I was wondering if anyone had a method for making normal maps for particles? I am mostly thinking of things like smoke trails and large particle fog, to give it more depth. Example image, haven’t tested the results in Unity (TiBook unfortunately has only a Radeon 7500; and my Mac Pro is about 1600mi away 
):
…would be really great if someone could try this and post a screen with pixel lighting 
yoggy posted a demo that uses this technique here:

as far as generating the maps themselves, i’d imagine either of the usual methods would work fine, model the geometry bake a flat map or use unity’s normal map import setting on a regular image.

I may be just shy of 10 years late but i made a package that does this and comes with the tools to make your own particles
