Add a particle birth output port to the emitter

Create a PGroup

Link the particle birth to the PGroup

At the top of the xpresso window you will find under Custom the thinking particle settings, this is a very important part of the exercise, here we can create our relevant particle groups allowing us to interact with each group individually

Lets add our first group and call it main

Now drag and drop “main” from the settings window into the PGroup node

Create another group inside the TP settings and call it “frag”

Change the color of the frag group to red so we can distinguish them later in the main view

Add a PPass node to the Xpresso window

Drag and drop the main group from TP settings into here

Add a PShape node

Create a sphere
