Hi guys, I want to simulate two (or more) boats in a large ocean, so I tried to use the "Wave Tank" from the shelf, but it creates a following fluid around one of them, and I don't know how should I add the second (or third) one to the sim. Most of the tutorials show how to make it with on...

This one has me stumped - is it possible to move and offset (not retime!) Spectrums and corresponding Foam caches post sim? I'm rendering an Ocean in Karma but need to transform and offset it at render time. For previews I am timeshifting and transforming the Ocean Preview Grid with appli...

Hi! I used displacement mask for redshift in Houdini.But there was such a problem.I don't want displacement where I mask and blend into the ocean smoothly. You can see the problem on the edges of the mesh in the first photo.How can i fix this? I shared the displacement mask and material setu...

As you can see I used a guided ocean layer from the shelf, But the interior volume doesn't obey the extended surface size. How can I fix that?

Hi everyone, I am having an issue I never had to deal with before, since I used to use Arnold and just render from Mantra for many years. Basically I have a few spectra on my ocean and some of them have the volumes going really high (around 30 milion voxels or so) and I was wondering if t...

Hi all.. I'm trying to find the solution, how to control water (or whitewater) shape behaviour around the floating boat. I would like to obtain shape like in top picture on the left. But my results always looks something like on picture bellow, (very extensive side ripples) which I don't want to. No...

Ocean experts - what is really the difference these days between a Guided Ocean and just a Wave Tank? Are Guided Oceans just legacy and no use anymore? Pros and Cons? Cheers!

Hi, I am getting white spots when i add any lights(spot,distant etc) on the ocean surface. Also after using the lights a lot, the displacement also goes at several places. I wont be able to post the file but i can post the setting images or whatever else is needed. I went throug...

I posted about this on the sidefx.com forums and got no response. This is about a feature that SESI has shown and discussed in the Houdini 17 Launch Presentation video. I'll link to the original post and copy it below. https://www.sidefx.com/forum/topic/61375/ "In the Houdini 17 Launch Pre...

So I have been trying to emerge a temple from under the ocean. but I keep getting this weird collision when it comes from below the water. Looked everywhere if anyone had the same issue, but couldn't find anything. The model is from kitbash and I believe I clean it up and polyfill it...

HI, I'm just struggling trying to undersatnd the way he coiuld modified the idea of wave instancing backu up some attribute in order to use them at rendertime (Arnold) timestamp 3:17:36 i understand how to sample some attribute like frequencie, chop etc but didn't get the id...

My ocean foam particles are not flickering, but for some odd reason when I render the foam shader flickers as can be seen in the attached video. Does any one know what's going on here? tmp.mov

Hello As I was going through some tweaking of my Ocean scene, I have discovered a problem. Why my flip fluid area has a different color then my extended ocean?? I have done a few times ago the same things but sometime this problem had appeared! :/ would be nice if someone know...

I'm trying to create an animation of a ship rising out of the water and simulate the water on it. But the animation is so fast that sails and thin ropes are not recognized as collisions. Perhaps raising the substep is a good idea, but is there any other way? Ideally, the collision should be as...

Hello community, I am doing a SpaceX starship rocket landing on an extended ocean (flip sim integrated), right now I am working on the rocket exhaust which should interact with the flip simulation. 1. I have created the pyro simulation of the exhaust flame and now I want to add this py...

Hello there, I have a few problems here: I am trying to make a unlimited ocean scene which I have done without any problems. But now, on the ocean horizon, the water is white for some reason, and I just don't know why it is white, a bug, or I'm just doing something wrong. I tried to m...

Hi, I have a big splash into a large ocean extended and I would like to render separately de mesh into the mask and the other one, but I can't find the way. Does someone know how can I do this? Thank you very much.

I'm using the Ocean Flat Tank Shelf tool to do a flip sim, and then render an extended ocean with the ocean displacement tools. Basically, trying to follow along with the example shown in the Houdini 16 Ocean tools masterclass. The issue I'm having is, when I use the Flattening tools on the partic...

Hello all, I am working on a Ocean scene right now, I have created a unfinite Ocean but now I have a problem. So, there is these strange pattern in the ocean (like in the picture). And now my question: How can I get rid of these patterns? what i have tried so far: 1.) I have try t...

say i have a ocean ,i need do some deform in the ocean surface shader , transform the space from current to object ,then i did some deform work ,then transform it back to current space ,give the new surface position to shading normal , the render have this prob , i think my way is wrong , someone wh...

Hello folks! I used default shelf Guided Ocean layer tool that provided me with the right set up I needed to recreate the moving vessel. The problem is that the waves coming from the Spectra are evaporating over time in sim becaming less and less pronounced. Why is that happening? I tweaked almost e...

I am creating a long animation of a boat on an ocean surface. I am using the new guided ocean surface with Houdini 16 to make use of the extended fluid surface blending to an infinite ocean. I am encountering a couple of problems, one being that as the sim continues the boat becomes a submarine due...

Large ocean render in Houdini with Vray
luckycaard posted a topic in Lighting & Rendering + Solaris!
Hi everyone, I apologize in advance if this is not the right section to post this. I'm trying to find a solution to use Houdini Ocean Tools in Vray. I have the basic scene with the giant grid, which in Mantra is displaced at render time. At first I connected a material node with a basic Vr... -
Hey I have some issues with my scene. As you can see in the image, the ocean looks strange. Also there are a lot of tiles repeating again and again, also inside the Non-Region. In this render the wave high is okay. But in other stuff it is not. You can see this here:...

Hi everyone, I want to render extended ocean with renderman, and I am not sure how to set up spectra and mask bgeo sequences in Pxr surface shader.
