Summary
In this chapter, we discussed two different ways to create particle systems: using regular particle systems and VFX Graph. We used them to simulate different fluid phenomena, such as fire, a waterfall, smoke, and rain. The idea is to combine particle systems with meshes to generate all the possible props needed for your scene. Also, as you can imagine, creating these kinds of effects professionally requires you to go deeper.
If you want to dedicate yourself to this (another part of the job of a technical artist), you will need to learn how to create your own particle textures to get the exact look and feel you want, code scripts that control certain aspects of the systems, and several other aspects of particle creation. However, that is outside the scope of the book.
Now that we have some rain in our scene, we can see that the sky and the lighting in the scene don’t really reflect a rainy day, so let’s fix that in the next chapter!
