Problems running first Ocean test in Phoenix 2.0 and 3dsMax 2014

[lzmihich]

Gosh ! It's the most important 3dsMax 2014 and overall improvement in simulating Seawater,
without leaving Max interface.
Better than expected, and Genius work.Congratulations to the whole team !
I am amazed with the new Ocean tools for Phoenix.
Based on the example files I was able to simulate my first test.

For me, in this simulation, The problem is the "platform" that the PF simulator creates in the water.
I also don't know How to control the amount of particles efectively also.
I get confused with scale issues.
And I can see Vray Physical camera clips the ocean completely depending on the distance,
and is there anyway to have control of the Ocean's side, as it boreder's keep showing in the renders ?
I think I detected a bug , everytime that I hit the stop button in order to stop a simulation,
Vray opens and starts to render a frame, it's annoying.
I am using the Escape button, that is the workaround.
Greetings.

your sea looks great, better than anything i reached until now!
of course except the border of the simulator, which is visible.
in my observations, there are three general reasons for visible border
- the simulation waves reach the border, there is a fade out but if the waves are big enough the border becomes visible
- the fill up parameter and the ocean level of the mesher are not always exactly the same. the fill up sometimes needs few frames to reach stable surface, and it may be not exactly the numeric value set in the UI. you may need to adjust the ocean's level in order to hide the border. the best way to do this is to remove the displacement because then the border is better visible.
- low grid resolution.
i suppose your case is the second one

about the particle control: i would recommend to adjust the splash using its birth rate,and to produce foam using the foam on hit option. don't use direct foam birth, i.e. set the foam birth rate to zero.

about the camera clipping: yes, this is still an issue. actually the problem is in the mesher, not in the camera. the mesher first builds a flat ocean surface that is about 20% bigger than the viewing area, and then displaces it, but the displacement may drive the end parts of the surface into the viewing frustum. unfortunately the only way to remove such artifacts is to play randomly with the texture seed, or to clip the bad areas.

Not true , I think the Submarine and the River vídeos are awesome.
and I tweaked fom the submarine setings started creating a preset , etc...
If it looks any good it is because Phoenix Ocean is amazing.
in other words, it looks good because your submarine video does !
I really think is fantastic How the foam and splashes are created with such realism in no time.
and I wish I would know more Vray than I do, still learning.
I also think it is the second case , my resolution is reasonably high (16000)
I'll make the waves smaller anyway, if you see the video on a loop mode you almost get sick.
I'll twak and randomize the Phoenix Ocean texture , or clip the hole areas as suggested.
Thank you so much, and best wishes , Phoenix 2 update brought Great News.!!!

i meant your sea surface is better, not the entire simulation. you have not this annoying white skyline like in the submarine sample, i think it's just good environment map.

I also think it is the second case , my resolution is reasonably high (16000)

16000 what? if this is cells, it's very low, the submarine has about 17M cells.

Yes, I agree, actually the simulation is flawed, I am still clueless.
What I meant is that anyone will achieve great looks using those tools.
proper Shaders in Vray can make it shine,whatch for few great HD Ocean clips from many users , soon,
all over You Tube and Vimeo.
as you maybe have guessed, I used an HDR file as environment, but I made it Lowres in Photoshop.
Sorry , I made a mistake the resolution is not 16000 but exactly 8 542 856.
Still lower resolution ,but I made it like that only to simulate faster.
Now, In order to avoid the artifacts.
I'll try a higher resolution .
17M like the Submarine maybe, and a bigger colision object,of course.
Thank you for the help, I am sleepy, It is very late in my Timezone.
...After a good night of sleep , eventually got a better simulation result, sorry the shader isn't fancy as before !
it is on the images post below :

Hi, this is because the "Use Script" option is active, and in the script, there is a "max quick render" command on OnSimulationEnd()

Thank you, I'll verify.
