I'm assuming this is pretty common in production, but maybe not in this way.
Say I have a shipping dock with maybe a boat next to it or something. So you have the ocean out in the distance. Pretty simple, use an Ocean waves. However, how would you go about the up close, more detailed water with splashes and mist banging up against the dock?
I saw that in the ocean waves (Ocean_preview) node, that you can emit points from the grid or surface of the waves that hold velocity information. I was wondering if there is some way to take the velocity information from those points and connect it to a flip fluid to gain waves that connect to the ocean seamlessly?
If anyone has done something like this or knows a better way of going about this I am always open to suggestions.
Thank you for any help.

Houdini Lounge » Best Mid Range GPU for houdini
- JasonH
- 25 posts

I'd truly hate adding onto the grueling conversation of whats the best GPU for Houdini subject, but every subject I have found is mostly about the Quadro's. Which I can't afford. So I decided to look at the 7 series Nvidia cards given that it seems Nvidia has more support overall throughout 3D workflows.
Now, say the average person(me) has a budget under 700 dollars to maintain.
Would it be more logical to get the 780 or the 770 with 4gigs Vram?
when it comes to fluid and particle simulations, does overall speed or the amount of Vram come into play more?
After reading the Houdini system requirements it seems that having more Vram is much better than speed when it comes to OpenCL, but I wanted to get a more updated opinion as well.
Thank you.

The main purpose for me wanting to do this is because 1: I know python already and 2: I have been hearing that Hscript is going out of date.
So I have been digging around in the help docs and through old posts on the forums and I have found some things about using hou.Points and hou.expandString.
Now I have been working on trying to get this expression to go through using Python.
Hscript version:
rand($PT*1400)*0.5 +0.5
My python version:
rand(hou.Points*1400)*0.5+0.5
I changed the expression language to python, but when I try to evaluate the expression I get the error:

Thank you, That actually helps a lot on understanding how to setup the network.
Would you be able to help me out on how I would load a .VDB file into Houdini? For example, the examples from the Open VDB website. I loaded them in through the object import, but I am pretty sure that's not the right way for the object loads but there is no network.

Hello,
I have recently found out about this VDB and it sounds like its an amazing way to work in in Houdini. I haven't really worked very much with Houdini and was wondering if there was any kind of tutorials on this subject? I have already looked through the Siggraph 2013 documents and been to the openVDB website, but I don't think I am fully grasping what this VDB is about. If someone could lead me into the right direction that would be amazing.
Thank you,
Jason Healy

Thank you. I have been putting what you said to work and so far has been working out pretty well.

I am trying to do a brick setup inside a voronoi fracture using a grid in order to create the bricks. I have the brick setup fine and everything works with that, but when I connect the brick tree to the fracture node. the fracture looks nothing like it should. Has anyone ever done this before?

Awesome, Thank you for trying this out. For some reason the school only has version (12.0.581) but I have (12.1.125) at home so I guess ill just have to do it there.
I guess I should have mentioned that the overall effect is going to be a hollow glass sphere filled with a thick liquid that is going to spill out of the sphere when it crashes to the ground.
thank you.

I have a piece of imported geometry from Maya. a simple sphere that was extruded inward. I then changed the sphere into a rigid body. Although, when the sphere hits the ground plane it will just vanish every time. Has anyone ever had this happen to them?
When I use Houdini objects everything will be fine.
I am also using the bullet engine for this, however when I use the RBD engine it works fine.

I am doing a smoke effect where I need the smoke to twist like a tornado. I have tried using the vortex fields, but none of them work the way I need them too. So I was wondering if anyone has ever created a vortex tool that is like the wind tool from the volcano tutorial?

Thank very much for your abrupt response to this situation. You have helped me out so much. I only have 3 weeks to learn this program and its been rough, but you guys have been very helpful and I thank you for that.

Thank you. I didn't know much about the shader before this post so I had to research it a little more to see what you were talking about. Thank you for your help.
Update: I have added a pyro2 shader and I have, for what I think, connected the viewport attributes to the shader through the Utilities>Parm Transfer tab, but it is as if the shader isnt working or something. I am totally confused here.
I have also tried bumping the final amplitude in the density tab and it did nothing.
File included.

Right now I am trying to do a smoke sim in which I am wanting to get a thicker smoke, but when I render out a frame it is very wispy and thin.
I uploaded the scene in case anyone would like to take a look.
Thanks.
