"As vilters has suggested, your test results are rendered meaningless unless you account for the minimum shading rate and map size for your image based displacement, try a MSR setting of 0.05 (in object properties and render settings) and a map size of 4096. check the results."

Seriously ?

A MSR of 0.05 is complete nonsense.

I never ever used such a low rate in 13 years of using Poser. I usually use 1.25 or sometimes 0.5.

I only used 0.2 for this text to give displacement a fair chance.

And as I said, I don't use maps over 2000x2000 pixel size to save RAM and rendertime.

Using 4096x4096 textures for a final render that is only 2000x2000 pixels at most is a complete waste of time.

Perhaps if you need to do poster sized "museum quality" printouts, but that's not where most Poser renders end up.

Let's be realistic here.

If you demand "professional standards", you shouldn't use Poser.
