You need to animate your particals first then convert to polygons, in the npartical attributes there change the output mesh settings...........dave The closest thing I could find to what you describe is the output Mesh section in the nparticleshape tab of the attribute editor which is already set to triangle mesh. The nparticles seem to work with transparent blinn but the dielectric and mia glass seem a no go except for 1 occassion that worked for some reason.
