veeeery good, congrats!!!
only the water over the bank sometimes makes artifacts, i suppose it's easy to cut this off
is it for production or just r&d?

Thanks Ivo!
This is just RnD, but yes, I also did mask off some other artifact spots in comp and also unwanted splash particles which where produced by FT in areas inside the ground object.
But I couldnt use cut gizmo cause I use static mesh option for the displacement of the water(PHX ocean texture).

One thing what I havet try yet is use wetting whit very very long drying time to preserve cells long enough on these problematic diagonal areas.

One other problem are the cells which accidently penetrates the car and preserved inside, and when the velocity is high enough, will release. Actually in shot like this it is not so bad cause more splashing water near the car just makes it look more interestig

There is an option to clear the cells inside the object. May help. It's in Maya, not sure if Max has it.

[Ivaylo Katev]

in max too, since few days

[TSR_trix]

Sounds great, how do I use this option, im using Maya?
This is very needed also in ship simulations (coming soon).

btw, seeing carefully the video, the light reflections in the water are longer toward the water movement, motion blur in post perhaps?

Select the object, add AE -> Attributes -> Phoenix FD -> Phoenix FD Object. This is exactly like the VRay extra attributes. Then look for "Clear Inside Solids". There are 2 options to clear. The first one is if the object itself is moving. The second one is if it's static and other objects are moving through it. This may leave some parts not updated, so this option is also forcing updates.

Do you mean those highlights in down stream? I have displacement to get fine detail over the stream, and a bit glossy in reflections, that maybe be it?
Motion blur is Vray camera MB.
For lighting vray sun and dome light HDRI.

[Ivaylo Katev]

yes, these highlights. perhaps is the glossy
