    With the PA sales I was going through all the sets and props to see if there was something I wanted that was on sale and I came across a complete White House Oval Office set. I have another that I bought at another site and it had excellent props but only half the room was modelled.  The one on sale here was the full room but no props. Marriage made in heaven! I spent some time finding other props to flesh out the room and converting textures to Iray and the lot, and this is what I came up with.  Finally a place to issue super secret orders to my spies. Also I want to make a "In the not too distant future War nerve center" version of the room which has the couches cleared out and some large map tables and comms equipment and stuff like that added. Needed a full room to do that so I'm really happy I was able to get this at a good price.

             I rendered that set with lux and Reality 2 a while back http://fav.me/d5b0g7d

    I like this; a lot of dichotomy in it, seeing as one wouldn't normally expect to find an orc reading. :)

    streets of asia in Iray, my own manual conversion

    PS the water isn't the one that comes with the set, this is a new closed mesh

    Fantastic Render! Not exactly sure what new closed mesh your'e referring too....? It looks better than anything else I've seen!

    Streets of Asia like most sets made for 3delight have a single thin mesh for water. I converted the water plane in to a 3D mesh via Blender, so it is in effect closed which enabled me to use the Iray Architectural shader for the water. The water shaders included with DS IMHO don't cut it when it comes to realism, or at least better looking water.

    Thanks for the comments people, much appreciated.

    PS the night time is a cheat. The background buildings are hiding the brighter than normal sky due to high tone mapping settings in order to get the real world light settings to light up like that. I could have thrown a dark HDRI in or just used additional fill lights and left it at scene only environment but to be honest I couldn't be bothered to mess about like that.

    That's what I figured, will have to dig up Blender and give it a try! Thank you for the response and the tip!

    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 :)

    Sorry, for some reason, the ears became the circle around the eyes. Methinks me needs some sleep.... cool

    Thanks for explaining the process. I might give it a try. smiley

    Is there any idea when nVidea will release the hair primitive, or is that a question for the magic glass ball?

    Have you tried using the Pearl Carpaint and putting the diffuse texture map in the Base color and Metal Flake colors sections of the body? (Or isn't that what you are talking about?)

    This is how it's done. Hitchcock didn't actually have to stab anybody to film that shower scene. The idea of a PBR renderer is to rely on its use of physics to arrive at a predictable result. Doesn't mean you have to reproduce reality to get your particular reality. Even today, Hollywood still shoots day-for-night shots.

    You done good!

  • SzarkSzark Posts: 10,634

    Yeah that is how I see it to. It hit home when I watched the making of LotR and how much tone and light adjustments were made in postprocessing. But this is how I have looked upon this when I started this render journey, all the software are just tools to fuel my ego. LOL

    Yes,that is what i am talking about. I tried that one on the yamaki vehicles. I'll post a render tomorrow.

    Perfection bores me. I am fascinated by imperfection (and the bizarre)

    A couple of test renders messing with HDRI and the Dome. Used Finite Dome to get rid of the grassy foreground in it as all I wanted was the sky. Reduced the size, changed the origin to move the dome round and moved the light source forward in the second image, reduced the Environment lighting and increased the environment map lighting and balanced the scene in the Tone Mapper so that the sky wasn't washed out and there was definition in the dark areas. Not the easiest thing to do even with areal camera in real life smiley

    ...this brings up two issues I have with many HDRIs:

    Lack of a "sun" (or for night scenes, "moon") that produces accurate shadows (like the Iray "sun").

    They often include ground imagery that can make them difficult to use with terrains and other environmental geometry.

    First of al I hadn't noticed the lack of shadow under his feet until after the renders but I think that is a ground problem and reducing/increasing the size of the ground or raising it should solve that. Sometimes even shutting it off works, I haven't tried yet.

    Getting rid of the ground and leaving the sky wasn't that difficult with that HDRI as it was about half and half.

  • fastbike1fastbike1 Posts: 4,078

    It's also likely that "Draw Ground" mat not have been on in the Environmental settings. If set to ON, figures will cast shadows at the 0 plane, all else being equal.

    @kyoto kid  "...this brings up two issues I have with many HDRIs"

    That would really just seem to be that the HDRI used isn't a good match for the scene. It's not an inherent problem with HDRI. Iray is still new to most Studio users ans people are just grabbing HDRI off the web without really understanding how the images were made (this info not always clear or available).

    I also think many users still haven't really tried to use the various Environemntal settings for the dome to match direction of shadows etc. We're all still learning to use the Iray capability.

    Finally these issues you mention are still present in many 3Delight renders.

    In the end, the artist is still responsible for the work..

    It is set to on and no it doesn't always show up where it should. I had to reset it in this render and had to lower the chipmunk on the ground below the image ground to get the shadows to show up in the proper place smiley The HDRI in this is one I made from one of my own panoramas which used 32 images but I still had to use a light for the sun to get a stronger shadow.

    ...however, there are some that plainly do not include a "sun" or end up blocking out the Iray sun.  I have tried various workarounds including using the Photometric Distant Light and prmitives with the emission shader but none of them produce accurate shadows like the Iray sun does.

    The attached pic is a good example, the background image is sunlit, but save for the car (for which the shadow looks more like what one would see on a cloudy day), none of the other scene elements are casting a proper shadow.

    I'm really agreeing with you, at least to the extent that many of the scenes we see are using HDRI that are not well suited to the scene as composed.

    There are still things going on that I, at least, do not understand about a given HDRI, o cannot always predict if it will work well with my composition without a fais bit of trial rendering.

    ...it's too bad that skydomes don't work with the Iray Sun.  The Iray Sun loads with a clear blue sky that includes a horizon gradient.  Why can't someone simply make dome backgrounds that have different cloud/sky effects to work with the Iray sun?

     I have had some luck using just sky back grounds and other stock photos back ground. thy don't even need converting or anything, and they work with the sun dial preset.  with the right backgrounds they can look as good as a HDRi

    ..however if you are using reflective surfaces (like glass, chrome ot polished metal) a flat photo backdrop does not provide anything to reflect.  Also you need to make sure the gamma of the photo blends with the scene lightiing or it will look like a "matte backdrop".

    We simply need 360º sky HDRIs with an accurate sun.at different elevations like Dreamlight did with LDP.  Is that too much to ask?
