Anyone tried creating sprites and fog entities with shade-c?

I mean with these functions;
ENTITY* sc_ent_softFog(ENTITY* ent, VECTOR* color, int inFadeDist, int inSoftness, int inTexMoveSpeed, VECTOR* noiseScale , int pType)

and
ENTITY* sc_ent_softSprite(ENTITY* ent, VECTOR* color, int inFadeDist, int inSoftness, int pType)

I especially wonder how sc_ent_softFog looks like, but I can't seem to get that one working (only see normal map on my entity and not the chosen fog colors).
