caskal Posted January 7 Share Posted January 7 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! Quote Link to comment Share on other sites More sharing options...

hannes603 Posted January 8 Share Posted January 8 i would guess. flip sim + dynamic viscosity attrib amd a crisp displacement for the dry parts. 1 Quote Link to comment Share on other sites More sharing options...
caskal Posted January 11 Author Share Posted January 11 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! Quote Link to comment Share on other sites More sharing options...
hannes603 Posted January 16 Share Posted January 16 lava2.mp4 i did a little test with viscosity and displacement (material vops).. not quiet there jet. but still Quote Link to comment Share on other sites More sharing options...
crispr_boi Posted January 31 Share Posted January 31 I know this only visually related, but maybe it can still help? Membrane tearing - OdForce And I was also reminded of this, though I have no idea how one might combine it with FLIP.. Entagma - Quick Sand But most likely it is just the emergent patterns that arise from setting up the sim with true to life properties - the interplay of the outside cooling down with the hot inside expanding and linking it to viscosity - therefore imitating nature? I would love to be able to create this <3 Quote Link to comment Share on other sites More sharing options...
