Thanks! Mmm this tutorial is a bit dated as I wouldnt use fluidfx at this point but nexus fluids (sph) with granular mode on. Do you know how to do that? Let me know if you need help! cheers

Hi Thanos. It's so nice tips. thanks. I have a quick question. There is a problem that the particles keep going up as soon as the X-particle fluid fx effect is applied. I set it up the same as you, but I don't know what's wrong with it.

U define the size as "Random" from xp (extended data) in case i didnt show it in the video, and octane tag understands it.

Nikhil Shahapurkar

Hey Thanos. I have a question. How are the cube sizes getting randomized, since all cubes are of same size. The Octane object randomizes or the Forester plugin does it? I don't have Forester plugin so would not know. Thanks.

RF is a shitty plugin honestly haha. Very bad support while the algorithm is pretty good actually but they dont care. I doubt they still update it other than versioning. Cant wait for xp GPU (this month probably?) to see if its a better solution. Krakatoa is all about rendering doesnt contribute in other ways and its mostly for sand stuff where u need to multiply to millions of small particles. It' s not renderable in octane, it has its own render engine.

Looking back at this tutorial you mention the issue you had with realflow and getting it to handle a mesh or particle objects even though it had a better simulation. I'm thinking you could use Krakatoa in cinema4D to render the particles. I've seen a video of snow done with realflow rendered with krakatoa in cinema4d and it looked good. Just a thought.

hey hey! mmm not sure how that looks, but be sure to have the same settings (check also scene file). Imo my sand seems watery as well haha. I think xp struggle big time with their solvers for now. My problem in the video is the stability as u see particles are jittering on the ground and this is not something that should happen when set to hexagonal mode and definitely not with this small amount of particles. I may suggest to increase ur friction and maybe introduce a drag modifier as well. Again this comes to a lot of trial and error as u probably aware and with xp this take quite some time :)

thanks for that wonderful tutorial I am facing one issue after all the sim I've made when my object is rising from the sand it's not given me an actually sand kind feel its more like a watery surface waviness happening after the object passes through it how I can get rid of that watery surface feel and get some sand feel. thanks

ty bud!!

Really nice tips about using small cubes as particles! Great tutorial, thanks! :D

Thanos Kagkalos

check out the project file i dont remember by heart :) but usually i go for eg. if a cube is 1 i ll go by +/- 1 as well. the full variation is really important to breakup the pattern! If octane allowed also group distribution this would be even better i ll explain this at another time

Shannon Wilkerson

I was just wondering how different the size variations are of the cubes you used for the sand? And how large is the largest cube? Just wondering.

Thanos Kagkalos

Hi please check the project files :)

I can't increase live particles. please tech me

Amazing as always. But Once I Add xpFluidFX suddenly simulation is starting to force upword any solution ?

Lukasz Pason

Your patreon is always so loaded with tips. Thanks man!

Thanos Kagkalos

Hello, it shouldnt move if u let it rest. In my example I just dont :) I immediately start to simulate.

Adrien Dezalay

Hi Thanos! Very nice settings, I finally figured out what i was doing wrong this whole time. I was wondering: would you think of a way to keep the sand from moving all the time when it's not supposed to be affected by the sim? Like on the edges. Maybe a drag modifier?
