On a SP3, trying to install that driver doesn't work; it gives a message saying “Cannot install this driver on this hardware”. Are you guys doing something special for the SP2? I'm guessing the 3 has some sort of special restrictions on it, but it'd be nice if it didn't.
Thanks!

Hey guys, super helpful thread, thanks! I'm trying to extend this to inherit the initial velocity of each packed prim once they become active. But primitives that get activated over the course of a simulation don't inherit v when they start to sim.
Is there something I'm missing on the object to get each piece to inherit velocity when its activated? This file is netvudu's, modified slightly.
Thanks!

This is really impressive. Can't wait to try it out, both to model, and to learn from how you did it!

If you need to select outside edges procedurally, the Group SOP set to Unshared Edges, like the screenshot shows (make sure you uncheck Enable under the Numbers tab, which is on by default).
Also, if the new edge loop select doesn't work with a mesh, send a bug report to sidefx with the mesh if possible. Might be a bug?

Scatter 2.0 in H14 has some relax options, so that's why it looks so different. They're toward the bottom of the parameter window.
Does turning that off do what you expected?

Maybe try saving it to BGEO first, then to VDB? Also you could try using the gconvert utility, see if that works.
I have no idea if either of those would work, just throwing darts in the dark
Sounds like a bug to send to support. What OS are you using? Houdini build and/or gcc version (if linux)? Many tools/renderers don't work with OpenVDB 3.0 yet, so the H13 export option should be getting lots of use (at least under certain conditions).

That's strange, I've been running fine under Linux Mint with a 765M card (with Nvidia drivers).
Just curious, what language/locale is your system set to? I know it's not likely, but maybe there's some obscure incompatibility between H14, Qt, and some other libraries under certain languages?

Gotta start somewhere, many tools have started out slow (voronoi fracture). While I don't know the answer, here are some ideas that might help inform some expectations:
- many tools have started this way (voronoi) then improved
- Houdini often starts with flexibility first (if they have to choose), then make it fast (see FLIP, PYRO)
- Many users/pipelines are built around this flexibility first mentality, then either through feedback or custom development speed up shore code/node paths
- it's easier to maintain OTLs vs c++ DSO ( one of many reasons, I think, we'll see more vex nodes like point deform and pop grains)
- it was good enough for the small number of testers at first
- Bug reports and RFEs more numerous in other areas/features
Like has been said many times, submit bug reports and rfes! Hopefully developers generously being so active on the forums doesn't stop folks from submitting them!

Do you have a hip file you could share?
I tend to use VDB from Particles, as I just didn't quite feel like I had the control/speed I wanted. I'm not sure what it's doing under the hood (it's not a SOP coming from the OpenVDB project, afaik); maybe a developer could talk about what's going on. I wasn't paying attention, and thought it was simply an OTL wrapper (didn't it used to be?), but now it's a C++ node.
Also, there are some OpenVDB slides/notes that have good suggestions and guidelines for meshing fluids: http://www.openvdb.org/documentation/ [openvdb.org]

Here's a little render: https://vimeo.com/119619724 [vimeo.com]
Ah, got it! That makes sense
Great to know, thanks!
Submitted via webform, I'll post an RFE number when I get one back from support.
Thanks!
*edit*
Attached my hip file that corresponds to the Vimeo movie.

Then just tweak kvisc and not worry about it the viscosity behavior changing when you change density.
Ah, got it! That makes sense
johner
It's more accurate for high viscosity (and matches cloth's similar default). But for low viscosity like this (and if you want to run the solver on the GPU) it can be a bit faster to run in 32-bit.
Great to know, thanks!
johner
That's an interesting RFE (please submit it), not sure how hard it would be. I usually just use planes and slide them around to see the parts I'm interested in.

Two other in-houdini ideas:

Wow! That's exactly what I where I've been trying to go; and the explanations are extremely helpful, thank you johnr! I think that my block was diving too deep (deeper than jason's naiad test), so it was collecting way more foam than his. I tried animating it to be more shallow, but I suppose I could only transfer to points near the surface as well.
Just a couple of things I don't fully understand:
- Is kvisc an attribute the solver knows about? I thought the FLIP Solver had a chart of attributes it inherits (ala Bullet and POP Solvers), but maybe I'm imagining it?
- The optimization tips are great; for viscosity accuracy, is there a reason the default is 64-bit, and not 32-bit?
- For visualizing the different fields, is it possible those could get a 3d mode that isn't smoke? I'd really like to see it with a field of points changing color (or maybe even scaling up/down); it's so handy looking at vel this way, it'd be great to see scalars in 3d as well. I peaked inside, but couldn't find if those Visualizers could be modified…
I appreciate the detailed answers/help, it's really helped me get my head wrapped around this!
pavel, thanks for the suggestion and links! I'll check those out!

I'm working on replicating this Naiad test (https://vimeo.com/25020677 [vimeo.com]), and after getting some help over on odforce (http://forums.odforce.net/topic/21936-varied-density-in-flip-low-density-not-rising/?p=130572 [forums.odforce.net], but I'm hitting two issues now:
- The foam doesn't collect together very well; I've got super high viscosity (both high point values, and a high multiplier on the solver), but there must be something else I'm missing?
- Although I can get the less dense foam to rise up, it's not very fast; but I can only get it to go slow, or shoot out like a cannon. Is there some way to direct the foam to float up to the top very quickly, but then just rest once it gets there?
Thanks!

Well, here's to hoping PySide gets updated with a quickness before I consider investing in a deskbrick.
The PySide list has some talk come up once in a while, but the last I heard, Digia doesn't seem to be driving PySide for Qt5, and no other companies have stepped up to fund developer time. No idea when it'll happen, but I don't think it will be very soon with funded developer time (which is what PyQt5 has, since that developer makes money from the commercially licensed PyQt5).
