My goal that im trying to achieve is to melt ice cream with a flip sim using viscosity and have it be driven by attributes over the period of Sim. i fairly new. but i have managed to get the *ice-cream ball to only activate when the object passes by the ice-cream. I have a few main issues.

for reference this is the kind of melting im looking to achieve




1. i have figured out how to color the point volume of said icream and group it into points i want to be activated and ones that i don't and also to vary the level of viscosity (problem) it does not seem to read it in in the dop sim.
2 another main issue i have is that ice cream melts in 2 ways.. The overall form then also the melt happening from the outside in where it is a runoff and it loses mass form the outside in.

i have been racking my brains and went to this link in the OD forum from 2014 and it kind of is exactly what im looking for but at the same time not. id love to see it done with a full houdini 18 node setup. as mixing it with nodes from 2014 makes it trick for a newbie like I. Also id love for this to become relevant again as the discourse for this kind of setup which albeit simplistic is incredibly complicated and not wideley discussed on the forums..

anyone willing to help id be forever grateful

Here is the file im working on
@eetu where are you haha!
