Fluid velocity field

#1

Hello,

I made a 2D container with static velocity field.
I want my particles to follow the stream. I did set affect objects (fluid/particles)

My particles don’t seem to follow the painted velocity field.

thanks,

Make sure the fluid is applied as a field to the particles in the dynamic relationship editor. On the particles make conserve = 0 so they exactly follow the flow. Also make sure the fluid sizeZ is large enough that the particles are inside the fluid thickness.

While we are on this topic, is there a way to modify the magnitude of the fluid velocity on the particles? Setting conserve to 0 will disable the possibility to use other fields together with a fluid field.

Thanks Duncan

Now I want to use a 3D Fluid container with static velocity grid, to drive my ocean spray particles.
I used the creation expression from the Maya Fluids DVD, but I want to surf my spray particles with a fluid velocity field.
This is what I have:
I made 2 oceanshaders with a little time difference to calculate the velocity.
How can I put this vertical ocean velocity onto the particle spray?..

thanks,

bern
