Powerful water push an object already animation

[HoanCG]

How can I make the water simulation like this:

On 1m:57s .. Very strong water push her fall.. I need white water and want to make it like that.. I generated so much foam particles and tried render it with point mode, motion blur.. but look not good and V-Ray render very slow.. anybody can help me make one tutorial for this case? Or lead me how to make whitewater? Whitewater just make from foam? Please...

Hey,

It's always better to help out finish the setup you already started instead of starting from scratch - can you share all your Phoenix and V-Ray settings and a video of how the simulation looks right now?

Thanks!

This's 3 picture with whole my setting.. with V-Ray, I just play around Progressive and Bucket mode for batch render..
In this scene, I afair too much chaotic movement because this scene too close with camera, s o I decrease the value of foam and splash, just use Mist with Fog mode..

Hey,

You have very, very few particles - 10'000 particles are way too few. Usually you would need several million particles to get a good look.

How long are your render times? How many lights do you have in the scene and what kinds are they? Do you have any HDRI lighting?

Can you also share the Particle Shader settings? You render the particle through the Particle Shader, so the important option regarding speed and quality of rendering are there.

Cheers!

As I generated too much particles, my scene has so much noise (camera so close with my water) .. before, I generated about 8 millions particles, just for foam created from splash..
I have 3 vray light plane, and 1 IES light.. havent HDRI because my scene in close room.. I took 1hr for 1 frame, and my scene have 43 frames..
I just want make a huge powerful water push him guy fall.. usually the water should be have very brightness color..
I will upload some picture about my particles shader below.. thanks because quick reply

I found someone make whitewater like volume, motion blur unnecessary.. Must I convert mist from splash more than or render foam with fog mode? ..

Hey,

Try to change Force On of the motion blur to From Renderer if you don't really need to have it forced.

Also, try increasing the For Voxel Size to 5 or 10 and see if this helps render times without making the fog too low res.

Cheers!
