View Full Version : Allan McKays Fracture tutorial
05-22-2005, 08:38 PM
I followed it and managed to fracture the object just as I wanted it, but I cant seem to get Pflow to display the particles as the meshes. I get a bunch of X's for each fractured mesh. The particles are positioned properly, but they just dont show as meshes when i change the display to geometry in Pflow. Nothing renders either....
I'm using MAX 7, are there differences between MAx 6 maxscript/pflow and 7?

Sounds like your instanced geometry isn't being read into Pflow. Try selecting the Shape Instance node in your flow, and make sure it is using the fractured geometry as it's reference.
hope this helps

i was under the impression that the birth script actually sets the particles to be an array containing the fractured geometry - You shouldn't need a Shape Instance operator.
here's the script you're probably using -
on ChannelsUsed pCont do
pCont.useAge = true
pCont.useTM = true
pCont.useShape = true
on Init pCont do
global ChunksArray = $Box* as array
on Proceed pCont do
t = pCont.getTimeStart() as float
if t < 0 do
NumChunks = ChunksArray.count
for i = 1 to NumChunks do
pCont.particleIndex = pCont.NumParticles()
pCont.particleAge = 0
pCont.particleTM = ChunksArray[i].transform
pCont.particleShape = ChunksArray[i].mesh
on Release pCont do
the global ChunksArray = $Box* as array uses a wildcard selection to get the geometry so if you've called all your pieces "fragment01, fragment02 etc" then you need to edit the birth script to read global ChunksArray = $fragment* as array

here's a little animation with the Particle view i did a while ago using the ideas from that tutorial - i extended it to use two flows - a primary and secondary to simulate the separate chunk sizes. Hope it helps.
