Yes I was aiming that the MADNESS reaction..
Uhm I think I understand, the one from DOPS has been given free because of the DOP environment, I dont know exactly why.. if you would like to explain this.. please..
I still dont really understand the trail SOP's velocity, when I emit particles from the surface afterwards I noticed it inherits the velocity of my object. Which is pretty neat..
But my main goal was actually using a velocity variable inside anything I like, for example I would like to increase the amount of particles emitted from an object with the value of my velocity.
Trough the DOP's velocity it works out, now my next challenge would be through a SOP local variable (if it is a local variable).
Ive got this scene in front of me, an Utah teapot, Ive generated some noise in its Y axis so I have a little varience in the animation.
Then I've generated particles from the surface by connecting it as a first imput.
What I want to do now is inside the popnet, there's a source node using the first imput connection, now In this node there should be a Const Birth Rate parameter. I would like to use my Y velocity as a value.
Many thanks again for your time and patience!
