@ ice-boy: the answer is yes.  It's a matter of resolution when using the texturing technique.  A 512x512 emblem looks awful when you render closeup in Poser.  Create the same emblem at higher resolution then scale it down when transferred to the texture will yield a sharper image.  Especially when rendering a head & chest render.

Now you could apply decaling to your image in the material room using a separate emblem image of lower resolution and get very decent render.  I have tried and it worked beyond my expectations.  It is a little more involved but worth the effort.

One problem with emblems is applying across material groups.  M3 bodysuit has the arms/chest seams running diagnally towards the neck while V3 & V4 have their seams at the arm and shoulder region.  DecalMaster application @ DAZ claims to solve that issue but I haven't explored that option quite yet.  To use the program, you need a MAT Pose and a fairly decent emblem.  IMHO use hi-res images; my first try at it did not yield good results.
