This is because SSS component is not within BSDF, but in the emission (Ce). You can see that your BSDFs did mix properly, but SSS is still added on top.
You have to subtract it by the same amount you mix. Multiply your Ce, or if you are using Surface Model (as I'm guessing) it might be convinient for you to plug your mask into SSS Intensity.
Care to help finding those threads? Or any advice is good too. Really wondering if there's something else to this than Volume quality and Transparent samples. Thank you.
Hi! I found this thing to be very interesting for someone looking for car crashes. I think it's some sort of FEM too. Too bad we can't have geometry caches from this thing, because quality and stability is really not bad, also considering this is real-time.

There was a thread on this not long ago, maybe it's worth to try searching. If I remember right it was about not having enough pressure to push new liquid, maybe you have to add some divergence with your source? Also maybe reseeding could be involved too?
As a small tip I would suggest for you to check Add ID on the solver node, if you go the way Dan is describing. That will enable you to randomize bubble size without flickering (based on this id attribute rather the ptnum).
I'm not sure if this is accurate comparsion, given that Envy model is 2010 with both CPU and GPU being AMD (and MBP is 2012 Intel model). I meant something more like that http://amzn.to/1l2ADoC, but with 16 GBs.
Hi newbee,
I can recommend from personal experience HP laptops of Envy dv6 series (or Pavilion depending on your country). For ~1000 dollars you get a 16Gb / i7 beast ready to sim and render 24/7 Seriously, I pulled the heck out of this thing and had no problems whatsoever. In my opinion, greatest price/value deal for Houdini stuff.
Thanks, ikarus! It works really well. Render time seem reasonable too, for this image it was 0:08 / 0:22 at 8 steps, of course low-res, so probably not the best example to test. Technique is very cool, thanks again, so much abilities there.
