  1. Hi I made a 2 part video tutorial on FLIP Tank simulation and the other one is about how to render the simulation. They are both targeted for beginners level. The first video is titled, "FLIP Tank Basics for Beginners" and demonstrates how to setup a FLIP Tank sim and how to use the Waterline feature. I explain how to setup the FLIP Tank so you can actually see what's going on inside the container in the 3D viewport when you cook the dopnet before you render. The Waterline feature will allow you to simulate the fluid so that it passes through the boundaries of the container. The 2nd part of video tutorial is on how rendering and how to render out the FLIP tank scene from the first video. It's titled, "FLIP Simulation Render Setup in Houdini". This video is also targeted for a beginner level. I talk about the difference between DOP Import vs DOP I/O. And the concept of inputting data into the dopnet simulation and how we need to extract data out of the dopnet sim into another context for rendering. I'm still finding my style in teaching, if you have any comments please feel free to give me some feedback. And if you have a topic you want to see, feel free to post that in the comments as well. I might not get to it right away because it takes a lot of time to edit these videos, but it will come eventually. Thanks!
  2. I have a collision object that I want to push through a particle sim area. I want to remain the small sim area (box) so the particles stay inside the tight area but once it gets hit by the collision object the particles that were affected by the object fly off. How can I achieve this? Thank you, this is the file I am talking about. Particle Collision Tester v03.hip
  3. Hey guys, I've been trying to use the extrude polygons feature of the Particle Fluid Surface, but the bounding box makes my meshing weird, even tough my mesh looks fine without using the bounding box. Using the BBox, on the first four frames the mesh just goes away and I also get some gaps between the mesh from the flip and the mesh from the extended. Since I need the Bounding Box to extend my ocean using the Particle Fluid Surface node, and that's acting out, I'm looking for some good alternatives to that. Does anyone has any suggestions?
  4. Hey everyone need some help with my whirlpool simulation. I probably didnt do this the ideal way but i only have about three weeks experience so far in houdini at all so trying to go from knowing nothing right to a particle simulation was tough. I am working on a whirlpool simulation and i need about 10 seconds for the simulation. The main thing i need some help on is the particle separation, the voxel size and adding foam to it. Of course any other tips and tricks are appreciated as well. The houdini file and some screeenshots of what the current simulation looks like are attached. Thanks Guys! whirlpool_v024.hipnc
  5. WhirlPool Attempt

    Hey guys i was wondering if any of you could give me some guidance on a whirlpool simulation ive been working on. I can submit the file if anybody would like to look at it that would be awesome. I guess the main problem im having is determining how high of quality i need to make everything. For my project in school we are using maya and arnold. I have the Rop output nodes setup and i think i have a feel for how to convert it to an alembic and importing it to maya from there. Any tips that anyone can provide would be great. whirlpool_v021.hipnc
  6. Flip Tank to track objects?

    Hi, I am running a boat simulation with regular flip tank, i am trying to figure out how to track the flip tank to the boat... After some quick search it seems that i have to use a FLAT tank or a tank that came with ocean suite Is there a way to keep may flip tank and make it follow may boat? Thanx
  7. I have a very big river scene, it's a very simple scene with just a FLIP tank. I want my FLIP tank to generate some waves as time goes by, so I added the wind force right after my FLIP object node. But now I noticed a very big problem, as the frame hit aroud 130, the whole river starts to flicker. And it flickers crazily after frame 160... Can someone please help me? My deadline is coming really soon!! Arghhhhhhhhh!!!
