dasqub20 Posted February 24, 2023 Share Posted February 24, 2023 Hi all, first time posting Was wondering if anyone has any suggestions on how to achieve an effect of water being absorbed by a rock/surface. this is the reference I was given: https://www.youtube.com/watch?v=7ri-7xaZfjk&ab_channel=ThisIsHappening My first idea was doing a simple FLIP sim of a drop falling to get something to work with, then creating 5 pts as goals/absorption pts, and then interpolating the flip pts by the position of those goal pts by nearpoint. The main idea is just to create (maybe) a mask that defines how strong those pts pull the liquid and then eventually make the liquid disappear. I did a previous test using "suction force" but I don't think is what I'm after. I'm not sure either if it's better to achieve it during sim time or post-sim?? Any ideas? Thank you Quote Link to comment Share on other sites More sharing options...
Benyee Posted March 1, 2023 Share Posted March 1, 2023 This simple example is just for some tips. Try deleting the particles contacted with colliders in a sopsolver, "contacted" can be judged by distance between particle and collider surface, or by some other approaches. And I think you should make some wet map stuff for the absorbtion effect as well. liquid_absorbtion.hip 1 Quote Link to comment Share on other sites More sharing options...
dasqub20 Posted March 1, 2023 Author Share Posted March 1, 2023 (edited) Thank you so much Benyee for taking the time to reply and for the hip file. Really appreciate that!!! I completely forgot that I could remove points by collision. I think I went down a much more complicated path than I should have haha. This is what I ended up doing for this one. I created a mask based on position and added some noise so we can have some nice patches and then transfer to the moving pts by id. Then, on a wrangle what I did is find the nearpoint from the collision obj and interpolate position using that noisy mask I created before, sure we still get the particles on the collision surface so I´m deleting those by distance. Adding some screenshots just to be more visual I am not the best at solving problems or writing code, sooo any comments are welcome. Thxs again Edited March 1, 2023 by dasqub20 Quote Link to comment Share on other sites More sharing options...
