Quick Question about water

[Anonymous]

If you rendering swimming pool water in Revit 2017 (not on the cloud) does it look like the first picture or the second?

I can readily see from the shadows in the two jpgs that the rendering settings are not the same. What other rendering settings are not the same? Yes, 2017 uses a different rendering engine, but it doesn't effect output as radically as shown here. I still believe an explanation lies elsewhere.

"clearly"   I see what you did there 😉

To answer your question, maybe their check bounced so that Mental Ray or VRay terminated their license ¯\_(ツ)_/¯

Autodesk used to have an in-depth partnership with NVidia which gave them excellent access to Mental Ray.  However that also retarded the development as new features were dependent on Autodesk development.  Recently there was an "amicable divorce" between the two developers which allowed for a few beneficial future developments.  One was making it easier to include various different rendering engines in Autodesk products; the other was allowing MR developments to be made without having to wait for Autodesk product advancement.

This part is pure speculation... Making it easier to use other renderers also makes it easier to add the newly acquired Arnold engine from Solid Edge.  I wouldn't be surprised to see it as a rendering option in multiple products (outside of 3DSMAX and Maya) in the future.

Thanks guys: I did miss the part where Robert stated he was comparing renderings done with different engines. So, obviously, they don’t share the same rendering settings. But still, 2017 is perfectly capable of rendering photo-realistic swimming pool water, as evidenced here:

yes!  thanks for doing creating that sample! 

the water appears to look fine when its shallow and a just small portion

okay, so that's great, I believe, we can now eliminate the rendering engine as the problem.

and perhaps focus back on the operator as the source, um me!

okay, so I also conducted an experiment with shallow water as seen on right of pic, water extrusion on right and

another rectangle extrusion on left and it appears that shadowing might be the culprit as it looks muddy because of the top of spa shadow

if I could only eliminate or fade out those dang shadows a bit or make the water more transparent?

I think you're on to something Bradley, as it appears the rendering issue may not be the issue and in fact maybe your mention regarding shading.

Because the water comes out fine when the depth is very shallow and only a small area to render.

see the pic with my water extrusion on the left that doesn't have the spa shadow hitting which appears to render better than the rectangle extrusion on the left which is receiving the spa wall shadow.

do you know a way to make the water more transparent and or fade out the water shadows a bit?

actually, I am starting to think It might be a rendering issue again.

pic 1 rendered in 2016

pic 2 upgraded the model to 2017, no other changes, rendered and now get that mess on the left

its now dark and muddy

Did you set the render quality to Best?  My primitive understanding of Raytracing engine is that the more passes you let it run, the more light bounces you get, and that may help with materials such as water, especially when it is deep.  Or try one with just a surface, not a volume.

[barthbradley]

LMAO! Yes, “depth” is one of many factors that affect rendering appearance. That’s exactly what I was explaining to you in an earlier post. However, in my rendering above, the water has NO DEPTH.  Seriously; I kid you not.  It’s a painted surface.

okay, so here I am again logged in as someone else but I am also rmdinelli

I am so surprised that nobody could answer my question bellows because all I had to do was render to the cloud and my water problem was fixed instantly.  With all of the responses I had none of that offered that quick and easy solution. 

Problem solved, just render to the cloud!

all I had to do was render in the cloud and now my water looks great!
