Mulitple Emitters In A Wake/foam Container

[thomasgraham]

I have a scene set up in Maya 7 with two ships along side of each other. Simple animation not a lot involved. I have a total of 4 emitters two for the bow of the ships, two for the stern. Bow emitters are emitting wake and foam attr. The stern is only emitting foam. These emitters were not copied from the original but added each one separately due to copy emitter bug existing in Maya.

I can only get one emitter to emit foam at a time. Other scenes, i had up to 4 emitters working (no wake, just foam). It seems that the last emitter to be linked in the dynamic linker is the only one that will work or only link one emitter.

Individually they work, but not together. So I assume that the settings on the emitters are fine.

I've created at total of 52 water animations and have come across this issue 30% of the time having to recreate the scene.

Is there something i am missing? I have a deadline fast approaching and a fix to this will be greatly appreciated.

hi,

normaly if the containers are not into eatch other it must work.
But if there is an interpenetration it probably will not work
maybe you can only have on container for wake and one for foam
i don't know.
Try to have only one and add a second wake emiter....
you know what i mean, 1 container for the foam with all your emiters into
and 1 container for the foam with all your emiters into

try this
Good luck

When you initially add a wake/foam to an ocean maya creates two seperate containers one for foam projection and one for a wake projection. An emitter is created that is dynamically referenced to both containers.

Just to make sure, what you are saying is create an emitter that is linked only to the wake container and then create another emitter for a foam container? I will try that.

Thank you.

still the same issues.

In As i let the simulation run, i can click each emitter in the Dynamic Relationships window and see watch one turn on and the other turn off even though both emitters are linked.

There was one time when i clicked a specific order and had three out of the four emitting but the bow of one ship seemed not to respond.

i think i may have figured it out...although with all the mixed reactions i get we'll see in other scenes if this works again.

I cleared initial state, deleted cache, and then trucated cache, and then unlinked and then linked one at a time and it seems to work.

Maybe there was an issue with too much info being stored and returned unstable results.

who knows...we'll see down the road...thank you for your help!

negative on that post above.

I opened an existing scene to add a small one engine boat. So i added a fluid emitter to the container (total three) did not emit into the container. The other existing 2 emitters worked fine. As soon as i unlike one emitter the new one will start emitting. i can only get two at a time in this scene.

I think there is a bug where you can't mix volume and surface emitters on the same fluid. Otherwise make sure the emitters are connected to the fluid using the dynamics relationship editor.
