Snowflakes falling from above

In this final recipe, we create a large plane above the ground, which will slowly drop snow down using a ParticleEmitter object. Although we’re using snowflakes for this example, you can easily swap out the texture for rain, dust, or other things that fall from the sky, or pair it with the cloud that we made in the Making volumetric smoke with particles recipe.

How to do it…

We will begin by creating a large flat plane using a transparent part and then moving it upward along its y axis. Next, we will insert a ParticleEmitter object into the part and modify the Brightness and EmissionDirection properties. We will then insert our snowflake texture and then finish the recipe by changing the particle emitter’s property attributes. To begin, follow these steps:

1. Start by inserting a square part onto the baseplate.
2. Rescale the part to 80, 0.1, 80 studs.
3. Move the part upward along the y axis about 55 studs.
4. Turn the...
