water foam

Hi,
Can any one help me in creating foam for a water wakes, when a ship travelling in a sea.

First of all, the ocean should also be a RF object, a realwave. Then you would need to bring in the animated ship into RF, and turn that into a realwave object as well. If you're using RF4, it automatically turns your object into realwave and make it interact with the ocean.
Under the ocean's attribute, turn on Calculate Texture, and then "Fit Texture". That's gonna leave a white wake behind your object. Now, you might need to play with this texture's resolution, propagation, and ageing (a higher value will make it disappear faster), depending on the size of your ship.
Hope that helps.

hi,
Thank you for your kind reply.
It's working well.
Now will you please tell me, how i have to export these water foam from RealFlow?
Iam using 3dsmax8 for final rendering.

When you do an export of a realwave animation, it's going to be different from a regular bin file sequence. RF is going to output a single sd file (named as Realwave something), just like Maya or 3DS does. Just make sure that you check Realwave object for exporting. Import that file in your rendering app, and that's pretty much it.

Hi,
Thank you for your reply.
It's comming well.

One more query.

How to make natural looking water splashes.

I animated the ship in 3dsmax and exported it as .sd file for 0 to 100 frames. I imported it in realflow, then i applied rw_splashes and i selected ship as the object. Later on i applied gravity deamon.

But the splashes are getting emitted like a spray in the air. If i built mesh, it appeared like a bubbles. Please check the image that i attached(This image is final rendered in 3dsmax)

How to export these splashes from real flow(as a mesh or particle).

Will you please mail me, how to solve this problem.

The splashes should also get exported as a Realwave object. You can make them smaller in 3DS so that they don't look so big and blobby. But if that doesn't work out then I'd suggest attaching an emitter to the front of the ship in 3DS. It'll be easier to control particle splashes in your 3D app than in RealFlow. This way you can reduce the splash size according to the speed of the ship. It will also reduce the rendertime.
Hope that helps.
