Will landscape products (like "Dry Mud Desert") work with iRay?

Hey guys,

I am wondering if this product: "Dy Mud Desert" will work with iRay. Here is the link;

Thank you.

    Everything should work in iray by applying the iRay uber shader.

    Except the write up mentions some special shader to overlay things so that it doesn't look so tiled. Depending on how that works, it might not convert well to Iray.

    From my experiences with the product the answer is no. At least, not without a lot of tweaking and some pretty decent knowledge about textures and SubD.

    You can get it to look half decent on close up shots by adjusting the tiling and surface settings a bit, but then on wide shots it will look like there are repeated dirt tiles on the ground. I've never been able to get it to look like its supposed to though, other than in 3Delight. I even submitted a support ticket about it once and they couldn't get it to work right in Iray either.

    You have to be wary about large landscape scenes designed for 3DL when using Iray. A lot of them will come out looking very wrong by default and will need a lot of work done (if its even possible) to get them looking decent.

    Edit: Just applying the Iray Uber shader will not work here - trust me! I would treat any statements that these things 'should work fine' with a pinch of salt, unless the person actually backs it up with proof.

    Heres what it looks like in Iray with the uber shader applied, and then with tiling adjusted:

    tl155180,
    So helpful. Thanks for that. That is kind of what I was expecting, which made me hesitant to shell out the funds for it.
    Given the results, it seems like these products should have a warning label on them like "not yet optimmized for iRay," given th huge difference in results.

    No worries. Personally I bought all the landscape products I have before Iray came out, so I can't really complain. They work perfectly well in 3Delight and, after all, thats what they were designed for. But it has been my experience that almost all of the pre-Iray products I have in my library that contain a landscape do not work well in Iray off the bat, so its a case of buyer beware if you intend to focus on Iray rendering. I have no idea why this is though. Personally I'm only going to buy post-Iray landscapes from now on to be on the safe side.

    That said, if you're very skilled at DS and 3D art in general then maybe you might be able to make them work well. But I've never seen anyone accomplish this so far - including Daz technical support.

    If they put a warning on product not optimized for Iray they would have to put one on most product pages, since Iray is quite new.

    The problem is that newcomers to Daz aren't going to know this kind of thing right off, so unless its spelt out for them on the product pages they're going to end up buying stuff they really didn't want.

    I haven't found many problems when using non Iray Environments in Iray. There are one or two of the parameters that need readjusting after using the Iray Uber Shader but they still work.

    This is my latest WIP, this one uses Worldbase.

    I will point out that, if you are careful about shots and setting elements, a good seamless 4096x4096 texture can do a pretty darn good job on a landscape. You might have problems with large scale shots from high elevation.

    One thing you might want to try, to really mix things up, is a combination of Bump and Displacement maps that are offset. For example, put one bump map, use Image Editor to change tiling to, oh, 400 x 400. Then, for displacement, use IMage Editor to change tiling to 301 x 301. This will make the two 'tile' maps shift compared to one another over the landscape, possibly avoiding any obvious artificial element from high up.

    (Try this with a simple plane, I think, before you commit)

    That worldbase environment looks pretty good. How did you achieve crisp realismin the sky?

    I am wondering if investing in Worldbase may be better suited for general landscape work in iRay?

    For general landscape work you will be much further ahead by investing in a product built for Iray.

    Such product may not yet exist, but new Iray products are released everyday. Other vendors are updating 3DL product to inlcude iray.

    Then you obviously haven't tried the same ones as me wink. Worldbase seems to work ok though by the looks of it, yeah. I have one or two that work ok as well, but most I have don't.

    I'm just saying that one shouldn't try to claim that all landscapes can work well in Iray because its just not true. Some can, some can't - its a lottery.

    Personally I'd rather just wait for a product made with Iray in mind. I'm happy to do just indoor scenes til then.

    The sky is the Worlbase Skydome set up with Wills Skydome settings with my own tweaks. There is also the My DAZ 3D Library\Runtime\Textures\FM_EasyEnvironments\SnowyMountains\HDR\FM_SnowyM_Sky_HDR.exr plugged into the Environment Map in the Iray dome which is also adding to it. It is then tweaked and the elements moved and parameter sliders pulled and pushed until something appears smiley I always set up the environment before adding anything else. I may turn the dome or turn down the lighting or change the HDRI but that is all.
