Hello everyone… I have a problem with an RBD packed object inheriting velocity. In the file, I have the attribute active being set by another object, but the velocity doesn't kick in at all.

The velocity works if I remove the point wrangle setting active to 0 and remove the sop solver.
If I try a pop vop or a geo vop, there's some weird velocity behavior that happens.
If I tick on override attribute, the velocity takes off big time and doesn't appear that gravity takes hold.

All I'm looking for is initial velocity once the pieces become active.

I saw a few threads on the side fx forums and this forum, but nothing I saw seems to be working.

EDIT: I noticed in the spreadsheet inside dops that the velocity is resetting to 0 when it's not active, just totally wiping out what I already had. Is that supposed to happen?

So I updated the file and created this video:

the right has Jeff's setup included, the left does not.

Thoughts?

and free software!

I know I'm a little late in the discussion but I have an example scene (had to zip it up because it was too big)
But I feel like I'm on the right track, just missing something but can't put my finger on it.
The aim is to be able to use this with viscous fluids, ie, honey, as I have a modeled dipper I want to have the honey rolling off of. I'm trying to get some massive stickiness into it. Do I need to map this to the stickvelocity rather than collisionvel?
Any improvements to this?

Hello everyone…
I am playing around with the scaling of flip fluids, tried to make a couple of tests, posted in the houdini fx facebook page and trying to understand it so I can achieve what I want..

So what I really need to do is make a 200 foot waterfall. If I scale it correctly then of course it should react correctly, but I want to have my objects manageable.

I could change the units in preferences…that's always an option

How can I get this to sim and react like a 200 foot waterfall without having to scale the objects up?

I had to use mapping software at work to get maps…which didn't really do any good so I went into mudbox and modeled my own based on this pic…

There is also this:

even though it's not being published anymore it looks like it's still a viable option…

I have a solution now…I just can't get the detail I need for Tuolumne Falls, CA…ugh

I've been searching for a way to convert the maps I download, MicroDEM produces memory leaks, PullSDTS is no where to be found….
I'm trying to convert these maps to images to use to create terrain
Does anyone have any suggestions?

For me, the lowest I got was 4.3 and the highest I got was 7.1
and this is after I downloaded the latest nvidia drivers 331.65 for quadro k4000

Success…I found the culprit, Houdini starts up just fine…
the Maxwell Render plugin and RF Plugins aren't compiled yet for Houdini 13.
Thanks everyone for the help!

Just out of curiosity, which driver version is being used?
I have Realflow and it's found some driver versions aren't very good and cause issues with performance so I'm wondering if that's the same here if anyone has tested?
I have 320.86 right now, but I also see some are using other versions.
I got 5.2fps on mine with the same torus setup on the grid.
Can you test with other driver versions and see what happens?

well, I took off both 12.5 and 13.0 and installed 13.0 by itself and still receieve the same error.
The other thing is, both 12.5 and 13.0 are installed in different folders as well.
The only plugin I ever had installed was a Realflow plugin, but I removed before I installed the latest 12.5 and 13.0
I also did a simple test scene with pyro and it seemed to have ran just fine.
Oh wait a sec..I just found I have Maxwell Render plugin for Houdini also, let me get rid of that…

I'm getting this error on the H13 splash screen. I click OK and Houdini starts up…
anyone know how to resolve this?
