Hej i found a cool video on vimeo:
I was wondering how to achieve this effect.
At the first moment it looks like a hires model with a lot polygons which got displaced?
But i'm not sure here.

i have a grain sande box with is starting to simulate at the first frame. I need later after 600 Frames.
In the " impulse activation tab" i have here
What should i add to activate it at frame 600?

Hi - i created particles colors with the Attribwrangle VEXspression:
// Color from Bounding Box
@Cd = relbbox(0, @P);
this code basicly created a bounding box based on all particles positions in the scene. (it changes the color - because the particle are moving in space)
How to define an own bounding box (size of the bounding box) - based on primitive-cube for example?
All the best

i added my file....
Is it possible to add a target position to the grains like "fem" or "cloth" has?

Hello guys, I wanted to use the pop attract in a grain simulation. I have a simple simulation with grain, which are falling down. After a specific frame I wanted to let the particles go back dynamical to the exact start position. I thought it’s possible with the pop-atttactor node. I’m the source tab, I can choose atttaction type: particles. Here I link to the rest position of the first frame of the grain particles.
This doesn’t work for me.
All the best

no - not working :-(
Hello guys, i wanted to delete some points on a spline - my problem is that the spline always wanted to close itself and adds some bigger splines between the gabs ( i don't want it) .
How can fix it?

Hello guys, is it possible to drive the strenght of the smooth sop based on attributes (color)?
I was trying to type from vex expressions..but he did not use it.

i have a copy stamp and wanted to build a look at function for the copys to a specific point or geometry - the rotation for each copy should be applyed only on the Y-Axis .
Is there a special node for this? How does it work?
all the best.

someone know how to setup a defined gravity field for an FEM simulation?
I tied it with a mask field in the gravity note but it doen't work for FEM ( with an RDB Object it works perfectly)?
Scenefile is attached:
thanks so far!

Hello guys, i was looking for an option to drive particles(point) like a pyro Animation. Is there a option to do this in Houdini? I know that Houdini has a points from volume - node...but these is static an change the position on every Frame. Is there any solution for it?

Hi, i was trying to group particles from a flipfluidobject, but without luck.
My goal is to add to differnet gravities with 2 Popforces + 2 PopGroups.
The particles from the left half of my flipfluidobject should have a positive gravity and the right part should have a negative grafity.
Does anyone has an solution for this?

anybody still have an idea?
i found a better example for this:

Hej guys , i was looking for an option to add costume velocity fields to a grain solver. I a a tutorial, but it did not work for grains.
Does anyone has a tip to do it with grains?
Posted July 6, 2017
yes i was thinking about this - but i'm not sure how to animate that in sop-level so that it looks like this:
bend deformer does not working i think.

Hi guys, is it possible to use animated contraints with Fem?
I was trying to contraints the head of the 2 tubes (image) to an rotating cube, so that both tubes are winding together like a rope.
With fem targets geo i had no luck. :-(
Is this possible?

Hello guys, i was trying to add a rdb-collider to a cloth animation...without luck.
Is it possible to combine both so that hej interact physical correct?
Posted May 21, 2017
Thank you this is working...but not with an animated noise.
Do you know if this is possible too?

I have a cloth object and addet a target object in the DOP Network.
Is it possible to control the transformation to the target-object ( Target Stiffness) with a animated noise?
Posted May 18, 2017
Hmm, no no chance to get ist working. I also try the self tool "look at".
The people are not looking at my object.

Does anyone know how to setup a vdb morph with the " vdbmorphsdf "- NODE and a mask?
Never got it working.
Hello guys, i am playing around with crowds in houdini.
I wanted to achieve, that my crowdsource people are placed in a circle around a specific object - and all faces have to look at the object.
Does anyone know how to do that?
