Looks great already but there is so many fireflies still, so I wonder, if this might be caused by my settings. I do not want to have them too high as my render times are already pretty long...

    I tried it on my very simple Castle Window render from before, it took four times as long and made no visible difference. Now that scene was quite dark, so it very likely that whatever Architectural mode does just wasn't visible.

    That's a good question. I tried a render of the Medieval Village with Quality set to 1 and then 5 (which took about three times as long) and also noticed no difference. The one at Quality 1 had no fireflies though, but I'd like to know exactly what raising the quality does and how high should we go.

    I rendered at 10 and it looked really good but it took forever, so 5 is my choice now and I will see how it will look like when done. So far, it is still very grainy but I can tell that the shaders came out how I wanted... but fireflies everywhere, especially in the parts that lay in the shadow.

    Just a proof-of-concept; the only light in the scene is the mapped skydome - and notice what I had to set the environment intensity down to, to avoid blowing the sky out to just a flat white. The skydome is not included in the scene for this test - just the camera, outpost 94, and the grass plane.

    You had no fireflies with 10? It sounds like your current render will be a very good test to see how Quality affects fireflies then.

    Finally got shaders not to crash.

    Robot on left is default shaders, without touching it at all. Obviously, in Iray, the ambient channel does nothing.

    Middle robot is 'convert to Iray base' and use emitting plastic for the 'eye.' Doesn't look all that different, really.

    Third robot was originally going to be converted to brushed aluminum until I uncovered that crashing issue. After some poking around, decided to take the shaders from the middle robot and then play with metallic flakes. Just added metallic flake weight .3, .5 for flake roughness/weight/etc.

    Ended up with a rather satisfactory aluminum-looking robot with good highlights. When I poke at this for projects, I'll spend more time to adjust materials (the joints should be a smoother material, tweak the pistons, make the central ball rubber or something)

    With things like portraits, the eyes may not clear up completely depending on lighting. In that situation turning it up to 2 helps and usually clears it up. Primarily when you are dealing with multiple complex (as far as lighting goes) surfaces is when you want to nudge that value, though it is rarely necessary and it will increase your render time.

    can anyone give me a tip how i can resolve the problem with the Pillow ?
    Did the render 2 times with different Settings.

    This here is with Quality 3 at the moment and Sun only

    Looks like non-planar polys. If the Pillow is subdivided set the render subd level to 3 and see if it fixes it. If it isn't SubD then make it subd and set the render subD level to 3 and see if that fixes it.

    If you need screen shots let me know. :)

    thx for the tip, i will try it after work ;)

    Thank you very much! Yeah, the eyes are a problem sometimes, especially when a shadow falls on them, I already noticed that. If it is not too bad, I can get this solved with Photoshop, but of course I want to avoid it. :) So next time I will render with a "2" and report how things look like. :)

    Iray is progressive rendering. LOL It doesn't render other ways.

    I feel like an idiot myself. I had the same artifacts as there was on the shown pillow, so I cancelled my render.... now did those SubD settings and will then render again over night while sleeping. We are all here to learn after all... :)

    I tried it in a scene I posted in another thread (my Model Agency), which was lit with a PM through a venetian blind. Architectural looked ok, but had no shadows at all. So either it has none or (more likely), I don't know how to set them.

    Edit - Here's a quick and dirty render with architectural and one with the PM

    Okay.... I hate the fact that all of you have those fancy NVidia cards and something like this takes me half an hour to render via CPU....;-) :-P

    but that aside... see all the fireflies? If there would be 3, okay... but there is like 100? How can I get rid of this effect? I have set a sunlight, the render quality is 2, no caustics or whatever... I am a little lost. It looks promising and I like how the skin and the water come out but those fireflies really ruin it for me. I´d appreciate every help.

    Here is my second test with Iray. I revisited a scene rendered in Lux/Reality 2,5 in last year. I like so much the result and decide to give a try rendering the same scene with Iray. Take me officially impressed. There are a plenty room for improvement yet, but considering the little time I had to play with the surface settings and the new lights, I am very glad with the result Certainly my previous experience with Reality and Lux made the transition to Iray a little more easy. Lux render, which take 10h to render is below just for reference.

    Total Render Time: 4h10min
    Render Mode: Photoreal just CPU
    CPU: Mac Pro Dual-Quad Core 2.8Ghz

    I don't see any fireflies in that render. I thought I did, but I moved the window and it turned out it was dust on my monitor.

    Is this the wrong image, or is it maybe that it shows fireflies in the render preview, but not in the final file...?

    Oh I am not the only CPU renderer then, now I feel less lonely. ;)

    Funnily enough they seem to get less dominant in the final file and only show like crazy in the window where it rendered in.... that is something! There still is a few ones in the very dark areas but those are no real problem. Very interesting effect, thank you for pointing me at this! It gives me hope. :)
