Welcome to another one of my mapping tutorials. In this tutorial, I will be teaching you how to add Dust Motes to your map.

Dust Motes is a simple effect that adds dust specs floating around in certain areas of your map. These specs reflect light sources, and are best seen if they are placed under light sources in dark rooms. You can see an example of Dust Motes being used in this screenshot of the map fy_barnyard.




Let's get Started!

1. Open up your map, or quickly create a new one





2. Now, in order for you to notice the Dust motes, you must add in a light source. I've gone in and added a prop_static with a light model, and used the point_spotlight and the light entities for the light source. The settings can be changed to your preference.





3. Now it's time to create the dust motes. Create a brush covered in the tools/toolsnodraw texture, and place it around the light source. This brush will be the area in which the dust motes will appear.





4. Now, select the brush you just created, right click on it, and tie it to an entity, or simply press Ctrl+T. Tie it to the func_dustmotes entity.





5. To make it look better, you should change the following Properties:




• Particle Color: 235 155 71
• Minimum Particle Size: 10
• Maximum Particle Size: 20
• Alpha: 255



The Rest of the settings can be left at default.




6. The final step is to add in an env_cubemap and a spawn point to go test out your newly created Dust Motes.
