Hi,
the Dissolve SOP has a ‘Remove Inline Points’ parameter
that should do the job.

Hi,
an option could be to use the AttribTransfer SOP, it works by proximity
so you don't need UVs.

Hi Rob,
try to set the ‘Num Expressions’ param in the Group tab to 2
and set expression1 = icmax(0,0) and expression2 = icmin(0,1).
It should work.

Hi,
the problem seems to be related to the sprintf evaluation with the ‘+’ operator.
I've tried the following code and it seems to work fine.
sop vexeg( string pcloud_texture = “op:`opinputpath('.',0)`”;
float maxdist = 100.0; int maxpnts = 10; )
{
int src_number = ptnum;
int handle = pcopen(pcloud_texture, “P”, P, maxdist, (int)maxpnts);
string tst_str = “”;
string tmp;
while (pciterate(handle) )
{
tmp = sprintf(“%d;”, src_number);
tst_str = tst_str + tmp;
}
addattribute(“tst”, tst_str);
}
sop vexeg( string pcloud_texture = “op:`opinputpath('.',0)`”;
float maxdist = 100.0; int maxpnts = 10; )
{
int src_number = ptnum;
int handle = pcopen(pcloud_texture, “P”, P, maxdist, (int)maxpnts);
string tst_str = “”;
while (pciterate(handle) )
{
tst_str = concat( tst_str, sprintf(“%d;”, src_number) );
}
addattribute(“tst”, tst_str);
}

yes, it seems only a visualization problem.
I've used the uv node in my first scene, but I think it makes no difference as the fur setup adds a uvTexture automatically in the input_skin sub-node.
thanks.

Thank you for your reply.
Maybe the crash is due to a different release.
However the scene setup is very simple.
Create a grid, attach fur.
Create a cop network with a shape node (circle) and animate scale or/and translation.
In the fur node set the length map parameter to:
opobj/cop2net1/shape1
The first frame should work fine, but playing the animation it doesn't.

Hi all,
I'm trying to use a COP network to drive the length map of a fur object.
The cop net is animated (a shape changing scale).
The length map seems to work fine at the first frame, but when I play the animation,
the it behaves quite strangely.
Am I doing something wrong? or am I missing something ?
thanks in advance

Hi,
you could create the complementary group using the combine tab in the group sop and then use one or the other.

Hi all,
another solution (a little less elegant) might be to use a Dynamics Chop (in Cached mode) to get simulation data and a Warp Chop to modify simulation time.
I've attached a couple of example files:
If chop isn't working go to sphere_chop -> chopnet1 -> dynamics1 -> update.
Inside the chopnet the warp_rate_channel controls the warp.

Hi,
reading the documentation I've found this:
- ODE works with Houdini’s rigid body objects, static objects, and RBD point objects.
- ODE does not support glue or fracturing.
( Dynamics Using the ODE solver for RBD http://localhost:48626/dynamics/ode_solver [localhost] )
Try to use a RBD Point Object, it should work.

Swann_
Couple notes here. You don't have to use $ every time you create variable. You use it only when you want acces some parameter that is connected or created on actual node that you placing this code. So when you created “int i” don't use $i since you are not importing it from somewhere, its just variable that you created here. Also when you using global P and N that are not modified you don't have to import them from your input, just write P and it will work.
Thank you Swann_ for your clarification.

Hi,
here's attached a simple example using Inline Vex Code.
It isn't exactly what you asked for but I hope it can be useful in some way.

Hi,
I've just made a simple test and it seems that the problem is the basic_liquid material that doesn't take into account the Cd attribute.
Try this: in the basic_liquid material, dive inside the net and, in the atten parameter node, set the Paramenter Name to Cd. If this trick works, you can modify a bit the material net in order to obtain the desired result.
Let me know, I'm interested in your test.
