Currently Attempting Snow For Particles

This will be a relatively short post, as particle system creation is in the works. I am currently working on a particle system for a bit of snow to go with the snowy farm scene. Right now I am rendering a snowflake texture to a number of quads and randomizing their location, velocity, and other such aspects. Unfortunately, this doesn't translate to the screen at all; a quick HLSL debugging check reveals an actual issue in tracing the shader itself, so I'm wondering what the problem is with that. Tomorrow I'll see if I can try different textures or scaling the texture to see what the problem is. I also anticipate having to use billboarding techniques to rotate each particle toward the camera so the camera can see it.
