Show Us Your Iray Renders

You might try first setting it to have the right color with the emitters... or maybe just a bit on the dark side and then put a Photometric point light in or near the flame to send out more light. Maybe set the color on the point light to a yellowish orange or something.

Thanks for the suggestions. My first attempt was to turn the two planes into an emitter. I then set the color slider to the flame texture and left the color selection white. The flame showed up fine, but no effect on the environment. If I cranked up lumens, it blew out the texture.

I also tried the same thing but changed the color slider to various shades of red or red-orange. Same problem. I even tried setting the color temp of the emitter to ~2900K to get more red. Same problems.

Ultimately, I did as you suggested and created a point light at the top of the staff to actually do the light casting. I set it to an appropriate red, and you can see the results...which makes me think that obviously something wasn't "appropriate". After playing with this all evening I am beginning to suspect that in a "real world" situation lit in a similar fashion, the flame just wouldn't have that much of an impact due to the relative intensities of the various lights (skydome and meshlight front-right).

Note to self. The new headlamp switch only works, IF, I switch from perspective view to that camera before rendering, lol.

I see birdies, hmm.

ok, i played a little more with Iray and bought yesterday a new GTX 970 (My old GTX 570 has only 1,2 B VRAM :( )

The First Picture takes 1 hour (CPU & GPU) the other with only GPU around 30 min

Wilmap

Been playing with the new renderer.

Bottom image is Fiery Genesis in 3Delight
Top image is Fiery Genesis in Iray. I swapped the two spotlights for Iray ones, and use Sun/Sky setting.

Have I got it right or does it need altering some how? Opinions please.

Redid the Iray one after changing to ray traced shadows.

Here is my first render using Iray

That looks great, a big improvement on 3Delight. Super job.

Played with ART Collab Chemlab and some caustic effects ;)

Design Anvil - Razor42

The lighting is taking some getting used to, but its worth the effort.

Some great renders in the thread!

Another studio test. This one has a V4 UV on the character. The dress is the Iray silk material.

What a cool addition and here is what I came up with in a few hours. Lit only with a an indoor HDRI.

I gave it a first quick try too. First impression is very good. Lots of potential there. Not quite at Octane levels yet, but you can't beat the price. This image is a remake of a scene I rendered in Octane earlier. Render took ~15 minutes in Iray using my GTX 980 card. If I add my second card (a GTX 780ti), this drops to ~7 minutes. Not bad at all. Looking forward to see how this develops.

I will note that Iray always uses ray traced shadows.

73 degrees? Good, your cooling is doing what it is supposed to be doing. If it stays above 90, it isn't, but 73 degrees should not shorten the life of your cards.

Notice that the temp was Celsius not Fahrenheit

Celsius to Fahrenheit
73ºC = 163.40ºF

Edit for conversion link http://www.metric-conversions.org/temperature/celsius-to-fahrenheit.htmYes. 73 degrees C is within the normal operating temperature of Video cards. (Granted it is towards the high end, but it is within spec.)

Is there a way to see how long a render took to be completed besides at what time it was saved to a directory? If you just render it to a window?

It is in the log file, along with the stop condition, how many iterations were used, and what devices were used.

Riggswolfe. Impressive, can make, star-ship. lol

Is that the stock surface maps on the saucer, or all out Iray shader of sorts?

I selected plastic from the iray shaders for the hull textures.

I selected plastic from the iray shaders for the hull textures.For starships, carpaint, retaining the textures and adding the textures to the metal flake layer makes an interesting hull. :)

So select carpaint.....don't replace textures and also add textures to the metal flake layer?

This is the pearl car paint with the texture maps on both the main diffuse channel and in the metal flake channel. Lit by an HDRI, and turned on the lights with a tweaked Emission shader. Oh and replaced the glass with the thin walled glass shader. :)

Playing with the Iray specific skin shaders.
This ran for approx. 10 minutes .
Hardware on laptop is as follows:

Processor: I7
GPU (s): NVidia GeForce GT 735m ( 2gb ddr3 vram)
Intel Hd graphics

8gb system RAM

I' think I am gonna love Iray when I figure out how to better utilize it

This is a great start. You have nice eye reflection going. Maybe adjust the tone mapping a bit to brighten it up and you're on the right track. :) Well done!

Working with organics was starting to annoy me, and I remembered I had a free kitchen pack from inLite Studios. I really want to get my hands on that chess set by AoA.

Everything shaded with the iRay shaders, including the backdrop. I turned on the top-layer on the backdrop so I could get the reflectivity I wanted on the floor. Smooth spot on the front of the ladle is due to my dof on the camera, the front pane is just passed that spot. The env map is an indoor apartment EXR. No other lights, dome only, and camera headlamp is off.

Forgot to check how long it took, less than 10min though. GPU only- EVGA 770GTX 4GB FTW Edition

Now THAT is fantastic! Well done. :)

My Specs:
AMD FX-8320 8 Core 3.5GHz
2 X Nvidia GeForce GTX 650 Ti BOOST SLI

I decided to go big for my first render. The scene is from my old Luxus setup as it had the 2 light planes more or less in place with the dark grey cube. I didn't subdivide the outfit and it shows. The materials are the Iray G2F on Olympia, then just Iray Uber Base everywhere else and I set the cube to be rather matte.

This was at 44 minutes, 1875 Iterations and 92.72% image converged.

Nice :)

My try with a mammoth trapped in ice cube. About 40 minutes on a Mac Pro Dual Xeon, Nvidia GTX 750 2GB.

Stonemason's new set (part of it, anyway). :-)

All the light is from the two overheads - cranked way up. Total render time was two hours, although I didn't see any major improvement past the first hour. 6-core I7 3.5 GHz and GT 740 with 384 cores. The 740 never went over 1.4 GB and was driving two monitors as well.

Now I need to figure out where the wall lights are and crank them up a bit. . .

Nice! :)

Ok, nothing really glitzy or fancy like a lot of your renders, but I'm happy with it...

(just a Genesis figure, even, though it took some playing with Iray and looking at a G2 figure to figure out how to do it right)

Very cool. Love the effect. :)

I have had a play with the new tools and using just a hdr as the lights these are a few results:

Alessandro, did you export hair as obj?

I tried that and ended up with a 1 gig obj file that made my computer have seizures. ;)

Nope this one had no fur, but I've done some test renders with large .OBJ files coming from LAMH: I had most of the times to have IRay render only on CPU, because from my experiments, if the memory required to compute all the scene objects exceeds the GPU memory, most likely the render will fail.
