Lava question

[caskal]

Hi magicians,

 

I've been obsessed with Lava since I came from my trip to Hawaii. Been doing some R&D in Houdini for the last 3 weeks but I can't get closer to a video I saw and I'm getting crazy.

 

https://vimeo.com/293242455 on second 0:18 you can see how it expands while creating some noise on the cold part, like a spiderweb being ripped by the heat lava.

 

I read some comments that he uses pressure field, I tried using that to drive divergence for expansion or temperature but isn't working as expected.

 

Any ideas on how to get that? 

 

Been playing mosly with noises to drive temperature / viscosity as well as some microsolvers like gastemperature field, also tried having 2 emitters, one cold in the top and hotter in the bottom to drive the magma.

 

Cheers!

with Perfect files, you only need to tweak .

i would guess. flip sim + dynamic viscosity attrib amd a crisp displacement for the dry parts.

Hey guys! @Librarian thanks for those resources, I knew Gen Li but didnt know the other, will check it.

@hannes603 checking his comments he didnt used any displacement, crisp was done via some VOPs and surface, but thanks for the tip!

Cheers!

i did a little test with viscosity and displacement (material vops).. not quiet there jet. but still

Did you find a way?
