Scope of nightlies/phoenix in general

[Steve_Green]

Hi,

I've been looking at the some of the Houdini lava examples recently, and trying to replicate certain bits in Phoenix.

From what I can work out, viscosity is (currently) a global setting in Phoenix, isn't it? (It can be animated but only over the whole system, not locally)

Is this the sort of thing that could be added with the current system, or is it a whole new thing?


Same applies to temperature for liquids - Phoenix flags a warning if liquids have a temperature above 1.

I'm just wondereing what the scope of Phoenix is in general (not a complaint - the new FLIP solver is great, just curious)

Thanks,

Steve

yes, the viscosity is globally controlled, we have still no mapping. of course we will add mapping, but not now, because it's not a work for one day.
about the temperature - phoenix was intended to be a fire/smoke simulator, and in the beginning the liquids were just cold gases with some additional magics to keep the surface sharp. that's why the liquids are exported in the temperature channel and have no temperature itself. using the flip solver there is no reason to be exported in the temperature channel, but for compatibility reason we kept the old pipeline alive.

OK, thanks - looking forward to seeing where it goes!
