If anyone's interested. All procedural, none of it Behaviour. I'll write up
some stuff on it when I get time.

I remember Kim showing some really cool crowd stuff using 
particles at the TD Love Tour.  Nice stuff for having 
characters avoid obstacles and having simple crowd flow.

My suggestion would be to buy Massive Jet and get some of the agents 
they have on library as it is literally plug and play.

I have been using it for more than 2 years (the full package 
      
it is) and 
    
has been so far great, just great.

PRMan obviously is a "funny" factor, specially as it is our 
      
case when 
    
you use version 11.3, quite buggy and annoying but we 
      
managed to iron 
    
it with a bit of patience.

This will all change this year with the new film quality hardware 
rendering and MI export plus many many other things.

In terms of easy of use, massive is very easy to learn, no 
      
scripting at 
    
all although you can write python code to automate things.

If you plan to use it just as it is now, buy 3Delight 
      
instead of PRMan, 
    
it is much better and faster for crowds.

hope it helps

I remember Adrian saying something about hippies and that 
        
they should 
    
make a renderer... one cloudy day in the tombs of the mill :)

I don't have a specific task right now, but merly looking 
        
into what's 
    
out there and what the cost will be to get it up and 
        
running. I would 
    
think that the most basic things would be to make people walk in a 
pattern or fill bakgrounds with thousands of people.
I'm also wondering if it could be used to have thousands of spiders 
crawling on floors/celings etc.

And since we hired Arvid Björn recently I'll dump most of 
        
the coding 
    
onto him :)

Behaviour isn't for the faint hearted either.

Depends on what you want to do, Stephan. Many crowd sims are just 
things running in a direction, maybe a bit of direction 
          
control to avoid scenery.
    
If this is what you're after then my experience has been 
          
to stay away 
    
>from Behaviour, look for other methods. Otherwise, if you need 
        
complex interaction then I'd go for Behaviour, simply because it's 
closer to xsi and mental ray. But .... Make sure you get some 
experienced help. You *will* need to drive it from 
          
scripts, almost entirely.

my £0.02

massive is not for the feint hearted, especially as currently you 
need a renderman compliant renderer.....
(i did charging cavalry, from mocap of real horses through to 
rendering in prman,& i still have nightmares...) however, 
            
a mental 
    
ray version is on the cards, and with massive jet, you get a shed 
load of out of the box mocap and agents, all setup and 
            
ready to go!
    
jet doesn't allow you to modify the 'brains" on the agents, so 
you're stuck with what massive give you action wise but it really 
'should' be point and click (here's my terrain, here's 
            
where i want 
    
my guys to start, there's a thing for them to avoid/attack etc)

(you can modify the geometry and textures of course!)

and on their site there is news about mayhem and sword fighting 
agents to soon be released, so expect lord of the rings 
            
type battle 
    
sequences in eastenders soon....

OK My 2 cents for what it's worth!

Bugz for Maya is very limited, I quickly looked at it - not
         

              
much cop at
       

            
all (unless I missed something) - But cool for free!

Behaviour - comes free with Advanced which is cool - it is
         

              
difficult to
       

            
use, as you may well need to get into piccolo scripting,
         

              
unless you are
       

            
doing such basic stuff that can use the basic point and
         

              
click method!!
       

            
BUT Needs MR tokens to render with, unless you do want to
         

              
write out data
       

            
to reimport into XSI and map onto characters - which really
         

              
limits the
       

            
numbers of your crowd scenes, as you obviously need to be
         

              
able to render
       

            
them!!  If you do have MR tokens, it is quite cool - as it
         

              
seems to be
       

            
able to render large data pretty quickly with no real RAM
         

              
problems, as
       

            
it exports MI files!!!

Massive - The Ferrari of them all - I have not seen it, but
         

              
have spoken
       

            
to them - they are supposed to be coming out with a MR
         

              
version this year
       

            
- now you need to have a Renderman Variant to render with!!
         

              
Supposed to
       

            
come with lots of prebuilt libraries of stuff - and is as
         

              
far as I can
       

            
tell not based upon scripting!!!!!  Come down in price - 
              
so not too 
    
bad!!  And if you look at the likes of Air - pretty good!!

Subject: crowd simulations

Hi everyone,

I'm starting to collect some information regarding crowd 
simulations and I was wondering if people with 
              
experience here on 
    
the list could give me some insight and share some of the 
experiences. It's always good to be prepared if the 
              
situation will 
    
come up... and I hear more and more questions from 
              
various clients regaring crowds.
    
Right now there are a few options which will all cost money
         

              
for us :)
       

            
1.) Behavior (upgrade to advanced)

2.) Massive Jet

3.) Maya (getting Maya mental ray render lincenses) using 
http://www.kolve.com/mp_brainbugz/brainbugz.htm

Since we have little (read "zero, njet, nada,") experience
         

              
with any of
       

            
these it would be helpful to hear what you people think. 
              
It's one 
    
thing what the PR person for each reseller tells you 
              
(according to 
    
them there are no problems at all....). And there is also a 
question abuot rendering licenses, can they all use 
              
mental ray? I 
    
waguely remember a discussion that Behavior needed a standalone 
version of mental ray? And can Massive render with 
              
mental ray or do 
    
we need to use Renderman?

Anyhow... lot's of questions.

stefan andersson
