Chops and changing topology

Recommended Posts

Hi,

I have a simulation and I want to filter points position after simulation is finished to remove jitter.

But during simulation I am deleting geometry which is not visible (so that simulation runs quicker).

So I cannot filter P attribute based on ptnum.

Is there some option to run chops by id attribute like in Trail node Attribute to match? So that if point does not exist his value will be set to 0 or last available value instead of using attributes of another point.

 

Thanks,

Juraj

You could make your own id attribute before you delete... And reference that instead...

Hi,

thanks for reply. Creating id attribute is not problem but how can I reference id in chops?

The problem is that if I use Geometry chop in animated mode it creates a curve per point number and it stores it's P attribute. But I have changing point numbers and therefore one curve contains positions of multiple points.

there is Organize by Attribute parm on Geometry CHOP, which should do what you want
