Questions tagged [particles]

Questions pertaining to a group of particles which can be used to simulate a system of chaotic objects(known as particle systems). Particle systems in Blender are robust and full of settings.

Particles are lots of items emitted from mesh objects, typically in the thousands. Each particle can be a point of light or a mesh, and be joined or dynamic. They may react to many different influences and forces, and have the notion of a lifespan. Dynamic particles can represent fire, smoke, mist, and other things such as dust or magic spells.

Hair type particles are a subset of regular particles. Hair systems form curves that can represent hair, fur, grass and bristles.

How to control hair particle position?

I am trying to make some grass. I want to have grass only near the edges of my plane and not on the center. Is any way to do that? Or I have to split the plane and make different objects?

Making hair go straight up instead of following the shape?

So I'm making trees on a hill. But from what I know, trees grow straight up, and not at an angle. So how would you make the hair particles go straight up and not at an angle. Here's an example of the problem I'm having. I would like the trees…

Is there a way to simulate convection with a particle system?

As stated in the title, I want a particle system that will have particles heat up and rise, and then sink when they cool. How can I simulate this? Additionally, I want to make sure the particles attract each other and move around on the x and y…

Is it possible to recursively instance object particles?

I have a seed object with some particle hair strands. I've specified this object to be instanced in another particle system, then specified that object to be instanced in yet another particle system. To clarify: I have a cube with hairs…

How can you change the curve resolution of hair particles?

How can I change the curve resolution of hair particles? It seems that by default, hair consists of 4 segments. Which is fine most of the time, but for long hair this does not work at all, as in this picture. The segments spinner at the very top…

How to use emitter for generating thick forest so that trees would not intersect?

I am trying to make thick forest in blender using emitter or hair emitter. The problem is that with huge ammount of trees they intersect with each other and I do not want that to happen. I did use various setting, groups and tricks without success.…

Abstract Wave with Particle System

I want to create a wave made out of particles/dots. The wave should look like this: I tried to achieve this effect by adding an ocean modifier to a plane. Then I added a particle system to the plane but now I don't know how to go on. How can I make…

Even hair particle distribution

I'm trying to get my hair particles to distribute evenly across a surface of a object. The problem is that there's only three ways to distribute particles: Verts, Faces, and Volume. My mesh surface is not even in terms of vertices or faces, and…

How to affect particle size over time?

I'd like to spawn particles that change size over time. It would be nice if I could have complete control over how big they are at each percentage of their lifetime, but that is not a necessary feature. (I'm rendering the particles as objects.)

How to make particles fall like snow

I'm trying to make a blender animation for Christmas, so I am kind of pressed for time. It is snowing in the scene, so I have watched tutorials on the particles. I tried it, but it looked too much like rain when I plated the animation. Snow is…
