Hey Julca that was very fast fix, it works fine on SI 2013!
Test :

hi, i have this one =( on Si 2013 64bit
' ERROR : 21000-EDIT-AddICECompoundNode - Traceback (most recent call last):

UPD: sorry, its ok! just restart XSI after instal addon =)

Hi julca,
Can you just explain the number and density ? It seems everytime I move one the other moves as well so I don't understand. I would like to use a very specific number, is that possible ?
Thanks please excuse my simple question. Awesome tool by the way !

Of course,
The number and density parameters does the same thing but in two differents ways :
- - If you adjust the density (= number by xsi unit), then the number parameter are adjusted to reflect exactly the density according to your emitter area.
A grid emitter (1*1) with a density of 1 = 1 particle
A grid emitter (2*2) with a density of 1 = 4 particles
A grid emitter (2*2) with a density of 2 = 8 particles
etc.
So if you change your emitter object, you keep your ratio of particles and so, the aspect of your scattering.
- - If you want a specific number (without considering all filters parameters),
just edit the number parameter (and the density will be adjust to reflect this number).
Hope that's clear.
If you have any other questions I'm available to answer it.

So the true number is just the number parameter and the density useful when wanting to maintain a density despite actual number and emitter ? Wow, very cool !
Thanks

Hi julca, one more question ... How can you control the specific number of instances within the various shapes ? E.G. If you have 10 shapes, how can you have say 12 of shape 1, 3 of shape 2, 9 of shape 3 etc ?
Thanks

Hi, you can use the shape's weight to do that.
Set your number parameter equal to the sum of each shape's weight number.
Like in the screenshot below, you have 10 total particles and the sum of each shape's weight (3+2+5) give you 10.
But you need to update manually the number parameter at each shape's weight modification.
I hope that help you.

Hi julca, I have tried that but I'm not getting the same results. I have 38 different shapes(people on cards) and when I load them up I get this ... See image.
Am i doing something wrong ?
Thanks

If you set the number parameter at 38, you're should be ok.
But, my last suggestion works without apply the filters (closest, inside, etc.).
The number parameter is the number of particles before apply any filters.

I tried setting the number to 38 and that image shows the results in the shapes page. It's strange. It could be something I'm doing but it's a pretty simple setup that I'm using. I'll try again just to double check
Cheers

Hi julca,
Yeah, turned off any other settings, put in 38 and I'm still getting strange readings ... arrrgh Help. Your plugin or addon is so fantastic, it's just this one little snag for me ... any other suggestions

Oups, you're right !
I select shape ID by random and here the weight just influence the probability.
Let me take the time to find a workaround/update.

Hi cheeseburger,
I've updated the link of first post (version 1.2):
- Add a new emission parameter "Exact Shape Weight Sum" that drive the number of particles with the sum of all shapes's weight.
It also strictly set the number of shapes accordingly their weight.
- Correct update of shape info (number and percentage for each) when "Fractal Shape Selection" are enabled/disabled.
Now you can use shape's weight as the exact number of shape.
Like below, I have 6 shapes, the first one with a weight of 3 and the 5 others with a weight of 1.
The total of 8 (3+1+1+1+1+1) is automatically updated.
Thanks for your feedback.
Cheers.
