![]() ![]() This is particularly usefull, when working with millions of particles, because billboards might just be too big. Additionally, you can choose to display particles as points. The type of the particle can also be defined simply by choosing from a drop down list, just like any other particle System. Here's what I got so far:Įmitters are very close to Unity's Shuriken Particle System and offers lots of variety: Point, Edge, Circle, Hemi sphere, Sphere, Box & Mesh. Other features are more tricky to implement and /or need fixing. ![]() So far, I have a bunch of features implemented and ready to go. Let me know if you need any help regarding particle systems in unity by commenting on this blog.I've been working on a GPU Particle System that does NOT require compute shader and can run on Android, iOS, PC, Mac and WebGL. Nested particle systems have a lot of use cases that we will keep exploring in my upcoming blog posts. Their flexibility allows creativity, as we can change their trigger, so they only appear when the parent particle dies, or let them continuously be emitted from the particle of the parent particle, etc. They can also move directions opposite the main particle system or galaxy, which is impossible if you only use a single system. ![]() Nested particle systems are popular because they can run together with different materials, which adds more variety to the particle system. Here, we can see that we finally succeeded in making a nice, foggy and starry particle system that looks like a galaxy. Changing the Size of the Child Particle System for Foggy Effect To do that, we simply need to change the start size to a larger number. We need to resize the child to give the "foggy galaxy" kind of look to our galaxy. Make sure that the scale of the child is the same as the parent particle system. Changing Material of the Child Particle System Then, change the material of the Particle System from the Renderer menu to the SmallStarCluster material that we have made. So, let's duplicate our galaxy Particle System and make it a child of our current particle system. To do this, we need to add another particle system to the mix with a foggy star cluster material as a child. We need to add a few foggy star clusters to make it more complex. But it still looks like a primitive model of a galaxy. The model above shows our stars moving in a spiral motion. You can set Start Size to automatically generate randomly, as shown below. The size of our stars are controlled using their Start Size. Applying the BigStar Material to the Particle Systemīut, the stars are all of the same sizes. Select the BigStar material with the parameters shown below. Go to the Renderer section of the particle system where you will find the Material field. Setting up Spiral Galaxy MaterialsĪfter setting up a basic shape and rotation for our galaxy in Part 1, let's start Part 2 by learning how to put the materials in our particle system. Make sure you also start with something similar. These are the materials that we will be using for this tutorial. In this blog, we will learn how to add materials to the particle system we made in Part 1 and further refine it to make it look more like a galaxy. This is Part 2 of a two-part series that details the creation of a Galaxy in Unity using a Particle system. ![]()
