Flip Fluid Waterfall – Particles, Part 4

The next stage in the tutorial required me to create a vopsop node which appears on the network view as vopsop1.

When ever I go into the vopsop node level this is what I am presented with in the image below. My next task was to create a turbnoise node so that it would also appear with the standard global1 and output1 nodes. I used the tab menu in order to create this turbnoise node and the  connected up a few position parameters and then linked the noise parameter to the velocity parameter on the output1 node. Screen Shot 2013-12-20 at 12.04.12Going into the parameters of the turbnoise1 node by clicking on it I was given the option to change which plane the velocity would use I changed this to ZX plane in the option shown below. Screen Shot 2013-12-20 at 12.05.07

The next stage in the turbnoise1 node was to promote some of the parameters this was done by clicking on the icon to the right of the parameter and pressing promote parameter. Screen Shot 2013-12-20 at 12.05.54

The parameters I had to promote were the frequency, offset and amplitude parameters and the display of the particles in the scene view displayed the following effect with lines in the centre of the particles dictating the velocity of the particles. Screen Shot 2013-12-20 at 12.06.36As before I had to go into the offset of the vopsop1 and include an expression in the offset which including $FF/18. An expression is created by double clicking on the text box of whichever parameter you need and just typing.

Going into the source_surface in the EmitterGeo node I was able to view the parameters and change the scale velocity to 25 from 1. Screen Shot 2013-12-20 at 12.12.02Here is now a preview of what my waterfall looks like at this current stage the particles now have velocity applied to them and look a bit more realistic in their movements.
