Music to control Vellum

[timur04]

So I have a simple setup that almost works.. I want values from music to drive vellum balloons up and down. Not all at once, but like an EQ.

The problem, DOPS network freezes the values, so its stuck with the original values that are on the very first frame.

How do I make the music lift the balloon, then gravity would pull it back down?

I've included by scene.

you may need to lock your resample1 CHOP so that the curves are saved into hip file when posting to forums, otherwise we don't know what values you are dealing with

however to get the values into DOPs:

- disconnect or delete sopsolver1

- on your popwrangle1 set Inputs/Input1 to First Context Geometry and use code like this:

float dist = point(0, "dist", @ptnum);
v@force.y += dist*chf("strength");

Perfect, this is exactly what I needed!

Also, I have the color randomly flickering before it is piped into dops. What is the bit of code I can write that would reference that?

 

Thanks!

since your Cd attrib is promitive, you can either add this line into your code

v@Cd = prim(0, "Cd", @primnum);

or you can promote your Cd to point right after color1 and use this line

v@Cd = point(0, "Cd", @ptnum);

or to keep it on primitive you can also run the first one in Geometry Wrangle DOP that runs over primitives
