just wanna mention that some poser users may not be able to do advanced IDL renders
with ray-traced trans, reflections, IDL occlusion shadows (not AO) et al., hence there is
a certain logic to baking these things in, even as kozaburo-san useta bake in the hair
hilites back in the old days.  e.g. I still see nostril-glow renders in gallery posts in realism
section.  this may mean:

• they dunno how to render IDL
• it's too slow, hence they skip it
