View Full Version : Uniform Flocking in 2015.3

I'm trying to find out if there's a way for the particles to flock in and uniformly fit on my mesh. Basically, i'm hoping to create an animation of a house being built without having to hand-animate it piece by piece, with each particle being one brick. I have a specific house model i'd like it to build into, and have it set as the Flock Director, but I can't seem to find a way to get the particles to distribute evenly across the model. As it is now, the particles attract to points on the model. I have a basic box generator set up above the house, so the bricks will seem to sort of appear from the sky and fall into place. Is there a way to achieve this with flocking, or should I be looking at regular particle emitters instead?

For clarification, i'd like to achieve a similar effect to this Blender tutorial.

I'm not sure about the flocking, but what I've done is have my final model set then use a jitter or some kind of turbulence effect to scatter the items and reverse the playback.

DP Kit Part move. I've used it for exactly this type of animation before.

I didn't have the items fly in like you want, but certainly could have.

I also recommend checking out bryphi77 youtube videos, he has a lot of good info on this type of effect.

Or you could do gravity simulations on the bricks, save out the mdd files, the arrange them how you want in a new scene. I used this technique years ago to create the logo animation below.

Thanks for all the replies! I probably should have clarified, but the model i'm using is a few big solid pieces, and the bricks are all just a texture and bump. I've got a few different house models made the same way, so we were hoping we could just choose one to use as an invisible base and have the bricks build its shape, that's why I turned to particles for a solution. I'll attach a screenshot of one of the models to this post as an example. I can make a new model with individual bricks if that would be easiest, but I wanted to see if there was an alternative option with particles or something similar first.

Sounds to me like this is a job for Bryphi77.

Animating this sort of thing is exactly the kind of thing he does via nodes. He may have a video (or several) that would help do what you're after.

Here's my take using Part Move: https://www.youtube.com/watch?v=Dag_j7l8eo0

Really have my fingers crossed we hear from Denis on LW2018 soon!!

Okay, so i've taken a look at Bryphi's channel. I tried to achieve what i'm after by following his poly flip and some of the wire build tutorials, but I can't seem to apply it properly to my model. He has one video that has an effect similar to what i'd like to use, "Building buildings (ogl test)" and he said he planned to make a tutorial on it, but if he did i'm not seeing it on his channel. I thought the poly flip video might be it, but I can't get that effect to transfer properly to a three-dimensional object where i'd like the flip to happen on the Y axis.

Mark, watching your video is my next step.

Update: I've mostly applied the poly flipper tutorial to my model now. I was missing that each poly in his model was an individual object, so once I cut up my model some and unwelded the points, voila! The only issue i'm having now is that some of the polys show through the back side of the model when flipped, since they just flip around instead of turning invisible. I haven't finished the whole tutorial yet, as I was stuck on this part until a few minutes ago, so he may cover this further in once he gets to the sphere.

Sometimes Bryphi see's issues on here and makes videos in response; if you're lucky he may see this :)

He has and it’s a really nice one!
