Best WATER Product or Technique for IRAY?

Water for things like swimming pools, man-made ponds, bath tubs (not so much for oceans or running water or fountains or rain).  What's important to me are the qualities of reflection, refraction, an surface texture.

Thanks!

    I have Easy Liquid - Custom Liquid Shader and Presets for Iray, https://www.daz3d.com/easy-liquid-custom-liquid-shader-and-presets-for-iray , and I like it. If you want I cant do a couple quick test renders to see if its what your looking for.

    DS comes with a water shader, does it not? I imagine that has appropriate reflection and refraction values already set. Clear water is not so much a very difficult material to model.

    Thanks - I took a look at the link.  The image of the woman standing in the pool - there is no wave distorion on her legs.  There is turbulance on the water so her legs should have a maybe slightly wavy edge.  It looks like the water effect is on the surface of the water.

    You should consider both thin film and volumetric shaders, as the latter can in some cases look better for large volumes of water, like pools. It is good to have a range of shaders to try and and pick the one you think looks best in the render you are working on.

    Im pretty sure that you can adjust that setting with the packaqe but ill check for sure.

    Agent unawares is correct. There are a few native water shaders in DS.

    I don't know about best, but my free shader pack includes a few water shaders.

    +1 Will's water shaders are awesome!

    I couldnt find that option in the easy liquis package. Im not sure how to do it in daz either. There are presets for refraction weight and aberation.

    To get a realistic distortion in the water, you will need to modify the surface mesh or create a displacement map so that the water shader can do it's work accurately.

    And make sure that the caustic sampler is enabled...which will increase render times, but does add quite a bit to a water render.

    I really like the ones by sf-design.  Great shaders.

    Are they sold here at DAZ?

  • Serene NightSerene Night Posts: 17,571

    Those are the easy. Liquid ones mentioned earlier.

    How wavy the refraction is partially driven by how smooth the surface is... if  a pool is windless and smooth, you will seee very little distorted refraction; it seems to be trendy here in San Francisco to have fountains that look like blocks of frozen glass until you touch the surface and realize that it is a foot of clear water.  I would combine those shaders and a product like Sickleyield's water https://www.daz3d.com/rigged-water-iray-2.  i can never have enough

    Will's free shaders are HIGHLY underrated, IMO. I've not needed any other water shader since discovering his shaders. :)

     

       

    He also has quite a few other really helpful shaders.

    SY Pool Waters Iray (geometry and shaders); in fact, all of her water products fill a previously empty niche. Thanks @divamakeup for the heads up on Will's shaders. They look great, Will.

    I use Rigged Water Iray 2 (mentioned by Nemesis10 above) for most of my water scenes that need volumes of water. It comes with a good number of shaders, and I think it gets the under the surface effects right as well. It has 4 large scale water props that you can drop into a scene and scale accordingly - one round, two square, and one rectangular. I did this render, where I replaced the flat plane water in the pool deck with a rectangular volume and applied a shader that looked pool-water-like to me.

    Thanks!

    Procedural shaders have strengths and weaknesses. The big strength is the ability to have details that look good close up and far away without resolution issues or obvious tiling. Also no texture map memory.

    The big weakness is that the details are a bit more bland/simplistic than mapped images.

    I ever use an own setting with transmission. Scattering is optional, cause it extends render time extremely.
    If you choose Will's "Wavy Green Sea" you may alter following parameters:

    • "Scattering Color": (245,255,255)
    • "Transmitted Measurement Distance": 50
    • "Scattering Measurement Distance": 20

    Except the still persistent iRay Refraction Bug it gives a good pool water. Which looks pretty similar to my own setting.
    (Just a short screen render)

    Could someone supply a link to Will's water shaders.

    I have searched sharecg with no results.

    Thanks.

    Thanks much.

    They're spread out across several uploads. I recommend downloading them all from here: http://www.sharecg.com/pf/full_uploads.php?pf_user_name=wtimmins

    Like several people mention here, I really like Sickleyield's products. In the render below, I used SY Pool Waters Iray.

  • Oso3DOso3D Posts: 14,914

    I recommend:

    It's complete, you don't have to download the earlier ones. 

    I also have a few other things there that might be fun to play with.
