Spotty Fluid Emission

[ptb]

Hi,

I just dont get to the bottom of this problem:

It's an animated loft object that should create a thick & full emission, but its spotty - what can i do?

I'd appreciate quick help very much (deadline ahead)

thanks in advance

it is not a resolution problem ?

or just a hardware error, does it render the same ?

cheers
