    That is a good idea Morgan sounds as a cool challenge

    Oh my gosh! Talk about revitalizing an older set...

    That's what we should start up; a thread of finding really low SKU models/sets (that one's not THAT low a SKU, but it's from March, 3 years ago, IIRC), and what kind of tweaks we can do to make them look great in Iray! That'd be kind of a blast... :)

    Thank you Morgan.
    That sounds like a great idea, I want to have a go at the Dystopian Console Station. It is really an awesome model for the price.

    ...Yes, the speed of light matters!...

    Actually, it's not speed of light yet but speed of electrons as that is what carries the bits between the processor and memory. HP and others are working on optical busses right now (back room stuff) where it will be the speed of light. Related to that, they plan on doing away with the whole thing of cache memory, video memory, main memory *and storage, making it a 'unified architecture.' One memory/storage type to rule them all' as they say. This they point out will alleviate much of the core purpose of an operating system since much of the core of an operating system is to act as traffic cop to the various busses, who gets access to what when etc... In their presentation they were saying they could trim as much as 80% of the core of an operating system by going to this architecture and it would be not only simpler and faster but more robust with the removal of some very complicated code that tends to step on it's own toes.

    This is the only part of a larger presentation they did before on the topic. The rest I can't find online anymore. Maybe they were being overly optimistic for the near future in that presentation, who knows. I'm guessing that eventually that is where we might be heading though. ;)

    Iray by default is set to compress textures it sends to the video card. If you look on the advance tab of render settings when Iray is the selected render you will see the "Texture Compression" boxes. The first box sets when medium compression starts. The second when high compression starts. Certain textures like normal maps are set to never compress, but the rest use these thresholds compared to their greatest dimension. By default they are set to 512 and 1024. So texture smaller or equal to the medium threshold don't get compress, textures between medium and high get medium compressed and textures above high get highly compress.

    Thank you for this information, it is very helpful.

    I will look at my settings and place a light behind the head to have more control :)

    The "virtual memory" is the shared memory some Nvidia cards have (giving access to 2 GB on the card and 2 GB of the system RAM), but Iray can only use the memory that is on the graphics card. So the Nvidia Geforce graphics card that I currently use, with 2 GB on the card and 2 GB dedicated system RAM, can only use the 2 GB on the graphics card when rendering.

    Which is important to know, and understand, for many of the new Iray users, because there are lots of graphics cards like that out there, cards that in many cases have been advertised as having 4 GB of video/graphics memory.

    Can you put up some links that show this? It would be helpful to me. Typically, video cards used either virtual or onboard memory, not both. I have not seen an instance of where one uses both yet. Thanks.

    One of the key points not being discussed re: texture maps in memory from what I can see is how advanced shaders can do away with any form of traditional texture in many cases, and cut down the textures to basically dirt and scratch type overlays in many. Using bricks in a shader network for albedo, sss color, even noise/cloud bricks in place of displacement/bump maps in many cases... I haven't had a chance to test out the memory implications of this yet as I'm holding off on getting a new system and am tied up with other projects at the moment, but I am curious how using up-to-date techniques rather then just texture mapping everything the way it has been in an outdated workflow, would impact both memory and speed.

    That's the Central District Subway, which has an underground portion that has probably seen more render use than the above-ground portion. :)

    I joined just a few weeks before that was released, and I think it was one of the pieces that led off my first March Madness, which is why it sticks out in my memory...

    Yes, as Cypherfox said it is the Central District Subway, there is also an expansion texture set Foreign Kisses.

    I've noticed if I don't visit a thread I'm subscribed to for a while, it seems to forget me, even though others are making new posts in it. :)
    After I visit the thread, it will remember me for a while whether I make a new post or not.
    It's probably an undocumented feature. ;-)

    No, it's a documented feature - it won't send you an email after the first reply until you visit again. You can turn Smart Notification off in your profile and it will then send an email for every post.

    Don't know how I missed this (and apologies if it's already been posted), but there is an Iray benchmark for the Nvidia GTX 980 Ti at Tom's Hardware:

    http://www.tomshardware.com/reviews/nvidia-geforce-gtx-980-ti,4164-10.html

    As expected, the 980 Ti is just a sniff behind the Titan X in performance. Trend repeated in the other GPU accelerated render programs. Way ahead of the standard GTX 980.

    Absolutely cracking card for Iray rendering.

    (plus interesting tidbit about new Iray plugins)

    Not this angle, but yes we did find time to meet the challenge with the wide angle lens ;-) And if one doesn't know where to find it, just ask SickleYield :coolhmm:

    First Iray render :) Hmm looks better bigger. Needed to render approx another 1/2 hour.

    I think it looks really good. The darker scenes always take a lot longer to render, but I love the drama of the darker images.
