Creating sand storms/fogs tutorial

[page=Introduction]
Hello there! Here's a tutorial on how to make that 'Sand Storm/Dust Fog' in the air. Let's get started...

[page=Making It]

• First, you should make a brush (block) so your player can walk on. I prefer the 'dev/valuesand40' texture.



• Second, the sand brush (block) you just made will be the ground your player walks on. Select that brush you just made and press CTRL+C
• After doing this, press CTRL+V. You have copied your sand brush. Now, go to the texture browser tab and type/filter 'NODRAW'. It should look like this



• Click the "APPLY CURRENT TEXTURE" tool.
• You should have an exact replica of the sand brush, but with the nodraw texture. Allign the nodraw brush exactly to the sand brush's coordinates in THE TOP COORDINATE
• In the front coordinate, you want to make the nodraw brush stacking on top of the sand brush. So allign it like that.



• After alligning this, select the nodraw brush. You want to make this effect show from the ground to the sky, so bring the nodraw brush's top surface a little bit higher.
• Select the nodraw brush and press CTRL+T. Make this brush a 'func_smokevolume'. Below are some presets i have found out, and you can choose how you want it. (edit the settings for your choice)
