Hi,

I know it's a simple thing, but I just couldn't figure out how to make water mater which would pass emitters and sunlight through and their secondary reflections..
Here is what I'm talking about: https://www.dropbox.com/s/a3mtazip54dilz1/11.jpg?dl=0

Any help would be greatly appreciated!

Thank you!

nobody, really?! Come on guys!

Hi can you share your scene ?
and where is the problem ? i tried create pool without problem

Hi Seghier,

Thanks for your reply, can you see this link (it's a drop box) https://www.dropbox.com/s/a3mtazip54dilz1/11.jpg?dl=0 ?

I don't know how to insert an image in here...

Hope it'll work!

[seghier]

use this website to upload your images
http://imgbox.com/
the image is too small

[seghier]

if you render the image with sky disabled the water reflect the color of the environment
so you will see black water
what you want get from this scene ?
emitter

sky

sun

Thanks a lot for you time, Seghier. I really appreciate that!

So here are my problems (hope pics will be visible this time). I'm using water as a solid box, maybe that's the problem..

Everything looks fine with the day light


I clearly have problems with sun...


And same problems with emitters..

[seghier]

hi ; thank you
i don't think that solid give good result
in maxwell studio the sea is big mesh not a solid
is your water intersect with the tiles ? can you show section ?

[seghier]

and try to make comparaison between box and plane with the same settings

[audrius01]

yes, my water is a solid box and it fully intersects with ground (tiles). And here I'm not using sea extension or displacement.
according to the law of physics it should work..

here is the rhino scene:


here is my water material. It's from default maxwell material wizard

[seghier]

according in law of physics it don't work because the water must not intersect with ground like that
in reality water in a pool for example or sea intersect witj the same faces
; but in studio the faces duplicated give wrong result
try with little distance between water and the pool . than try with plane only than with maxwell sea
and make comparaison

[audrius01]

okay, so it's because of the material.
I did some tests and as you can see the geometry doesn't matter, in both cases (solid and plane) the result is the same. What does make a difference is the material. I've downloaded glass which lets shadows through and it gives me close to what i need.

Here is a single plane. As you can see sun still can't get through it


Same plane with an emitter light, still nothing...


Plane with sky only-looks good, just like the solid did.


And here is what I need, here I'm using glass applied to the solid which fully intersects tiles. As you can see, both emitter and sunlight goes through.

[seghier]

for the water you don't need glass material
here tests with comparaison but i don't understand what you want ?
sky

sun

light

[audrius01]

Thanks Seghier.

I want water to look much more transparent under the sunlight and emitters.
I just don't get why under sky light water looks so clear (just like a normal water) and under the sunlight and emitters it becomes so dark?
In your examples too, it just looks wrong!

That's how water looks like under the sun, crystal clear


It's big difference compare to this, don't you think so???

[seghier]

but you can't compare this real phoro with this render test
in the photo you can use hdri ; sky ; sun to get better result with good material for the pool and with lights under water
you can not get this real result with light only
