Freezing Particle Instances?

Thanks for pointing out the fact that Essential has Particles now - I have
Advanced but deliver models to a company that have both and assumed I had to
stay away from Particles for that reason.

I am fully aware of the risk of slowdown but I stay below 30K triangles total
so it is not really a problem. I agree that for other purposes it would make
sense to stick with BBoxes and Instances, but for this I need to model some
more after creating the basic surface.

This is a test patch showing what I need to create:

There are other ways of getting to where I want to go and for this I eventually
went with Helges Scatter tool. It requires me to model base geometry with
fairly evenly sized and spaced polygons in order to achieve the look I need,
which is why I explored the Particle way. See this test displaying how Scatter
works:

http://colorshopvfx.dk/XSI/Bulepels_test02.jpg

Basically I was curious to know if there was a way to use Particle for this and
other modeling purposes, as I find that procedural modeling and especially
random duplicator tools are somewhat lacking in XSI. It would really make sense
to allow "full" use of the positioning and randomizing functionality of the
Particle system also for modeling purposes, but maybe that is just me ;)

If Montreal has that particular problem maybe it's time they empty their
wallets and go for something bigger than 14" monitors ;D

 Essentials has particles since v2, so if that’s the only reason keeping you
from keeping it particles, it’s a non issue

 You also realize that moving from bounding boxes in the GUI and instances In
rendering to real geometry is gonna be a quite massive slowdown under every
aspect, don’t you ?

 

 Last but not least, if you REALLY need to convert to objects, your only hope
is in scripting.

 No “expand instances on particles into a cloud of objects” command is
implemented yet, I heard Montreal was planning to put one in, but then they
gave up because there was nowhere in the interface to fit such a long name.

 Subject: Freezing Particle Instances?

 

 I have used particle emmision to model an uneven surface from a group of
irregular spheres, using instances. Question is, is there a way to expand these
instances to regular geometry so I no longer need the particle system? This is
because I want to continue modeling on the new surface and I would like to get
rid of the particles so I also have the option of working with the model in XSI
Essential.

 

 I tried Isners Instance Duplication script but get an error on line 39 -
maybe it does not work with Particle Instances...

 

 Any suggestions?

 

 TIA!
