What do I need to do to get sprites to render in a particle emitter?

I watched a short tutorial where the guy shows how to create a snow effect and uses a simple sprite for the actual snow. I am going to show what I’ve learned about LOD in particle effects and wanted to use differently colored sprites at different distances, but when I set the particle render mode to normal instead of the default point, nothing shows.

There’s a few different things that could be happening here…
Did you change any other setting in your emitter? It should work by itself by just changing the material.
Did you test it in the level? It’s possible the sprites are “hidden”/invisible in the editor because of camera angle (lit sprites tend to look pitch black if you look at them from bellow) or bad zoom/scene placement (being zoomed too far can easilly make the camera go through the sprites and make them very hard to see.) I know it sounds kind of dumb but it’s just sooooo easy to accidentlayy misalign your emitter in the viewport and it can be really hard to recenter it again when it happens!

No the results are the same in the level. It must be something dumb I’m overlooking, but I don’t really have time to go through and try everything I can think of. Thanks for your help!
