UtruMarine Ocean too grainy, and don't get me started with lighting...

wildbillnash

Okay, a while back I purchased the Ultrumarine Ocean package and now started to try some scenes.  My big problem it the image comes out too grainy when rendered.  It's also too dark so I added a plane ghost light above the scene.  You can see from the image it just doesn't come out too clear.  I also tried to play around with exposure, f/stop, etc. and no luck

Also, any enviroments I get, interior or exterior, that comes with it's own lighting always have them grouped in the center on the floor (or below the floor).  What gives with that?  I purchase the scenes and I expect the lighting be placed where they need to be.  I shouldn't have to move them around from scratch.  Sometimes they are some distance away from the scene and it takes time to move them even close to place around the scene.  And they are NOT even turned on.

Any ideas out there?

Oops, forgot the image.  Sorry about that.  (I hate getting old.)

No idea about your second question about environments and light position when you add them. That hasn't been my experience, so someone with more knowledge of what's going on with environments and lighting issues of that sort will need to address it.

As for your first, Ultrumarine Ocean is an older product, and only has 3Delight shaders. According to your image, you're trying to render it in Iray. If it has any sort of unique shaders, those may fail completely in Iray. You'll need to find some good water shaders for the ocean plane to make it look good in Iray, if you haven't already. Also, it comes with "Wave Pattern Lights', which will only be set for 3Delight, so you'll need to find each light and set it to Photometric mode, if they're things like spotlights or linear point lights or distant lights. If they're mesh lights using UberArea or some sort of emission, then you're going to have issues redoing them.

Ultrumarine Ocean is intended as an underwater environment, but it looks like she's on top of the water, diving in. So any light sources in the scene will be underwater, by design, and diffused by the water plane above them, making the scene darker than you would want, even if you weren't using Sun-Sky. About which...

You're using Sun-Sky mode. That deactivates all other light sources, so your light plane can't work. Neither will any of the lights that come with Ultrumarine Ocean. Also, if she is underwater, your Sun-Sky light is going to get hammered by the water plane above her, so it would still be dark anyway.

Apart from that .. maybe try turning Draw Dome on? In your settings, it's off. Also, what time of day is your Sun-Sky set to?

Honestly, I suspect using a regular HDRI sky rather than Sun-Sky would help some of the issues. At the least, it would mean all the extra light sources you have in the scene might work, rather than getting turned off by Sun-Sky. That said, the core issue is that Ultrumarine Ocean isn't designed to do anything you seem to be needing it to do in this scene, besides being a water plane.

Thanks @vwrangler. I made that product a while ago and it would take some time to convert it. @wildbillnash This product was created for Iray by Arki and me and it will get you some very nice results. https://www.daz3d.com/aguja-undersea-environment

Thanks for the input, vwrangler.  She is underwater, that's the sandy bottom you see below her.  Didn't know UO was for 3Delight.  Gonna have to try it that way.  Also, I turned on the Sun-Sky based on into I got in another post.  Thanks for the correction.  Will switch it back.

I wish Daz had a way to seperate 3Delight and Iray apart so it's not trial by error.  Just started learning HDRI so not too familiar with it.  More research to do.  I have no idea of the time of day, it's whatever UO is set at.

As I mentioned before, it seems all the lights are collected in one spot at the bottom of the ocean.  I have to move them into position and do all the settings to get them working.  Another project in the near future.

Thanks again to you and Marshian for the info.

wildbillnash

Yup, that did the trick.  Thanks.

I never had any use for this product even with 3Delight. It never comes out right. the only use is
the sandfloor if you add a good Sand shader to it and use it as a desert or beach scene!

This worked for me when dealing with 3Delight shaded objects.

Select the object and use the !iray uber base on it. It shouldn't change colors nor the textures used (make sure the surface is selected under the surfaces tab). Also, did you try messing with the denoiser under the render settings?

No clue about the lights tho...

Brijac, I haven't a clue what you just said.  Will have to explore and experiment to see if I can follow you.

Applying Iray Ube Base will preserve/convert settings only on shaders it knows about - essentially the default sahders that come with DS. It can't handle customs shaders, certainly not if they use different property names or simply have different properties.

Thanks for the info.  I just wish Daz had a way to label or seperate 3Delight and Iray for enviroments so we don't have to go online to see why it didn't turn out right.

You mean in-store? Generally if it doesn't say Iray it isn't, it will be 3Delight (if it has DS settings at all).

The rule of thumb about saying Iray is a good one.  It looks like the majority of my enviroments are for 3Delight.  I'm looking through my list and the only ones I can find for Iray is Easy Environments: Space and Urban Srawl collections.  Funny thing, except for the underwater one, all the others seems to work alright in Iray.  Oops, nope, just found that i13 collect is listed in the Details on the sales page, but not in the Daz program.  Go figure.

What is "DS"?  Which also brings up the next question, but that I'll save in another post.

Daz Studio - older (much older) content may be set up purely for Poser, DS will read the files but the material settings will be very basic.

Richard, thanks for the info.
