               Two ways from what I can see

Some emitters will have that action when they hit the ground, but I have the feeling you'd need to scale it pretty huge in the decay states which may not work for what you want. I thiiiink the standard water elemental is like this? I know I've seen critters who leave drops of stuff on the ground

In the other case, just an emitter that scales large as it decays set at foot height would do the trick

Copy that one and tweak it to your needs?

 


That's how I've always worked with emitters.

Warcraft emitter from the Water Revenant, not a NWN one

this is how much I play warcraft, Six. I can recognise the emitters on sight.

Mind the systems use similar values in the emitter fields, plus I'm 90% sure that its a combination of two emitters and not one

Heh, well... One can always just borrow a similar emitter from elsewhere. And it's two emitters alright anyway. The waterfalls in my Wild Woods I know have a very similar effect. Off the top of my head I think the waterfall tile that randomly shows up somewhere in the vanilla cave tileset has a similar effect too.

Not only is that two different emitters (the downward flowing particles with bounce, I believe, and the flat ring billboard), but the bottom emitter, the ring billboard, also has a sprite atlas for animating the flow.


 


Right off the bat (I.e. being too lazy to actually set up the project and experiment), I can see three ways to do this (ignoring the partical emitter, which I assume you'll just grab from the water elemental):


1) An infinite lifetime billboard emitter with an animated sprite atlas of ever expanding rings.


2) Ephemeral billboards of expanding scale using the default ring tga


3) A combination of an animated ring sprite atlas (for a more liquid feel) and ephemeral upscaling billboards for the size.

Are you sure it's animated? I reckon it's just a static ring and the particle mesh itself scales up - which is perfectly possible with NWN emitters.


 


Incidentally, Rolo, I just noticed how I can't help but leave your ending tag in after quoting only part of your post. Guess I think it's invalid syntax if I don't.

<mangling syntax...>


 


Been a while since I played Warcraft, and never played WoW, but if that's the model I think it is, the actual graphics are animated on the billboard.


 


But billboard emitters are pretty cheap for something like this, which is why I suggest doing both. :-)


 


And, yeah, although my op-end syntax was originally developed on fido-net to make it harder to counterfeit my posts, it really does help identify me here, doesn't it? ;-)
