Scale a fluid system with an object emitter?

[puppetsoul]

I want to use the fluid fire exemple, this one with the torus who burn.
I replace the torus with a wood piece.

But when I want to scale (x30) the effect to the size of my scene, the effect is completly different.
I have try to scale some world scpace attributes, but it doesnt work.

Some body have a proper solution to scale this effect?

thanks in advance...

I have the same problem too.

Anybody can help, please

On the emitter adjust:
Density/Voxel/Sec
Heat/Voxel/Sec
FluidDropoff

Divide each of these by the amount you scaled by. Note that if your object has a large scale then the dropoff does not need to be modified, however if one does freeze transforms on your object, then the fluidDropoff needs to be lowered (the dropoff is in "object space", or relative to the transform's scale of the object).

I've had this problem in the past, and have solved it but scaling everything in the scene down. (if you have motion curves don't select/scale them)
I tried what you said Duncan, just as a test. and I'm not getting perfect results...

Imported the TurbulentFlame scaling by 30...

select -r Flame ;
setAttr "FlameShape.dimensionsW" 300;
setAttr "FlameShape.dimensionsH" 300;
setAttr "FlameShape.dimensionsD" 300;
select -r nurbsTorus1 ;
setAttr "nurbsTorus1.scaleX" 30;
setAttr "nurbsTorus1.scaleY" 30;
setAttr "nurbsTorus1.scaleZ" 30;
setAttr "nurbsTorus1.translateY" -60;

"Divide each of these by the amount you scaled by. "

select -r fluidEmitter2 ;
setAttr "fluidEmitter2.fluidDensityEmission" 0.033;
setAttr "fluidEmitter2.fluidHeatEmission" 0.066;
setAttr "fluidEmitter2.fluidDropoff" 0.066;

What am I doing wrong I've also tried...

setAttr "fluidEmitter2.fluidDensityEmission" 30;
setAttr "fluidEmitter2.fluidHeatEmission" 60;
setAttr "fluidEmitter2.fluidDropoff" 60;

and...

makeIdentity -apply true -t 1 -r 1 -s 1 -n 0;
setAttr "fluidEmitter2.fluidDensityEmission" 30;
setAttr "fluidEmitter2.fluidHeatEmission" 60;
setAttr "fluidEmitter2.fluidDropoff" 2;

And more variations of the above. Again, in the past just scaled everything down, if I wanted to use a imported fluid, but I'm still unclear as to how to get the scales all working properly. And how the container scale/emission technically relate.

you posted this that helped on the relation of scale within/out side the container.

Thanks for your time in helping us Duncan!
