Reimagining of my first ever render

Man...  that's REAL nice

I used an HDRI with the Emmisive lights on this one.

...the first two look really good.

For some reason though I'm having a bit of trouble getting emissive lights to illuminate a scene using Stonemason's Streets of Old London. The light fixtures in the rooms do appear as if they are turned on, but no light seems to spill through windows out onto the street (and I am using the Thin Glass shader).  I have them set to 50,000 lumens   Also tried 150 W and still no light.

 

Is this what you are aiming for?

...I tried those settings and no surrounding glow.  Only the fixtures themselves "light up" as if I simply used the ambient channel in 3DL.

 Everything else was left at default, I didn't even change any shaders. Did you turn of the dome in streets? Also turn the environmental map to zero but draw dome which gives the black sky and have  it set to dome and scene.

..yes I deleted the skydome that came with the set.  I am using one of the Skies of Economy HDRI's to give a little backgound sky detail instead of it being pitch black.

Fishtales

Perhaps there is too much light coming from the HDRI.

A test render for my new Koala model, rendered in IRay.

Wow! Absolutely fine.

That's really too bad about iRay.  Just another nail in the coffin for my needs then.  I hope NVIDIA is aware of this and with their coders how long would this take to make and update their rendering engine?  Of course then there would need to be an update to DAZ's version too right away....

Fabulous and very realistic render there Alex! 

Thanks a lot Richard!

I agree this is the best animal fur render is have seen come out of any hobbist program. I would have used a little anisotropy though just to give it that extra kick of realism. But still an awesome render. Btw out of interest how big a file did the OBJ fur come out at?

Thanks, I'll try to experiment with anisotropy, to be honest I didn't lose much time on the IRay materials. Each koala fur is about 600MB...

Cool! Is this the new Iray LAMH on the panda?

Nope, until nvidia doesn't add a hair primitive to IRay, the LAMH fur has to be exported prior to render. I usually prepare the scene, posing the models as I like, and as I'm ready to render with IRay I just click the "to .OBJ" button in the LAMH Pane (or if you own the full version you can export from there as well), which converts the LAMH strands into actual geometry. Once this step is done, I tune down the glossy values in the fur surface, and render. It takes a little extra work but I like the results. Of course as a hair primitive will be introduced in IRay, we'll update LAMH to use it. Oh, it's a koala BTW :)

...wow, incredible.  I can almost hear the voiceover "I Hate Qantas"

Considering all the fur has to be converted to geometry, must take a fairly hefty system to render on. 

Hello, even with two LAMH models to be exported, each set at 600K hair, the export process was quite fast on my machine (Mac Pro 2009, 24GB, Dual Xeon) and took no more than 5 minutes and a memory usage within 7GB. After that I rendered with IRay only on CPU (I am equipped with a ATI Radeon), and it went on for about 1 hour.

First Window 10 render.

V7 relaxing. I´m also experimenting with the skin shader at the moment.

Well done, the skin looks perfect!

Sweet thanks for the file size.

I'm having an issue with reflections... anyone know what I can do about this?

I'd prefer not to have to oversample (IE: render it twice as big)

I was experimenting with a space scene using the 3Dlight render engine.  I had to do quite a bit of post to blend 2 scenes together.  It's the earth half lit by the sun, with the other half in darkness from space.  You can see city lights at night on the dark side.  I managed to get the crescent moon to match the earth pretty closely.  It's still rough, but you get the idea. 

Then just for the heck of it, I thought I would make the necessary changes and see what it looked like as an Iray render.  It's not the exact same scene.  Had to basically start over from scratch.  The moon is wrong, etc, but still.

This is what I ended up with.  Considering the possibilities from here...

I'm sorry William, I'm not clear on what the issue is. Graininess?

Tjohn:
If you click on the image, the edge of the reflected person and a pole looks bizarrely serrated. I don't know if that's an issue with the light ray modeling fidelity or the surface (although given the way it looks, I'm inclined to think it's the light rays).

 

I ended up changing the layout to hide the problem, and it looked better anyway, so yay.

 

Here it is, To the Sun, using Ocean Wide (for the, well, ocean), AtmoCam for haze and skydome, and assorted bought and free Egyptian stuff.

Oh I see. Very good render. Yes, to notice the serration, I would have had to know what the unreflected object looked like.

Took the previous scene, tweaked it to be a desert scene.

 

I also Zombified the figures, but it didn't really look noticeable.

...it's a night time sky so it shouldn't produce much light. The HDRI is actually intended for use with Reality, and would use a low intensity version of Reality/Lux "sun" for the moon, which wouldn't work in Iray.

...update.

Removed the HDRI, truned off the Iray Sun, set Draw Dome ro "off" as well and the scene rendered totally black save for the actual meshes the Emissive shader was applied to.  No lighrt was cast on otehr parts of the set at all.

It might still be getting too much light. What I did in another render was change the black to a midnight blue which gives colour without the light. I'll see if I can do it with the last render.

Not as fantastic most of the renders I've seen. But i'm really enjoying Iray

I just did a quick render changing onlt the sky colour.

Deep Blue

 

More greyish than blue

...kind of what I get, but none of the windows light up and no light gets cast on the street/pavement.  The only other option I can think if is placing primitives inside where the lights are and applying the emissive shader to them or just simply using photometric spots.  That sort of feels like going back to the 3DL technique.of placing separate lights around the set which is a real pain. I thought that was what mesh lights were supposed to eliminate.

Fishtales

All I did was click on the building; go to surfaces; find the lights and add the Emission shader; edit the light to 100 Watts/15 efficacy. For the lampposts I clicked on them; go to surfaces; find the glass and add Emission shader; set light to 150 Watts/15 efficacy.

kyoto kid

...that's exactly what I did as well.  If I look dead on I can see the lights in the interior, but when I move to even a slight bit of an angle and they turn completely dark. Tried it with both the the the default Iray shader and with the Thin Glass shader applied to the windows.   For the street and exterior  lamps, all I get is the bulb to glow again as if I turned up the ambient channel in 3DL.

 

..ach it's after 02:00 here geting a bit punchy.  Will look into this more tomorrow

Fishtales

Right. I added a new camera looking back. Nothing else changed: the brightness on the wall on the right is coming from the lamp above the door because I need to change the f/stop on the camera. As you can see the interior lights are still visible. Everything is a bit slow ATM as I am also working on a render in Bryce 

Fishtales

OOPS! The bright light is coming from the headlamp on the new camera which I forgot to switch off. I adjusted the camera perameters in Tone Mapping too in this one.
