  1. Creating waves with vertical lines

    Hi, I have a question about the ocean spectrum node. I have created a deformed wave using a grid with ocean spectrum and ocean evaluate node. I can change the ocean spectrum wind direction setting to achieve the kind of look I want, which is to have the vertical lines on the ocean surface, something like the image below. But if I only do that, the waves direction is still wrong, they are moving sideways. Is there a way where I can create this effect with chops moving in the right direction? I thought perhaps I should create another ocean spectrum and put it on top of the first ocean spectrum. This is pretty urgent, does anyone have any suggestions? Thanks!
  2. Blending 2 waves together

    Hi,I have used the attribute VOP to create 2 separates wave deformers. I would like to blend these 2 together to get the shape that I want. I tried using different attribute nodes but I can't achieve the effect of blending the meshes together. How do I go about doing it?I have attach my nodes network and the image here. You can clearly see that the meshes are separate, I want to combine the mesh. I tried joining the 2 attribute VOPs one after the other but that only increases its amplitude and nothing else, I want the 2 mesh to join at different position so I get a v shape effect like the png image I show here. I thought of perhaps multiplying the 2 wave matrix together by using the attribute wrangle node but i'm not sure how to call out the VOP variables individually when both waves' output is the same (position P). Is there a better way to do this? Any help and advice would be appreciated, Thanks!Eunice
  3. Hello guys, I'm working on a Bifrost liquid mesh that I imported into Houdini to render it with mantra since Maya couldnt manage my huge alembic file ( +300Gb ). There is no foam yet since it's in the process of meshing but I wanted to know what do you think about the liquid mesh shader ? I used the Ocean material from Houdini with some adjustment. Thank you guys!
  4. Hey guys!!! I’m playing with a large ocean render using Mantra PBR. In my scene i have a simple HDR environment light, and an Area light. The Area light is actually creating all the specular highlights in this render and shader is the default from ocean waves. I’m not sure what passes to render for composite.. Right now i’m rendering depth pass, normal pass and directreflection pass. I would really like to have the specular in a pass, and maybe some kind of motion vector pass, how do i achive this? Since i'm using the defualt shader, i'm guessing i just have to use the correct vex variables for output extra image planes? If that makes any sense.. And can you houdini experts perhaps recommend me some other passes to render for oceans and flip fluids? Any help is greatly appreciated, thanks!
  5. Strongly based on (mighty) Igor Zanic old Naiad test of an helicopter, I worked on this test to get the hang of the new Ocean FX tools in Houdini, as well as testing how to use custom forces to affect FLIPs (to simulate the helicopter blades). Sorry for the somewhat grainy render and some Nuke retiming flicker around. I didn´t have the time to retime and re-render. I think I make up for this with an interesting test. My conclusion so far is that it´s very difficult to use dynamic waves and still keep your main effect strong and controllable because of the amount of interactions going on with the waves. The reason being dynamic waves require a really huge container not to come back too soon and this adds up on the usual problems on any similar scene.
  6. Flip fluid beach

    Hi everyone. With my first post I want to show you my recent personal project and thank all of you for creating this great community. The setup was pretty simple. I used off the shelf beach tank and separated particle generation from tweaked velocity advection to start with clean and plain sea body. The boat was simulated with low res version and then used just as collider for the final one. Main fluid contained about 10M particles and foam maximum of 1,7M per frame. Everything took about 10h to render on a single machine. Hope you like it. Thanks for watching!!!
  7. Hi everyone, I’m pretty new to Houdini, so please bear with me. I want to try making a little boat passing through a body of water. Now I know how to use the boat to affect the water and create the wake, but I also want the boat to be affected by the water: I’d like for the boat to rock with the water’s waves. Is it even possible for an RBD object to be affected by a flip simulation and if so how does it work? Or would I have to animate it myself? I’d be grateful for any help you can give me Thanks in advance! Cheers
  8. My deadline is very tight and client want big foamy waves like DNB bank TV Commercial. Which is the best way to get that kind of effect, Ocean shelf tool to simulate wave or wave tank shelf tool? If I use Ocean tool then how to get foam out of it? Pls check attached reference images from DNB Bank TVC. Foam Ref..zip
  9. Controlling Ocean Waves

    is there any way to control Ocean surface that it can generate waves only at its last part like we see in real ocean (overall calm but waves in the end)
