specific points along specific curves

[christianl013]

Hello,

I have a bit of a noob question here but I have not been able to find the answer otherwise.

How could I take a particle in a pop network work, plug in a network of curves into the
pop net and have particles only follow velocites of the curve with the corresponding
id attribute?

I have a name attribute for each curve and I have the particle with a matching
name attribute but I have not been able to get the particle to follow the curve
with the matching ID. I thought that I could do it with a pc lookup but it seems
to follow all of the curves in the lookup and not the curve with the matching
ID.

Is there a way to achieve this? any guidance on this would be much appreciated.

Thank you.

Best, Christian

Hi,

I would use xyzdist to sample the curves:

You can use the overload that accepts a prim group where it be an ad-hoc group like so:

"@name=curve05", which would limit the look up to that curve where the name attribute is curve05. You would use this syntax to form the right curve for each point.

Here's an attempt at that setup using only groups.

Thank you guys for your great suggestions. I was able to use the method suggested by animatrix, it worked perfectly, I had to use this with a network of over 100 curves and xyzdist did the trick!
