  1. Hi all, Relative noobie here, looking for general advice on how I might approach modeling a cancer cell that looks like this: https://www.mskcc.org/sites/default/files/styles/width_800/public/node/167374/3x2/sciencesource_ss21694540_1200x800.jpg [www.mskcc.org] or this: https://static.independent.co.uk/s3fs-public/thumbnails/image/2016/02/15/21/1-t-cell-corbis.jpg?w968h681 [static.independent.co.uk] One physical feature of the cell that I’d like to pull off convincingly is the sticky-looking tendrils that shoot out from the membrane, that look a bit like viscous liquid has been shot out from the surface of the cell. Though something like the image in the above links would be ideal, I would settle for something like this: https://lymphomanewstoday.com/wp-content/uploads/2018/09/shutterstock_565670083_zps0eglo9ri-1000x480.jpg [lymphomanewstoday.com] I would want to avoid something like this (where the tendrils resemble veins, or maybe octopus tentacles: https://www.segnidalcielo.it/wp-content/uploads/2017/08/GoldNanoparticles.jpg [www.segnidalcielo.it] Since for now I only actually need a static model, my first inclination would be to start with a simple POP setup, have some particles explode off a spherical surface and append a trail SOP to get the tendril trails. I’d run the sim and use a single frame from it as the cancer cells base geo. This only gets me so far though, as there are other important visual details that I’ll refrain from talking about until I some experienced person can tell me that this is definitely the way to go. My other inclination, which I realize might be inviting insanity, is to create a “fluid explosion”, using a FLIP setup with some velocity noise coming from the SOP level, and playing with DOP node settings to get the right kind of viscous/stringy effect from the particles. From there, again, I’d run the sim and use a single frame of geo for the base for my model. I’ve so far made an attempt at this (file attached), though have only tried seeing what I could get by using nothing but some noised-up velocity on the SOP source, some DOP gravity and tweaking settings in DOP Source Volume and Solver nodes, pertaining particularly to viscosity and surface tension (though I’m not sure the latter is relevant). I’m able to get some neat looking effects, but not really the ones I’m specifically after. What I’d wonder here is whether this ‘explosion of viscous fluid with a very high tensile strength’ could even be achieved with a fluid sim, and if so, would I need to push/pull the “sticky/stringy” fluid outward by having the FLIP particles stick to a set of “collision” particles which are then launched outward, pulling some of the fluid along with it. Or, could this effect be achieved by simply applying velocity to a Fluid Source SOP with very low particle separation, and then relying on settings available in DOPs nodes to get the long / stretchy tendrils. In any event, I’m certainly open to suggestions even if they’re completely different approaches to what I’ve described above. Thanks ahead of time to anyone responding!

  2. Greeting to everyone, So basically I'm trying to achieve the same wireframe as diatom star. And afterwards, bake it with my main model in one piece. It's should be sort of Voronoi pattern but a bit more organic and smooth. Search through the Google. Find a bunch of videos where people achieve the exact same pattern. Unfortunately, there is no explanation about how they get it. I'm a newbie in Houdini so don't judge me for my explanation. I will attach main model and some other additional files. Number 10 looks like what I'm looking for. Main Model.hip Main Shape.obj
  3. Hello everybody, What would be the best way to approach the effect like the reference images? I would like to have some sort of control to blend solid parts and drilled parts like in the second image.

    Hey guys, I worked on the simulations for this spot, it was my first serious houdini project, hope you like it
  5. Sup people, Just saw a video by Erik Fergusson (he got awesome houdini organic stuff) and I wonder how can I model something like this in Houdini, I'm always trying to figure out how to do abstract/organic stuff and I really liked this video. So my thinking (my knowledge of houdini is pretty basic): - This was animated throug FEM? looks like. The organic stuff itself: - some cilinders, duplicate, scatter some points, big dots over the cilinder for the big mass, and the small dots throug a copy sop? with stamp for randomness? if so, the scene would be pretty heavy right? - or can this be achieved through mantra materials? what I really like is the randomness on sizes and the colour palette, colour through attribute random maybe? - or maybe particles over the big form? Any input on how to get this type of form will be helpful, I could get a similar model with zbrush or cinema 4d, but since I'm learning Houdini and its becoming my main app (the more I learn the less I want to go back to other apps), I think would be a nice challenge to do this in Houdini, plus the future is procedural Thanks!
  6. FEM object to stay rigid

    How do i make a FEM object stay in air like its static but also take a punch and deform like its (Rigid) affected to gravity.
