Why there is no foam in the bow of the ship?

[georgi.zhekov]

Looks like the geometry of the ship is open somewhere. You should work only with closed geometry. If it's closed you can try and turn on the Clear inside option.

Right-Click on the object and from the PhoenixFD menu choose Clear Inside.

artmaestro, I think you have mistake in your settings...
RTFM please

how to form a foam in the bow? and how to decrease in the selected part the foam's grain?

[georgi.zhekov]

You can try and decrease the velocity threshold for the foam.

For the grain you need to increase your max vray samples for the rendering and lower your noise threshold. You can reduce the size of the foam particles as well.

with reduction of speed limit the program shows ...(32GB memory)
how to reduce noise threshold in vray 3.4?

I reduced the size of foam to 0,005

[georgi.zhekov]

You need to try and find a threshold that is high enough to generate foam but not much to run out of memory.

In VRay tab under the Image Sampler - you can increase your max samples and change the Noise Threshold.

[artmaestro2]

vel threshold 25 = 20
max subdiv 4 = 6
noise threshould was 0.001

[flipbook]

noise threshold of 0.001 is overkill in 3.4 Even the usual 0.005 can be too much.

[artmaestro2]

foam amount =0
Vel. Threshold =1
size of foam =0.005
particle system(size limit) =0.001

[artmaestro2]

sorry, particle system(size limit) =0.01

how to make foam grain is smaller and the number of more?

[georgi.zhekov]

If your foam amount is 0 those thing in the picture are splashes.

You can increase their count by adjusting the amount multiplier as for the grain, increase your VRay max samples - you are using 6. Try with 12 or even 24. Some scenes require even more.
