I have created some label in photoshop to place on certain items. Lettering is included. However the lettering is readable only when you're zoomed in otherwise it appears as a blur. To partially correct I remove texture flitering.  But still you'll get the letter H withough the crosshatch in the middle, etc. 

Is there a certain font that works better on this? I can't seem to get good results with the lettering showing up satisfactorily.

By the way in preview mode - aside from the artifacting the lettering looks fine from any distance.  It seems to be the firefly render. Suggestions?

Don't know if this is much help but: texture filtering off as you mentioned, Shading Rate less than or equal to 1, pixel samples around 3 X 3. Regarding your font, you can either BOLD it, or choose a font with less contrast between the strokes such as Garamond, Egyptian or Helvetica.

Thank you.  Shading rate 1.0 pixel samples 3 works great. If you change the shading rate to 1.25 then the H doesn't render correctly.  This seems to help and I appreciate it....

If you can switch to the 'Poser 4' renderer, text always looks best there,
with no fiddling needed.   Of course if you're using ray-tracing or
fancy lighting, you can't make that change.....

On Poser 7 change the quality of each texture from "quality" to "none" in the materials room ... makes a huge difference
