*scratches head* what?

Re: Cybersonics 103 Animation Teaser...
 

HOLY WOW THAT'S AWESOME.

... but what does it do...? lol

Re: Cybersonics 103 Animation Teaser...
 

So.... why use maxscript when you could do most of this with Particle Flow system? Or am i missing something?

Re: Cybersonics 103 Animation Teaser...
 

What the...?

Re: Cybersonics 103 Animation Teaser...
 

Whatever it is, I bet it's awesome... :]

Re: Cybersonics 103 Animation Teaser...
 

i agree with Lev, what is the special secret? Or are you just trying out the max script?

Re: Cybersonics 103 Animation Teaser...
 

MAXscript allows for recurring transformations to occur when you want them to (like when an object nears a target). There are just some things that are really inefficient using the graphical system. That is the nature of a GUI.

This is just an ambigous way of posting the main focus of our storyline without giving it away yet. Hope everyone is doing well and on track for the fast approaching deadline.

Re: Cybersonics 103 Animation Teaser...
 

Hey! Don't bash the GUI :-P

I liked your animation a lot last year and this year it looks like it will be awesome again. Deadlines... oh boy.

Team 75 is attending both the PA and NJ regionals, so I'll see you there! Later.

Re: Cybersonics 103 Animation Teaser...
 

Particle Flow system allows you to have complex procedural behaviors, including finding target and checking for distance - all through GUI ;)

Re: Cybersonics 103 Animation Teaser...
 

Make a scene. Have particles chase a target. Once successful, have them chase another target at random in the scene. Do that without a script and with one event. I want to know how!

Re: Cybersonics 103 Animation Teaser...
 

I would, but right now im too busy with our animation. I'm not sure what exactly you mean by "one event", but YES, i can make such scene with a single particle system, controlled from one place. Particle Flow is the best addition in 3dsmax6, after mental ray.

Re: Cybersonics 103 Animation Teaser...
 

It depends how you set it up in the event manager as to how well it would work, but i bet if you do it right it would work within the GUI, but scripting seems easier then taking the time and testing them out. Good job with the script, did you do it through tutorial??? or was it all purely thought up with a bit of inspiration????

Re: Cybersonics 103 Animation Teaser...
 

No tutorial. Just the reference file and the index.

Re: Cybersonics 103 Animation Teaser...
 

Just finished the scene. Took about 3 minutes to set up, and 5 to tune the settings. no scripting, one particle system.

Here is the scene file: http://web.mit.edu/~levpopov/Public/...rticleflow.max
Here is the rendered sequence (30sec - 11mb, sorry): http://web.mit.edu/~levpopov/Public/...rticleflow.avi


Particle Flow systems are awesome.
