Hey folks,

I havn't worked with particles or dynamics before, and could use some advice on how best to approach the following animation:

As you can see, I have a bunch of leaves layed out in an orderly, stationary pattern (that they start out this way is important.). They are then swept up one by one (NOT all at once) along a 'gust of air', adhering to a general path, but not too closely.

I appeal to the wisdom of the masses. General pointers, people? I'll do the heavy lifting - I just need a pointer in the right direction. Thinking Particles? Dynamics?

I've strayed from Cinema, but am having such trouble accomplishing this in Max that I'm thinking maybe Cinema would provide a better solution.

Any advice would be hugely appreciated!

Hmm... Nota looks promising (so many wonderful tools out there from the C4D developer community!), but I can't seem to find a download spot for Nota Lite anywhere (very frustrating.)

Can anyone tell me where to get Nota Lite? Renato says it's on his site, but I can't find it anywhere.

hmm, i just checked, and all you have to do is click on the "GET NOTA LITE NOW" button at the bottom of the page (just underneath the big block of text and on the right hand side, opposite the PayPal button).

Okay, so I must be blind and retarded.

Where on either this page: www.tarabella.it/c4d (http://www.tarabella.it/c4d), or the Nota section, is that link at???

i just put nota in www.c4dplugs.com and it came up with this page : http://www.tarabella.it/c4d/nota/ which has nota lite on it.

Thanks much! Any you'd recommend Nota for the project at hand? Seems promising.

dunno i've never used it (sorry), but a lot of people seem pretty darn happy with it. there's also jenna which has been made free from 3dattack (you'd better do a search for that) which might be more to your liking, or you could do it with thinking particles though as you've never used particles before that might be a little hard for you to do.

Thanks for the input. I hadn't realised Jenna was free now! The things I've missed in my absence. :)

Hey Rocarpen,

For your third frame you could use thinking particles align-to-spline.

I got a lot of help from Monster and the other guys in this thread;

Thread (http://forums.cgsociety.org/showthread.php?t=290672)

For the first two, perhaps you could use simple keyframing? Then merge the animations together? See if the thread helps, there are other similare threads in the XPRESSO/Scripting/Coding Forum. Might at least give you a little inspiration.

Good Luck,

TonyG. :thumbsup:

Man, I stumbled onto a free video tutorial a week or so ago that guides you to creating blowing leaves. I'm sorry that I didn't save it. Anyone know what i'm talking about? It was a company/group that makes video tuts for a number different products.

I'd love to be able to find it again.

You can do this quite easily with a Pfragment if your leaves are textured single polygons.

Lay out the polygons as you like. Select all polygons and combine them to a single object. Shatter this object with Pfragment and let the resulting particles follow a spline.

You can find threads on Pfragment and Spline Follow if you do a search in the c4d forum here. Find two threads I replied to. One had stars following a spline and one had a hand shattering. Those two threads should answer all the questions on Pfragmenting an object and letting particles follow a spline.

I'd go with TP.
Set particles, ie. leaves, have different mass or age and set the wind affect on those. That blows the leaves bye-bye, lighter/older ones first.

Why'd I ever stray from C4D? You guys are great. Those buggers in the Max forums look at topics like this the way a motorist views roadkill. I'll have a try with the described methods (blowing 'em up and then having 'em follow a spline sounds promising, since the leaves are indeed single polygons). I've been checking out some C4D Cafe tuts (great guys, they), and coming to grips w/ TP.

I'll toss some more questions in here, and make this a WIP thread (NDA stuff not-withstanding).

I had some spare time and put together a file which you can use to work out the settings which are right for you.

Wow, creature, you're fantastic. Thanks so much for taking the time to whip that up! I'm playing around with things now, and will post back questions or queries if they come up.

It doesn't create the exact effect wanted here but it's definitely worth a look.

I just gotta chime in to say you are a TP ROCKSTAR! It was so nice of you to take the time to put that file together and share it with the C4D community. Way to go :thumbsup:

Begin a TP/Xpresso newbie, just looking at all those nodes wired together blows my mind.

Anyway, just wanted to say thanks for sharing.

The TP setup of this is not really hard to do.

Open the attachments to this post and I'm sure you'll understand what I did in no time :D

Creature,
That has to be one of the most helpful and lucid TP explainations yet.
Thanks!

You ought to head over to the 3dAttack forum and look through the Xpresso challenges we're up to. Soon, I think, we'll be venturing into TP.

Well, project complete. Not as polished as I'd like, but it's fairly close to the client's storyboard, and given the deadlines I was operating under and the fact that I hadn't worked with particles at all before, I guess it's the best I could hope for.

For some reason though AfterEffects renders out the white background as a light grey. Very annoying. Doesn't show up when rendering out to a sequence of single frames, but refuses to go away (no matter what the setting) when rendering as a movie clip (QuickTime and WMP both).

Thanks again to everyone for your assistance (Creature, especially! I owe you beer(s))

Looks great...nice work! :thumbsup:

Regarding the white background, it sounds like a compression issue. Are you rendering to a compressed format perhaps (like Sorenson?). I usually render out to an uncompressed (ie. animation) format, which produces crystal clear whites. Then when I run it thru Cleaner, Sorenson always "mungies" up my whites to a dirty gray. It takes a few trys in cleaner tweaking contrast and brightness to get the compressed version to match the original.

Yeah, I think you're on the right track. Rendering to a PNG sequence (as I always do for final renders) works fine, producing nice normal whites. It's only when I have AfterEffects spit out direct to a .MOV or .WMP clip that I have the problem. I experimented with both MPEG4 and H.264 compression, without much luck. It's just frustrating when sending drafts to clients and having to add that caveat: "Sorry bout the grey... it'll be white in the final version..."
