Fixing the sky for item 22811 Summer Island

Hello all

I recently purchased item #22811, which is the Summer Island.  Overall this is a great pack and I am very happy with it, however the sky doesn't look anywhere near like the photos for the product do.  It looks very white like and washed out.  Please see attached:

 

It looks awful, like it is overexposed.  Is there any way to fix this?

I am on Iray, BTW

Thank you,

Geo

    I think it probably has only 3Delight materials, and the sky background may well be set with ambient strength non-zero so that the conversion to Iray makes it glow. You probably want to remove the sky for Iray.

    There are a couple of things to try in Iray depending on how the image is loaded.

    According to the product page for Polish's Summer Island, it is Iray enabled / optimized. I think we'd need to see your Render Settings -> Environment tab to see what's going on. I suspect one of the values for the environment map is turned up too high.

    Edit to add, the product page also says this:

     For this scene, To get better render result, it's recommended to use Sun and Sky environment mode in render setting.

    Although its optimised for Iray it doesn't have Iray shaders used for most surfaces.

    The sky is a background prop not a HDRI

    I thought it was a prop :) Click on the image for the diffuse, go to edit image and change the gamma to either zero or 2.2 and see if that helps.

    Actually this is a newer pack and it is for Iray,  and it recommends to use the Sun and Sky setting only, which I am using.   The sky isn't a dome but a curved panorama that is in four sections, I guess they did this so you can remove a section to place a camera for a long shot.  The top part is totally open and allows the default enviroment controls skydome to be used.

    I used the default settings and yes, I had it set to Sun and Sky.  Pretty much when I do any outdoor setting I set it to this anyway.

    That is interesting.  Why would they claim it is for Iray if it isn't using Iray shaders?   Yes, the sky is a panoramic backdrop that encircles the ocean area.  Even though the sky in the sample shots for the product isn't really the greatest looking sky, it still looks better in the sample shots than what I have.  The tone mapping is set to 13.  I tried to go higher to decrease the exposure, but then I start to loose that nice brightness you have from a sand enviroment.   As it is (at the default of 13), the set is perfect.  Even the water looks great on this one with the waves breaking and rolling into the beach.  This has quickly become my favorite beach setting because of the shoreline alone.  But that sky...it looks white and not blue and the clouds are washed out at best.   I have not tried the dusk settings yet as you can do a sunset, but I am sure that is going to make everything dimmer, which is not good for the scene I am trying to create.

    Ok, I will give that a shot and see what happens.  As it is, I just wanted to affect the sky and nothing else as the rest of the scene is fine.

     

    OH!  BTW, for anyone interested... I didn't like the water color either, it didn't look right as it was too bright blue, but this was an easy fix.  I just changed the water color for all settings to a greenish blue which looks more accurate.  I can post the exact settings if anyone is interested.

    Thank you!

    Changing the Gamma for the image in the editor wont affect the overall Gamma set in Tone Mapping, leave that at 2.2.

    It won't?  Then what I could I do with the sky backdrop to give it more of a sky blue color and make the clouds look better?   As it is, I only want to alter the skybackdrop and nothing else as everything else is fine.

    Thank you,

    I have noticed that the Gamma setting is set to 1 in a lot of images used in Studio and Iray adds a gamma of 2.2 to them which makes them a Gamma of 4.4, which makes them very light if the Gamma of the image is actually 2.2 already. When the image is rendered it is set to one and then the Gamma setting in the Tone mapping is added which makes the image light as it is then 3.2. (I think). If the Gamma of the image is set to zero or 2.2 then Studio ignores it and then the image is rendered at the Tone Mapping Gamma which defaults at 2.2.

    Is this set is for 3delight. & if so you will need to make it iray compatible & properly best to remove the 3dl skydome and add a iray HDRi skydome instead  or convert  the 3dl one to iray (Instructions in another thread https://www.daz3d.com/forums/discussion/325991/poser-skydomes-would-these-work-in-daz-4-10#latest)  other wise you will get bupkis for light using 3dl sets in iray .  older 3dl sets need to be convert to iray and reworked . If its a iray set you may need to make some adjustments to your lumen & light source settings

    The gamma setting in Tone Mapping isa pplied to teh final output; the gamma setting for an image is inverted during render to get back to a gamma of 1. it's true that if a gamma of 1 is applied to an image that should be set as gamma 2.2 then it will be passed to the render as the gamma 2.2 colour, and then that will get the final gamma aplied to it, which will lead to overlightening. Gamma 1 is no adjustment, and is the desired state for processing - gamma > 1 lightens the midtones, gamma < 1 darkens the midtones.

    That hasn't been my experience @Richard Haseltine. Setting it at either zero or 2.2 and no Gamma is added or at least it is added to the zero making it 2.2, leaving it at 1 and Gamma is added making it 3.2 making the image washed out, then it is stripped back to 1 before the Tone Mapping  Gamma is added making it 3.2. I have tested this on a few images and it comes out the way it should. it is always the first thing I do when I see a washed out image like that, or if it is an HDRI in the Iray Dome I set the Dome Map to 0.5 or even more to darken it back to the original image. The HDRIs in Terradome3 are the worst for that.

    A colour image will almost always need a gamma of 2.2 (0 should usually set that). If it is given a value of 1 its colours will be taken literally and so will be too bright in the mid to upper range.

    Hello guys,

    I played around with the Gamma setting in Tone Mapping, however, it affects the whole scene.  What I needed is something to affect just that piece of sky.  As I mentioned above, the sky was the only thing I am having an issue with, the rest of the render looks fine.

    So I decided to play around with a few things myself since if I messed something up, I had four sky panes to work with and I could go easily back to the other settings.  When I went into the surface settings, the thing that stuck out the most to me was the base color.  It was set to white and looking at the image...well, it was white.  So I played around with the settings to give it more of a sky blue look.  I eventually settled on  0.0006, 0.45, and 0.65 for the three color settings.   Bam!  This did it!  Not only did it give me a better looking sky color, but also the clouds were not over exposed anymore and they look...well, like clouds now!

    I mean I just was arbitrarily playing around with the settings and ended up fixing it that way.  LOL!

    Thanks for the help though.
