Ho can I use a group inside a dop network? Feb. 22, 2016, 7:13 a.m.

Here is the thing:

I have an object, it's cutted into pieces and I'm defining it as cloth, so far so good, the simulation is running pretty well and I like the effect, now in the Geometry node for that object I create a group called “inside” and in the DOP network I'm trying to limit the “Finite Element Solver” to that group so whne the geometry comes into that group it starts being simulated but if it's not it won't be simulated.

The problem I've found is that the “Cloth Object” node is not importing groups from the geometry, I created also an Attribute wich it's value is “1” id the points are inside that group and is “0” in case they are not but I'm a bit lost on how can I use that Attribute to do what I want.

Thanks in advance for your help!

Cheers.

POPVOP affecting outside defined group... why? Feb. 7, 2016, 3:38 p.m.

Thanks for the idea, how can I check that?

I ask because there is no list to select points, primitives, etc…

But anyways, the wrangler is working because if I check the spreadsheet in the “POP Steer Seek” the group “seek”is marked as 0 in each point inside the group “seeking”

Is weird because in the “POP VOP” I apply a turbulent noise but I also add a bit of velocity to Y, so the particles raises up, and that addition is working correctly, it's activated while in the group “seek” and it's not affecting while in the group “seeking”, so it seems it's related to the Turbulent Noise because it keeps working even when the points don't belong to the designed group…

Cheers.

POPVOP affecting outside defined group... why? Feb. 7, 2016, 11:15 a.m.

Hi there.

I have a pop net, inside I define a group of particles, “seek”, and I apply to them a “Pop Vop” to apply a noise to their velocity, the effect is the one I'm looking for, but then I put thos particles in a different group “seeking”, and with a “POP Wrangle” I remove the points inside the group “seeking” from the group “seek”, after that there is a POP Steer Seek to make the particles go after a shape, and it works except the “Turbulent Noise” inside the “POP VOP” is still affecting the particles, even when the “POP VOP” should be affecting just the group “seek”.

I'm a bit desperate to understand this, some ideas please?

I tried also to detect inside the “POP VOP” if the particles are inside the group “seek” but I can't find a way to do that.

Thanks in advance!

P.D.: I posted the same question at OD Force, just in case you find this familiar, but no answers at the moment.
