My last post was about adding snow visualizations into Game #2. In the end I came up with a custom shader that ran faster than an asset I found on the Unity Asset Store. In my (quick) research I didn't find a tutorial showing what I needed, so I thought I'd do a quick series and show my project. The tutorial series covers the full creation of the shader (in Shader Forge) as well as a simple script to control the snow effect scene wide.
If you want to see more details about the creation of the shader or if you'd like to try it out (download link in the video description) then check out my tutorials series. The first video is just an intro and explanation of what's to come. If you want to get to the meat then click here to skip to Video #1.
