TP Deflectors and Fragment Nodes

OK back in Xpresso add a PDeflector node

I like to right click on the top of the nodes and choose to show names for the ports

Over in attribute manager drag and drop the plane into the Object input box of the deflector

Link a PPass with the “main” particle group to the particle input port of the deflector

Create a PFragment node this is a pseudo emitter

On thes blue input port side of the PFragment add an on port

On the output side (red) of the defelctor add an event port

Now this is a very easily overlooked thing, in PFragement the default threshold is 1 this means you will get no fragment ( oh by the way in all xpresso nodes such as emitters look out for an on check box or an enable check box in object manager !!)

Set the threshold to .5 and now 50 % of our original particles will fragment, 0 means all will fragment

Set up the Deflector and PFragment as shown

Go over your objects in object manager and make editable those that have not been done yet, the sphere I think must be editable to fragment but I am not sure !!

In the deflector settings change the defelector type to object and in the PFragmnet change the From..To +Y -Y

On the output of the PFragment add a Born particle port

Add another PGroup

Add the frag group to this and link up

Well not too good

Now with TP we can always cascade to we can make the frag particles also deflect  and we could add fragments to them and to their children and their children’s children  !! Hmm Biblical :-)

There we go

And here is the full fragmentation setup, you can now add shapes to the fragment or pyrocluster, emit still more fragments etc. etc. have fun
